(figure 3 is typical) can be shared among multiple monitored out-
put circuits. If a supply is to be shared, between Monitored Out-
put Circuits wired to a common PCB, use the short power supply
jumpers shown on page 1. The jumpers can be used on T11–T15.
Refer to Table 4 for jumper functions.

A supply can be wired to be shared among multiple PCBs in the
same cabinet (figure 4 is typical). To share among multiple PCBs:
use the long power supply jumpers (shown on page 1) to connect ei-
ther T10 or T16, of one PCB, to either T10 or T16 of the other PCB.
An EOL relay must be used for every external power supply (fig-
ures 2–3 are typical). The EOL relay coil should always be con-
nected at the external power supply input of the module which
is connected farthest away from the power supply. The EOL relay
contacts should always be connected in series with the Monitored
Output Circuit wiring of the same module. The EOL relay coil
should be connected across the PS+ (red wire) and PS- (black
wire) if it is connected at T0 – T5. The EOL relay coil should
be connected across adjacent pins (red – even pin#, black – odd
pin#), of the same connector, if T10 – T16 are used.
All cabling must comply with local standards or codes of practice.
All external power supplies must be voltage regulated with bat-
tery back-up.
*NOTE 1: EOL Relay Coil Connections must be
made using EOL Relay Connector Assembles on
T10-T16 in event that all monitored Output Circuits
+
on the PCB have dedicated supplies.
