Operating Guide | VACON® 1000
For the control signals, use multi-core wire with a shielding layer, wherein the shielding layer is equipotentially grounded at both
l
ends and is not too long.
The wires used to transmit different signals must be routed in an alternative and mutually vertical way (staggered), for example AC
l
signal and DC signal.
6.9 Control Wiring
6.9.1 Control Cable Selection
Control power cables
Use low-voltage cables with PVC or XLPE insulations of copper, with shield, and in single or multi-core constructions.
Cable specification for input voltage 208–600 V:
Solid type cable, 2.5–6.0 mm
l
Flexible type cable, 4.0 mm
l
Cable specification for input voltage 120 V:
Solid type cable, two parallel connected cables, 2.5–6.0 mm
l
Flexible type cable, two parallel connected cables, 4.0 mm
l
Control signal cables
Use control cables with XLPE or PVC insulation, with screening, and in multi-core constructions.
Solid type cable, 1.0–4.0 mm
l
Flexible type cable, 2.5 mm
l
Encoder cables (optional)
Recommended cable types:
8-core shielded twisted pair, 4x2x0.5 mm
l
If cable length is 0–50 m, use one 8-core shielded twisted pair
l
If cable length is 51–200 m, use two 8-core shielded twisted pairs, where 1 of the wires is connected with 4 cores in parallel and used
l
as a power supply wire.
Ground the shielding of the encoder cables at both ends.
6.9.2 Control Power Wiring
Connect L and N of the control power to terminals 1 and 7 in terminal block Y12. See
