Installation

3.8.3

Connect the motor thermistors (if fitted)

You must connect the thermistor terminals in the motor to a suitable control circuit, to shut down the HV pump

system if the motor temperature is too high. An example control circuit is shown in

Figure 4

You must use a suitable two-wire cable and a suitable cable-gland to connect the thermistors cable (from your control

circuit) to the thermistor terminals in the motor. The cable-gland (and adaptor, if fitted) must provide a protective

seal to IP44 (or higher), as defined by IEC 529. Refer to the Motor Manual supplied with your motor for the sizes of

the thermistor cable-gland holes in the motor.

Make the thermistor connections in the motor as described in the Motor Manual supplied.

3.8.4

Connect the motor thermostats (if fitted)

You must connect the thermostat terminals in the motor to a suitable control circuit, to shut down the HV pump

system if the motor temperature is too high. An example control circuit is shown in

Figure 4

You must use a suitable two-wire cable and a suitable cable-gland to connect the thermostats cable (from your

control circuit) to the thermostat terminals in the motor. The cable-gland (and adaptor, if fitted) must provide a

protective seal to IP44 (or higher), as defined by IEC 529. Refer to the Motor Manual supplied with your motor for the

sizes of the thermostat cable-gland holes in the motor.

Make the thermostat connections in the motor as described in the Motor Manual supplied.

3.9

Earth (ground) connection

Note that:



We recommend that you connect the booster pump to a suitable factory/plant earth (ground).
