Installation

Figure 28. EVP Chiller Remote Panel

Chilled Water Temperature Sensor (Honeywell 6RT2)

With the sensor installed in its proper location within the chilled water piping (Figure 18), connect shielded cable (Belden 8760 or equivalent) from the sensor leads to the leads inside the remote panel. Refer to Figure 28 for the electrical access into the remote panel and the field connection diagram illustrated in Figure 29 for the final cable termination points.

WARNING

Ground Wire!

All field-installed wiring must be completed by qualified personnel. All field-installed wiring must comply with NEC and applicable local codes. Failure to follow this instruction could result in death or serious injuries.

WARNING

Grounding Required!

Follow proper local and state electrical code on requirements for grounding. Failure to follow code could result in death or serious injury.

Note: Connect the shield ground to the ground screw inside the remote panel. Do not connect both ends of the shield to ground.
