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
