General Wiring Recommendations

Risk of Electric Shock: Turn off power before any kind of servicing to avoid electric shock. However, it is not necessary to
remove power when hot-swapping SELV ECY IO module front assemblies (see Hot-swappable ECY IO Modules).
£ 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.
£ Always use unshielded cabling with a minimum Category 5e (CAT5e) cable for ethernet communications.
£
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.
£ When connecting one wire to a controller's terminal block clamping cage (pole), the wire must be between 18 and 14 gauge (0.82 and 2.1mm
cross-sectional area). When connecting two wires to a controller's terminal block clamping cage, both wires must be the same thickness, must be
between 18 and 16 gauge (0.82 and 1.3mm
sert then into the controller's terminal block clamping cage. For any other wiring combination (mixed wire thickness, mixed solid and stranded con-
ductors, 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.

£
Do not connect the universal inputs, analog/digital outputs or common terminals to earth or chassis ground (unless stated otherwise).
£
Keep input and output wiring in conduits, trays or close to the building frame if possible.
