Caution
Follow the rules below when wiring inputs and outputs:
• Never lay wires across the surface of the printed circuit board. You should
bring input wires in from the left and output wires in from the bottom.
• High voltage AC Power wiring should be routed to the conduit
opening nearest the AC power terminals.
• Do not bundle or route AC Power wiring with low voltage input or
output wiring.
• Bundle excess wires toward the back of the cabinet to avoid any
contact with circuit boards.
• Wires should never be within 1 in. (25 mm) of any component on the
printed circuit board.
• Keep cabinet free of foreign materials (extra power supplies, relays,
and so on).
• Be careful when stripping wire not to drop small pieces of wire
inside the cabinet.
If you violate any of these rules, the controller could malfunction.
