Installation & Wiring
Mount the appropriate 8 pin octal socket (such as the Macromatic 70169-D or Custom Connector OT08-PC)
in a suitable enclosure. When making connections to the socket, make sure to match the terminal numbers
on the socket to the ones shown on the wiring diagram (the wiring diagram on the relay is the view looking
towards the bottom of the relay vs. the top of the socket). Use one or two #12-22 solid or stranded copper or
copper-clad aluminum conductors with terminals on Macromatic or Custom Connector sockets - a terminal
tightening torque of 12 in-lbs should be used.

The pick-up current setting is user-adjustable within one of three ranges. An
external current transformer can be used to extend the range beyond 10 am-
peres. The drop-out setting is adjustable from 50-95% of the selected pick-up
setting. The relay will energize when the monitored AC current is above the
pick-up setting for a period longer than the adjustable time delay (t) of 0.1-10
seconds. This delay prevents nuisance tripping caused by inrush currents. It
will de-energize when the monitored AC current is below the drop-out setting.
