5.3. Overcurrent protection / insulation monitoring device
ATTENTION:
The power supply circuit is to be protected through an all pole
overcurrent protection device acc. to table Technical Tata on page
23.
If the overcurrent device has been triggered, the heater is to be switched
off. It is essential that the cause is identified and the error rectified by a
qualified electrician in a specialised workshop. Only then the heating
appliance can be reconnected to the mains.
The use of overcurrent protection devices with another as specified load
ability is not permitted and will result in loss of the operating approval!
The heater must be protected on the vehicle side with all poles by
an insulation monitoring device (tripping resistance 0.5 M
Ω
)
against fault currents.
If the Thermo DC is monitored as a subcomponent of the BUS
system, the value can be adapted according to the applicable
statutory requirements.
The connecting schematic of the insulation monitoring device is shown
in figure 5 (for example if monitoring the stand alone device).
The specified for the fasteners torque value must be met.
High voltage! Danger to life!
