Maintenance and Care
It is not necessary to open the housing of the device to commission and operate the
system. Opening the housing causes the immediate termination of all warranty claims!
The connections and connection leads of the system must be regularly tested to ensure
that they are free of defects and intact, in accordance with the applicable national and
company-specific arrangements.
If the device is not used for a lengthy period, it should be stored in a dust-free and dry
environment. Continuous moisture (humidity) especially when combined with dust can
reduce critical insulating clearances that are essential for safe high-voltage operation.
Store the unit always at a full state-of-charge. Apply topping charge every six months.
The internal battery can be recharged in two ways:
•
Through the mains connection lead, which connects the power supply
socket to an appropriate mains socket
•
Through the motor vehicle charging cable, which connects the charging
socket
with the 12 V DC on-board voltage of a motor vehicle
As soon as one of these connections is made, the display is activated and the progress
of the charging process is shown. It takes about 4 to 6 hours to charge the battery
completely.
As soon as the device is switched on, the charging process is interrupted, i.e.
charging is not possible whilst it is in operation!
If the device cannot be switched on when the power supply is connected, the two fuses
which are located next to the power socket
should be checked. The fuse holder
must be pulled out.
If broken, the fuses should be replaced with appropriate type M6.3/250 micro-fuses
(5 x 20 mm).
