Figure 2-2. Power Plug
2.4.1 24 V DC Power Connections
Figure 2-3. 24 V DC Power Connections
Refer to Figure 2-3 to make the following connec-
tions:
1. Connect the positive (+) 24 V input line, via an
SPST switch, to L1 of the power plug. As
shown in Figure 2-3, the positive input should
come from a distribution strip; do not daisy-
chain the input power from one controller to
another. Leave the SPST switch in the OFF
position.
2. Connect the negative (-) input line to L2 of the
power plug. As shown in Figure 2-3, the nega-
tive input should come from a distribution strip;
do not daisy-chain the negative input from one
controller to another. The distribution strip
should be connected to a noise free earth ref-
erence as shown in Figure 2-3.
3. Connect the chassis safety ground lug of the
power plug to the ground wire.
NOTE: DO NOT APPLY POWER TO THE
CONTROLLER.
(Applying power is performed in Section 2.9.)
2.4.2 AC Power Connections
Figure 2-4. AC Power Connections
Refer to Figure 2-4 to make the following connec-
tions:
1. For 110/120/220 V ac, connect the phase and
neutral inputs to the power plug. For 240 V ac,
connect the two phase inputs to the power
plug.
2. Connect the chassis safety ground lug of the
power plug to the ground wire (green, green-
yellow).
NOTE: DO NOT APPLY POWER TO THE
CONTROLLER.
(Applying power is performed in Section 2.9.)
2.5 Signal Connections
Figure 2-5 illustrates the signal plug location on the
controller backplane. The signal plug is removable
and can be pulled straight out from its backplane
connector. The plug is scalloped on one side to
ensure proper insertion after the signal wires are
connected. Figure 2-6 illustrates the signal wire
connections.
NOTE: Each signal wire lead should be stripped
to expose 1/4 inch (6.4 mm) conductor.
