STEP 2: INSTALLING AC POWER CONNECTIONS TO THE SURGEGATE AC

BASE UNIT

Note: ITW Linx surge protectors require that you have a properly grounded
3-wire outlet to protect the connected equipment. The protector is
equipped with a green "Ground OK" diagnostic light to indicate
proper power grounding. The "Ground OK" light will not come on
and the red "Line Fault" indicator light will come on if your AC outlet
is improperly wired (reverse polarity or no ground present).

1. Turn OFF the power to all equipment that will be plugged into the surge protector.
2. Make sure the ON/OFF switch is in the OFF position, plug the unit into the
wall outlet, and then turn it on. See Figure 4.
3. Once proper AC wiring and grounding has been established via a green "Ground
OK" light, plug the equipment to be protected into the AC outlets on the unit.
4. One at a time, turn each piece of connected equipment ON and check for
power and correct operation.
5. Turn OFF the unit, as well as all connected equipment before installing modules.

Note: If the KSU/PBX has a "Ground" terminal, connect it to the top
(right) of the top SurgeGate module. Use a minimum #14 green
insulated copper wire, with a ring terminal at each end. Route the wire
as directly as possible. Do not make any other connections to the
ground terminal of the KSU/PBX.

STEP 3: CONNECTING SURGEGATE MODULES

Note: For proper installation, the line(s) between the KSU/PBX and the
module(s) must be a minimum of 6 feet in length to avoid surge
damage. Never install telephones during a lightning storm.

1. Connect the telephone CO lines to the “LINE” jacks on the SurgeGate
module. Use the modular cords provided to connect the “EQUIPMENT”
modular jacks to the KSU/PBX CO line connections.

B.) SurgeGate CO/4-110 and CO/8-110 Modules (Secondary Protector)
The SurgeGate CO/4-110 protects 4 CO (Central Office) lines using 110
punchdown connectors on the input, and 110 connectors or RJ-11/45 on
the output. The CO/8-110 modules are designed to protect KSU/PBX
systems with up to 8 CO lines using 110 punchdown connectors on both
the input and output.

1. Cut the cable from the primary protector to the correct length and punch
down the cable to the “LINE IN” punchdown block on the module.
2. Punch down another cable to the “EQUIP OUT” punchdown block on the
CO/4-110 or CO/8-110 module and connect to the KSU/PBX, or to use
modular outputs on the CO/4-110 module skip to step 4.
3. Secure any cables connected to punchdown blocks with the reusable
cable ties installed on the CO/110.
4. Connect an RJ-11 or RJ-14 modular cable to each RJ-11/45 output jack
on the side of the CO/4-110 module, using the schematic diagram on
the face of the module as a connection guide.
C.) SurgeGate CO/25 Modules (Secondary Protector)
The SurgeGate CO/25 modules are designed to protect
KSU/PBX systems that are connected to more than
8 CO (Central Office) lines. These units are very cost
effective for protecting more than 8 CO lines and
up to 25 CO lines.

1. Install the Velcro clamps provided on the protector RJ-21x connectors.
Mount the protector on the SurgeGate assembly.
2. Connect the RJ-21x connector from the 66 block to the "LINE" jack
on the SurgeGate module. Some KSU/PBX systems
use RJ-14 connections for the incoming CO lines.
In this case, an octopus cable (RJ-21x to (8)
RJ-14s) may be required from the “EQUIPMENT”
jack to the KSU/PBX connection.

FOR T-1 EQUIPMENT
The SurgeGate T1/ISDN module is wired to accept standard, straight-
through cords on both the Line and Equipment sides. No crossover cords
or other special cables are needed when using T1 (or other RJ48C
compatible) lines.

FOR LEASED-LINE EQUIPMENT

To protect equipment that is wired for RJ48S cords (pins 1, 2 and 7, 8), a
custom cable will need to be made. See “Connecting the SurgeGate
T1/ISDN Module” sheet, 9026-180-00.

(Pins 7 & 8 need to be moved to positions 4 & 5 in order to pass through
the SurgeGate module.)

STATION SET LINES

A.) SurgeGate DS/25 Module (Secondary Protector)
(You must use primary protection before the station set protectors). The
SurgeGate DS/25 module is designed to protect KSU/PBX systems that are
connected to up to 25 digital station sets. If analog (tip and ring) sets are
used, you must use a CO/25 module.
1. Install the Velcro clamps provided on the protector
RJ-21x connectors. Mount the protector on the
SurgeGate assembly.
2. Connect the RJ-21x female cable to the remote
building into the “LINE” side of the DS/25 module.
3. Connect one end of a RJ-21x male cable
(not provided) into the “EQUIP” side of the SurgeGate module. Connect
the other end to the KSU/PBX.
4. Secure the RJ-21x connections to the DS/25 with the hook and loop
hold-down straps.

B.) SurgeGate DS/2 Module (Secondary Protector)
The SurgeGate DS/2 is designed to protect Digital Station (DS) set lines for
KSU/PBX systems.
One SurgeGate DS/2 module protects two 4-wire digital station sets or two
KSU/PBX digital station lines.
1. Connect the digital station line to the "LINE" jack on the SurgeGate
module. Use the modular cords (provided) to connect the "EQUIPMENT"
jack to the KSU/PBX digital line connection.

MDS/2, 70 volt protection, RJ-11/45
compatible, pins 3, 4, 5, 6.

OTHER CONNECTIONS

A.) SurgeGate DS/CO Module (Secondary Protector)
The DS/CO module protects two 4-wire digital/analog lines or two 2-wire
tip/ring analog lines using RJ-11/45 connectors.
1. Simply plug the RJ45 jack from the line input cable into the “Line” side
of the protector. Using a patchcord, plug one end into the “Equipment”
side of the protector and the other side of the patchcord into the
equipment to be protected.

B.) SurgeGate CAT 5e Modules (Models: CAT5-LAN, CAT5-POE,

CAT5-75, CAT5-235, CAT6-LAN, CAT6-POE, CAT6-75, CAT6-235)
These models protect one 8-wire Cat5e or CAT6 cable using 110 connectors.
1. Remove protector cover.
2. Strip off 1.5" of jacket from line input 24 AWG OSP cable and protected
equipment cable.

3. Insert OSP cable (“LINE” side) into clip on the printed circuit board. If
shielded cable is used, contact shield with the clip.
4. Punch down line input pairs on the 110 connectors (“LINE” side)
carefully maintaining proper wire twist. (Note: The color code is printed
on the PC board next to the connector.)
5. Punch down the protected equipment pairs on the opposite 110
connectors (“EQUIPMENT” side) carefully maintaining proper wire twist.
(Note: The color code is printed on the PC board next to the connector.)
6. Position and tightly secure a cable tie on each cable to provide strain
relief next to cable exit holes in the protector housing.
7. Replace cover.
8. Mount protector to a solid surface, like plywood. Drill a 3/32 hole for the
#6 x 3/4 screw and eyelets provided. See figure 3 on page 2. Attach
screw and eyelet to wall and slide protector over screw and tighten. Add
second screw to bottom of protector.
9. When used as a Primary Protector, connect the grounding strip to a
good earth ground with a minimum 10 AWG wire. Use ring lug and
machine screw provided. Route wire as direct and as short as possible.
For Isolated Loop applications, connect to a single point ground with a
minimum 14 AWG wire as shown in figure 4 below.
10. Additional protectors may also be bonded together as shown in figure 5
below (dotted outline. Connect to a single point ground with a 6 AWG wire).

CENTRAL OFFICE (CO) LINES

A.) SurgeGate CO/4 and CO/4X4 Modules (Secondary Protector)
The SurgeGate CO/4 and CO/4X4 modules are designed to protect CO
(central office) lines. If you have more than 8 CO lines, we recommend
that you use a SurgeGate CO/25 module that uses an RJ21x connector, or
a CO/4-110 or CO/8-110.

D.) SurgeGate LL/T1 Module (Secondary Protector)
The SurgeGate T1/ISDN is a secondary protector designed to protect T-1
or ISDN lines. Each SurgeGate T1/ISDN module will protect two T-1 lines
or two ISDN lines.

3. Mount protector to a solid surface, like plywood. Drill a 3/32 hole for
the #6 x 3/4 screw and eyelets provided. See figure 3 on page 3. Attach
screw and eyelet to wall and slide protector over screw and tighten.
Add second screw to bottom of protector.
If you are not using a SurgeGate base unit, connect the protector to a single point

ground with a minimum 14 AWG wire as shown in figure 5 on page 3. Additional

protectors may also be bonded together as shown in figure 5 on above.(dotted outline.

Connect to a single point ground with a 6 AWG wire).
