Liberty Pumps SX-Series - Manual (Page 3)

Mounting the Control Panel
1. Determine mounting location for panel. If dis-
tance exceeds the length of either the fl oat
switch cables or the pump power cables,
splicing will be required. For outdoor or wet
installation, we recommend the use of an SJE-
Rhombus
® liquid-tight junction box with liquid-
tight connectors to make required connections.
You must use conduit sealant to prevent
moisture or gases from entering the panel.
2. Mount control panel (mounting fl anges are
furnished with control panel).
3. Determine conduit entrance locations on con-
trol panel. Check local codes and schematic
for the number of power circuits required.
NOTE: Be sure the proper power supply volt-
age, and phase are the same as the pump
motor being installed. If in doubt, see the pump
identifi cation plate for electrical requirements.
4. Drill proper size holes for type of connectors
being used.
NOTE: If using conduit, be sure that it is of ad-
equate size to pull the pump and switch cables
through. You must use conduit sealant to
prevent moisture or gases from entering
the panel.
5. Attach cable connectors and/or conduit con-
nectors to control panel.
FOR INSTALLATION WITHOUT
A SPLICE, GO TO STEP 11;
FOR INSTALLATION REQUIRING
A SPLICE, FOLLOW STEPS 6-10.
6. Determine location for mounting junction box
according to local code requirements. Do not
mount the junction box inside the sump or
basin.
7. Mount junction box to proper support.
8. Run conduit to junction box. Drill proper size
holes for the type of conduit used. Attach liquid-
tight connectors to junction box.
Installation Instructions
9. Identify and label each wire before pulling
through conduit into control panel and junction
box. Pull pump power cables and control switch
cables through connectors into junction box.
Make wire splice connections at junction box.
10. Firmly tighten all fi ttings on junction box. Insure
all cable connectors are liquid-tight and sealed.
11. If a junction box is not required, identify and
label cables on both fl oat and stripped ends.
12. Connect pump and fl oat wires to proper posi-
tion on terminals. See schematic inside control
panel for terminal layouts.
13. Connect control, alarm and pump power con-
ductors to proper position on terminals. See
schematic inside control panel for terminal
connections.
NOTE: It is the recommendation of the factory
to use separate pump and control/alarm power
sources.
VERIFY CORRECT OPERATION OF
CONTROL PANEL AFTER
INSTALLATION IS COMPLETE.
