8.3 Electrical connection
Caution:
• The cooling unit must be connected to the mains
by means of a disconnecting device with a contact gap of
at least 3mm when switch off.
•No temperature sensor must be series-connected to the
cooling unit feed.
•The fuse as indicated on the name plate must be
series-connected as line protection.
• Power connection and repairs, if applicable, may only be
carried out by authorized trained electricians.
Power supply connection:
Both mains voltage and frequency must correspond to the
nominal values indicated on the name plate of the cooling
unit.
Attention:
The cooling unit may be damaged if the
voltage is too high. It‟s nominal voltage is 230V or 400V.
Door contact:
In order to avoid any disruptive influences, it is
recommended that a sheathed cable with twisted pair
leads be used.
Caution: No external voltage may be applied.
If no door contact switch is used, the connecting contacts
are to be bridged.
Fault indication:
For connection of the fault signal line there are 1
connection contact and/or connection lines available (see
circuit diagram on the technical supplementary sheet)
The installation of the fault signal line is not subject to any
special requirement.
Caution:
The contact may be loaded with
max.
230V, 1A
