application of the series SupraBox COMFORT (SBC) of Rosenberg Ventilatoren
GmbH.
12 Maintenance, Servicing
Maintenance and servicing should only be done by trained and instruct-
ed staff and when taking all relevant rules and regulations into consider-
ation!
Usually our control box is maintenance free! Under extreme conditions minor mainte-
nance work may be necessary!
When working at the control box of the SupraBox COMFORT (SBC) the guidelines for
the electrical safety must be maintained and divide from the voltage
If repairs are necessary they have to exclusively be made by a Rosenberg Ventilator-
en GmbH authorized technician.
All changes and repairs at electric connections may only be made by an authorized
electrician. Checking of the insulation resistance according to DIN EN 60204 -1 or
VDE 0113 -1 4.1 is recommended.
For the maintenance and service the protective conductor system and the automatic
shutdown in case of error must always be checked.
13 Accessories and Field devices
The
sensors for fresh air or return air temperature
are constructed as duct sen-
sors. The wiring at the switch cabinet should be made using a shielded cable (J-Y (St)
Y 4x 0, 6). The shield has to be connected to the switch cabinet and to the ground
terminal in the sensor housing. Polarity of the connections at the switch cabinet and
the duct sensor does not affect the measurement precision. As the Supraboc Comfort
is already equipped with sensors in the union, special duct sensors for the use of heat
exchangers (e.g. heating coils, cooling coils) are recommended. If a heating/cooling
coil of Rosenberg Ventilatoren GmbH is ordered, a corresponding duct sensor is in-
cluded in the delivery scope of the coil.
Rosenberg Item Code: H42-09926
The
room temperature sensor
is suitable for wall fastening. The wiring is made with
use of a shielded cable like for the duct sensor. Also in this case the polarity does not
affect the measurement precision. The use of a room temperature sensor is pre-
condition for the function of the backup mode and ventilation at night.
