Electrical Connections

To reduce the risk of fire, explosion, or electric shock, when grounding, connecting cables, connecting to a power source or making other electrical connections:

•The control center must be electrically connected to a true earth ground; the ground in the electrical system may not be sufficient. Refer to your local code for the requirements for a “true earth ground” in your area.

•All wires used for grounding must be 18 AWG min- imum.

•A qualified electrician must complete all grounding and wiring connections.

•For 24 Vdc wiring refer to FIG. 13.

•For 100-240 Vac wiring refer to FIG. 14.

•Incoming power wiring must be guarded from the enclosure. Use a protective grommet where the power wiring enters the enclosure to prevent wear.

NOTICE

If power and grounding connections are not done properly, the equipment will be damaged and the warranty voided.
