NOTE: Not all generators require four control wires to operate. Some may combine the CRANK and ON function in which case the CRANK wire is not required. Additionally, select generators are controlled by a 240VAC signal from the transfer switch. If you need assistance with your particular
4.4 Connecting the Low Voltage Cable to the Generator
There is a terminal block in the wiring compartment of the generator to connect the power cables and the low voltage wire to control the generator. Some generators use 2, others 4 control wires. Refer to the generator installation manual for proper connection.
1.Connect the PIN 1 wire from the transfer switch to the battery
2.Connect the PIN 2 wire from the transfer switch to the battery “+” (positive) terminal.
3.Connect the PIN 3 wire from the transfer switch to the ON/OFF terminal on the generator. This wire starts and runs the generator. If your generator has a 2 or
4.Connect the PIN 4 wire from the transfer switch to the Crank or Start terminal (only used on generators having a separate Start terminal.) The PIN 4 wire is not used if there is no specific Crank/Start terminal on the generator.
4.5Installing and Wiring PowerPause™ Load Management Modules (optional)
Optional PowerPause™ Load Management Modules (Figure 4.5.1) are required when the load connected to the generator exceeds the generator capacity and dynamic load management is needed. Each PowerPause™ Load Management Module can control up to 2 loads; up to 3 Load Management Modules can be installed into each Control Module, 6 (240V) managed loads in total (or 12 x 120V loads). Load management priority
is determined at time of installation.
1.Remove Control Module from transfer switch. Refer to Figure 4.1.1.3.
a.Remove branch circuit breaker (if installed) opposite controller module.
b.Slide Control Module ½” towards circuit breaker bus stabs (towards center of enclosure).
c.Pull up outside end of Control Module ¾”so that controller module is tilted up about 30° degrees.
d.Pull Control Module off of circuit breaker bus stab.
2.Unplug all cables from the Control Module. Cable marking is not required, as connectors are uniquely keyed; each connector can only be inserted into its proper location.
3.Remove five (5) screws holding black plastic shield in place. Set aside screws. See Figure 4.5.3.
4.Rotate shield ¼ turn, align three (3) top holes and one (1) side hole to metal enclosure,
5.Refer to completed TABLE 3.4 for POWERPAUSE™ LOAD MANAGEMENT CIRCUIT PRIORITY. Note the
