5.1 Wiring Instructions
(1) Use separate cables for the AC control circuit and Q64TCRT(BW)'s external
input signals to avoid the influence of AC side surges and inductions.
(2) Do not run the module cables near, or bundle them with, the main circuit
and high-voltage cables and the load cables from other than the
programmable controller.
Always place the temperature sensors more than 100mm (3.94inch) away
from the main circuit cables and AC control circuit. Fully keep the sensors
away from high-voltage cables and circuits which include high frequencies,
e.g. inverter's main load circuit.
Not doing so can make the sensors more susceptible to noises, surges and
inductions.
(3) Earth the shielded wire or shielded cable to FG of the programmable
controller.
However, depending on the external noise conditions, external earthing
may be recommended.
