Electrical Connections

Follow these precautions when grounding, connecting
cables, connecting to a power source or making other
electrical connections.
To reduce the risk of fire, explosion, or electric shock:
• The control center must be electrically connected to
a true earth ground; the ground in the electrical sys-
tem may not be sufficient.
• All wires used for grounding must be 18 AWG mini-
mum.
• A qualified electrician must complete all grounding
and wiring connections.
• For 24 Vdc wiring refer to F
• For 100-240 Vac wiring refer to F
• Refer to your local code for the requirements for a
"true earth ground" in your area.
NOTICE
If power and grounding connections are not done
properly, the equipment will be damaged and the
warranty voided.
