WIRING

VAPORMIST wiring

All wiring must be in accordance with all governing

codes, and with the VAPORMIST or VAPORMIST DI

wiring diagram. The diagrams are located inside the

removable subpanel cover on the right side of the

humidifier cabinet. Power supply wiring must be rated

for 105 °C.

When selecting a location for installing the

VAPORMIST, avoid areas close to sources of

electromagnetic emissions such as power distribution

transformers.

The use of semiconductor fusing sized per the National

Electric Code is recommended with the SSR option.

Grounding requirements

The earth must be made by solid metal to metal

connections. The ground must be a good radio

frequency earth. Ground wire should be same size as

power wiring.

Shielded/screened cable drain wire connection to lug

Note: For maximum EMC effectiveness, all humidity, temperature, and airflow controls should be wired using

multicolored shielded/screened plenum-rated cable with a drain wire for the shield/screen. The drain wire should

be connected to the shield/screen ground terminal with its length kept to less than 2".
