6.5 - Power cable access routing
The power cables for devices are routed into the electrical box
from the side of the electrical cabinet.
A removable aluminium plate on the side of the electrical cabinet
provides access for the power cables.
It is important to check that the power cable bend radius is
compatible with the connection space available inside the electrical
cabinet.
Refer to the certified dimensional drawing for the unit.
6.6 - Field-installed control wiring
Connecting the interface circuits on-site creates
certain safety risks; any modification to the electrical
box must ensure the equipment remains compliant
with local regulations. In particular, precautions must
be taken to prevent accidental electrical contact
between the circuits supplied by different sources:
- The choice of routing and/or insulation
characteristics of the conductors ensures double
electrical insulation.
- The conductors should be fixed together inside
the electrical box to prevent contact between the
end of the conductor and a live part in case of
accidental disconnection.

diagram supplied with the unit for the field control wiring of
the following devices:
- Remote On/Off switch

6.7 - Electric power reserve for the user
Control circuit power reserve:
After all possible options have been connected, the CT transformer
ensures the availability of 1 A of power for the control cabling
on-site on 24 V, 50 Hz.
With the electrical plug option, this CT transformer provides
a 230V, 50Hz circuit to power laptop battery chargers only,
maximum current of 0.8 A at 230 V
Only connect class I and II equipment to this power
socket.
