Wire the Relay Cartridge

1. Detach the 4-pin clamp-style removable connector from the relay

cartridge and connect wiring as shown below:

,PSRUWDQW The required wire diameter specification for the relay

cartridge is 12-22 AWG. The wire must be solid,

stranded or fine stranded copper. The maximum length

between the connector and power source/relay must

be less than 10 meters (unless all circuit components,

modules and the power source are located within the

same NEMA enclosure).

,PSRUWDQW As shown in the wiring diagram below, you must

install both of the following:

– an external FLM, slo-blo 0.5A fuse in series with the L1 line

connecting to the 4-pin ARI connector, and

– a surge suppressor (such as Allen-Bradley cat. nos. 700-N5 or -

N24) across the external 700P relay coil

2. Reattach the wired connector to the relay cartridge.
