Power cable arrangement
Multiple double-shielded twisted-pair cable
Multiple shielded twisted-pair cable
A double-shielded cable is the best alternative for low-voltage digital signals, but a single-shielded or
unshielded twisted multipair cable (Figure b) is also usable. However, for frequency input, always use
a shielded cable.
Note
: Run analog and digital signals in separate cables.
The relay cable needs the cable type with braided metallic screen.
The keypad needs to connect with cables. It is recommended to use the screen cable on complex
electrical magnetic condition.
Do not make any voltage tolerance or insulation resistance tests (for example hi-pot or megger) on
any part of the inverter. Every inverter has been tested for insulation between the main circuit and the
chassis at the factory. Also, there are voltage-limiting circuits inside the inverter which cut down the
testing voltage automatically.
Check the insulation of the input power cable according to local regulations before connecting to the
inverter.

Note
:
It is appropriate to use the recommended cable size under 40
˚C
and rated current. The wiring
distance should be no more than 100m..
