Electrical installation
Connecting electrically charged lines is extremely dangerous and parts of the
system can be damaged. The local regulations must be observed at all times
for electrical installations.
Further, the following basic principles must be observed:
It is essential that the protective conductor is connected.
It is essential that the unit and purge air heater are connected to the mains
via a fault-current automatic breaker (earth leakage circuit breaker).
Because the unit has no mains switch, a suitable disconnector (switch,
plug) should be installed near the mains connection.
The mains supply must have a back-up fuse with a tripping current of 16A.
If faults cannot be remedied, the unit must be put out of operation and
protected against inadvertent operation.
All electrical connections are made with spring clamps inside the control unit.
The control unit can be opened by undoing the four screws under the side
covers.
