2.5 Electrical Connection
Warning
Potentially fatal voltages are present in the
compressor unit. Before beginning any work
on the compressor unit, switch it off and iso-
late it from the power supply network (lock-
out and tag power).
To avoid electrical shock, always connect
the equipment to a low impedance ground.
The electrical connection/disconnection
shall be made only by a qualified and li-
censed electrician in accordance with VDE
standard 0105, in compliance with the
guidelines set forth in VDE 0100, and
observing local codes.
Set the compressor unit to match the mains
voltage
The compressor unit can be adjusted to operate on any
of a number of line voltages; the factory setting is indicat-
ed in Section 1.3. Observe the specifications shown on
the tag attached to the power cord.
Caution
Where the local power supply differs from
this value, it is absolutely necessary to
reconnect the terminals at the power
module.
To do so, loosen the screws which hold the power mo-
dule on the base plate and pull out the power module.
Take out the 2 screws at the upper edge of the power
module and fold the frontplate forward and down.
Remove 4 screws and take off the left side-panel of the
power module.
A terminal plan is affixed to the side-panel. Compare the
terminal assignment at the transformers with the termi-
nal plan and change as necessary.
Reinstall the left side-panel, fold up the frontplate and
secure it with the screws.
Reconnect the protective earth conductor if it was
removed.
Connect the compressor unit to the mains.
Connect the cold head
Attach the electrical cord from the cold head at the
socket (4/2).
An adapter must be used with cold heads which were
manufactured prior to 1990.
