Installation

Humidifier wiring

All wiring must be in accordance with all governing codes and with

the unit wiring diagram. Power supply wiring must be rated for

105 °C. See Figure 19-1 for the humidifier wiring diagram locations

When selecting a location for installing the humidifier:

• Avoid areas close to sources of electromagnetic emissions such

as power distribution transformers.

• Do not loop power wiring.

• Do not use aluminum wire.

Conduit knockouts

Conduit and control wiring knockouts are provided on the

XT humidifier cabinet. See Figure 8-1.

CAUTION

Adding conduit connections not recommended

Adding alternate conduit connections is not recommended. If you

must make additional holes in the humidiﬁer cabinet, protect all

internal components from debris, and vacuum out the cabinet when

ﬁnished. Failure to follow these precautions can damage sensitive

electronic components and void the DRI-STEEM warranty.

Notes:

• Control wiring and power wiring must be run in dedicated

or separate earthed metal conduit, cable trays, or trunking.

• Separate the line voltage wiring from low voltage control

circuit wiring when routing electrical wiring inside the

humidiﬁer cabinet.

• Do not use chassis or safety grounds as current-carrying

commons. Never use a safety ground as a conductor or

neutral to return circuit current.
