Control of electrical parts
■
During maintenance and repair work on eclectic
parts, safety checks must be carried out: see
below.
■
If there is a high importance fault for safety,
you should not connect the installation before
removing the fault. If it is not possible to
immediately remove the fault, as far as possible,
you must find the appropriate temporary solution
to work on the installation. Notify the installation
user.
Perform the following security checks:
■
Discharge of capacitors: Make sure that the
discharge process does not arise.
■
When pouring or draining the refrigerant, and also
when rinsing the refrigeration circuit, do not place
electrical parts or wires that are under voltage in
close vivinity to the device.
■
Check the grounding connection.

Repair of sealed enclosures
■
Disconnect the device from voltage during work
on sealed components before removing the
sealed cover.
■
To warn of a potentially dangerous situation, a
permanent refrigerant detector should be placed
in critical places.
■
Particular care should be taken not to modify
the housing in a way that weakens its protective
effect when working with electrical parts. This
includes damage to wires, the creation of too
many connectors on one connection terminal,
the creation of connectors that do not meet the
manufacturer's requirements, damage to gaskets
and incorrect installation of cable pass-throughs.
■
Ensure that the device is installed correctly.
