Installation & Connection
AC10 Inverter
7.7.3 Field Wire Connections
Control cables, input power cables and motor cables should be installed separately and enough
clearance should be left among the cables, especially when the cables are laid in parallel and
the cable length is over 50 metres. If the signal cables must be laid with the power cables, they
should be installed parallel to each other.
Generally, the control cables should be shielded cables and the shielding metal net must be
connected to the metal enclosure of the drive by cable clamps.
7.7.4 Earthing
Independent earthing poles (best) Shared earthing pole (good)
Shared earthing cable (not good)
Note:
1. In order to reduce the earthing resistance, flat cable should be used because the high
frequency impedance of flat cable is smaller than that of round cable with the same CSA.
2. If the earthing poles of different equipment in one system are connected together, then the
leakage current will be a noise source that may disturb the whole system. Therefore, the drive’s
earthing pole should be separated with the earthing pole of other equipment such as audio
equipment, sensors and PC, etc.
3. Earthing cables should be as far away from the I/O cables of the equipment that is sensitive
to noise, and also should be as short as possible.
