General Wiring Recommendations

Risk of Electric Shock:

Turn off power before any kind of servicing to avoid electric shock.

£ All wiring must comply with electrical wiring diagrams as well as national and local electrical codes.

£ To connect the wiring to a device, use the terminal connectors. Use a small flat screwdriver to tighten the terminal connector screws once the wires

have been inserted (strip length: 0.25’’ (6mm), maximum tightening torque 0,4 Nm (3.45 in-lb)).

£ Comply with all network and power supply guidelines outlined in the Network Guide.

£ Keep wiring separate according to their function and purpose to avoid any ambient noise transmission to other wires. Use strapping to keep these

wires separated. For example, keep power, hazardous voltage, SELV, PELV, network, and input wiring separate from each other.

£ Power cables must be between 18 and 14 gauge (0.82 to 2.1mm

cross-sectional area). When connecting one wire to a controller’s terminal block

clamping cage (pole), the wire must be between 22 and 14 gauge (0.33 and 2.1mm

cross-sectional area). When connecting two wires to a con-

troller’s terminal block clamping cage, both wires must be the same thickness, both wires must be between 22 and 16 gauge (0.33 to 1.3mm

cross-

sectional area), and both wires must be of the same type (solid or stranded). Twist the wires together and insert then into the controller’s terminal

block clamping cage. For any other wiring combination (mixed wire thickness, mixed solid and stranded conductors, more than three wires, wire

thickness is out of range), twist the wires together and use a wire nut and a pig tail to connect to the controller’s terminal block connector as show

below.

£ Keep input and output wiring in conduits, trays or close to the building frame if possible.
