4.2.1.
ELECTRICAL NETWORK
The system is linked to the mains power supply via a cable with
2
or
3
wires + ground connected to the controller.
Various power supply voltages are possible: 200V, 208V, 230V, 400V, 440V, 480V (50/60Hz) ± 10 %. The choice
of the power supply voltage and the type of network (single phase or three-phase) depend on the option selected
and the type of arm used.
When making the connections, the ground wire must be connected first.
Power rating to be installed:
Minimum wire cross section: 14 AWG / 2 mm
2
Maximum wire cross section: 8 AWG / 6 mm
2
(flex wire)
Maximum wire cross section: 7 AWG / 10 mm
2
(solid wire)
Maximum tightening torque applicable on terminal block screw: 1.8 Nm
Note:
The controller is fitted with a filter to limit the induced disturbances (disturbances caused by the
controller). The filter can cause major leakage current peaks that have to be taken into account
when selecting the elements protecting the power supply circuit (using a time delay ground fault
circuit breaker). Leakage current can reach up to
250 mA
for
3 ms
. Nominal leakage current for
3-phase and single phase configurations is below
3 mA
.
CAUTION:
Make sure that the voltage supplied corresponds to the voltage shown on the manufacturer's
plate of the
CS8C
controller.
TX40 1,5 kVA
TX60 1,7 kVA
TX90 2 kVA
RX160 3 kVA
RS40B, 60, 80 1,7 kVA
DANGER:
Use a cable whose cross-section is suitable for the power rating shown on the
manufacturer's plate and protect the line accordingly.
