13 START-UP
Note
When setting power plants with nominal voltages of up to 1000 V, the requirements of
VDE 0100 as well as its relevant standards and regulations must be observed.
A main switch must be provided externally.
The electrical supply circuit must be equipped with a slow fuse of 10 A. The electrical
indications are in the technical data.
For option RS back purge:
The control circuit of the solenoid valve must be equipped with a slow fuse of 0.1 A.
A residual current protective device (RCD) with a rated value of the fault current of
not more than 100 mA must be used.
The radiator must be covered by a metal protective cover.
(Put on the weather protection cover of the probe.)
Before starting, check that the mains voltage is identical with the indication on the type plate.
Warning
The heated equipment must be mounted tightly. Make sure that there is a minimum
distance of 100 mm [approx. 3.9”] to other components in order to prevent an accumu-
lation of heat.
Switch on the mains supply.
Attention! In case of ambient temperatures higher than 40 °C [104 °F], the temperature
of the protective or isolation cover is higher than 60 °C [140 °F].
The total heating time is approx. 2 h. The signalling is carried out by the temperature status alarm.
