5. WIRING
5.1 Wiring Instructions
(1) Use separate cables for the AC control circuit and Q64TD/Q64TDV-GH's
external input signals to avoid the influence of AC side surges and
inductions.
(2) Always place the thermocouple/micro voltage signal cable at least 100mm
away from the main circuit cables and AC control circuit lines.
Fully keep it away from high-voltage cables and circuits which include
harmonics, such as an inverter's load circuit. Not doing so will make the
module more susceptible to noises, surges and inductions.
(3) Insulation-sleeved crimping terminals cannot be used with the terminal
block.
It is recommended to fit mark tubes or insulation tubes to the wire
connection parts of the crimping terminals.

*1:As cables, always use shielded compensation conductors.
Also, wire the shielded cables as short as possible.
*2:Always connect to the earth terminal of the control box.
