Thermo AC/DC
1 Introduction
NOTE:
The provisions of these Regulations are binding within the
territory governed by DGUV Regulations and should
similarly be observed in countries without specific regula-
tions.
Country specific rules / standards are to be considered
additionally.
Even before the start of non-electrical work, the
voltage- freeness must be determined by a skilled
electrician.
1.6.2 Emergency stop / de-energizing
The Thermo AC/DC heaters itself do not have an emer-
gency stop system. Their control and power supply is
integrated into the vehicle's electrical system.
It is therefore the responsibility of the user to inform
himself before the commisioning of the heater in the
vehicle how the heater can be successfully de-energized
if necessary (maintenance, service work, abnormal beha-
vior etc.).
1.6.3 Work at the heater
Installation, maintenance and repairs may only be
carried out when the vehicle's engine is not running
and the high voltage supply (AC/DC) / power supply is
switched off.
Before starting the work at the heater, it is to make
voltageless acc. to DIN VDE 0105-100 and this state
must be ensured for the duration of the work.
The following safety precautions must be observed:
–
switch off the power supply to the heater
–
ensure it cannot be switched on again
–
verify system is voltage-free, all poles
–
ground and short circuit (the de-energized circuit)
–
cover or block neighbouring parts under voltage
Electrical cables and operating elements of the heater
must be arranged in the vehicle in such a way that
their functioning is faultless under normal operating
conditions and cannot be hampered.
Work at electrical equipment may only be started if
protective measures against electric shock, short
circuits and arcing faults have been carried out.
Familiarize yourself with the Thermo AC/DC Installa-
tion instructions before you make any modifications
to the existing heater installation.
NOTE:
The Installation and operating instructions contain the
statutory regulations and other safety hints and regula-
tions for the proper installation of the heater.
Further they contain safety instructions and regulations to
be followed for safe operation of the heater.
1.6.4 Other safety information
1.6.4.1 Temperature sensors
ATTENTION:
The cables of the temperature sensors (temperature
limiter, control thermostat) may not be mechanically
stressed (pull on the cable, carry the heater at the
cable etc.).
