3.3 Wiring
WARNING
Do not disconnect modules or wires unless power has been switched off or the area is known to be
non-hazardous. The devices may only be connected to the supply voltage shown on the type
plate.
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your switches.
2. Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
6. You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be
bundled together
7. You should separate input wiring from output wiring.
8. It is advised to label the wiring to all devices in the system.
3.3.1
Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).
Run the ground connection from the ground screws to the grounding surface prior to connecting
devices.
