5. Electrical power supply cold room
A 4-pole socket outlet is located on the intake-side of the Refrigeration evaporator unit for the electrical power supply to the
loads attached to the coldroom, with a total power capacity of
max. 250 VA (lighting, door frame heating).
The door contact switch can also be connected to this sokket
outlet.
5.1 Connecting the door contact switch
The evaporator ventilator should be switched off when the
cold storage cell is opened. For this reason, we recommend
the installation of an potential-free door contact switch (switching capacity 230VAC, min. 0.5 A).
Connection takes place via the 4-pole socket outlet mounted
on the intake-side of the evaporator unit.
In its delivered condition, the unit is functionally ready for
service without an external door contact switch.
The door contact switch is not included within the scope of
delivery of the unit.
If a door contact switch is connected to the refrigeration unit,
the regulation parameter must be changed (see also Point 9.3,
Menu Settings).
This is achieved through the following menu items:
