5.2 Control Terminal Wiring
Analog signal (if connected): all analog signals should be
connected using suitably shielded, twisted pair cables.
Power and Control Signal cables should be routed sepa-
rately where possible, and must not be routed parallel to
each other.
Signal levels of different voltages e.g. 24 Volt DC and 110
Volt AC, should not be routed in the same cable.
Control Cable entries accept a single conductor,
Maximum size: 0.05 – 0.5mm2 / 20 – 26 AWG.
