Measure the resistance of the anti-condensation heater at the ter-
minals in the operating mechanism and compare it with the referen-
ce value in the routine test certificate. Enter the values in the
checklist.
Serious personal injury or property damage can result during
commissioning if the equipment is live or energized.
Therefore:
- Make sure the supply and control cables are not live befo-
re connecting them.
The mechanism's charging process will begin immediately after
the supply and control voltages are connected.
Therefore:
- Keep parts of the body and other objects away from the
moving parts of the operating mechanism and the entire
connecting linkage.
The anti-condensation heater will heat up after the supply and
control voltages are connected. Touching the anti-condensation
heater can result in burns.
Therefore:
- Do not touch the anti-condensation heater.
• Insert the supply and control cables through the cable entry plate
on the underside of the operating mechanism. This plate must be
fitted with cable glands by the station (and can be removed for
repairs or maintenance). Connect the cables in accordance with
the schematic diagram.
