Geo Direct PWM Amplifier

Connector PinOuts and Wiring 29

The black wires are for the thermostat and the white wires are

for the shunt resistor.

The shunt resistor incorporates a normally closed (N.C)

thermal overload protection thermostat that opens up when the

core temperature of the resistor exceeds 225°C (450° F). This

thermostat is accessible through the two black leads. It is

important that these two leads be wired in a safety circuit to

halt operation should the resistor temperature exceed the

specified threshold.

The external shunt resistor Ohm rating range is found so that

the minimum value limits the current to the permissible

amperage, and that the maximum value limits the bus (during

deceleration) to the permissible voltage.

Note

For GPL models, the shunt circuitry turn-on threshold is 392 VDC

(~278 VAC). The turn-off threshold is 372 VDC (~263VAC).

Note

For GPH models, the shunt circuitry turn-on threshold is 784 VDC

(~555 VAC). The turn-off threshold is 744 VDC (~526VAC).
