Installation
example for
battery current >
85 A
Where batteries for an electrical load greater than 85 A are being used, the consumer
must be connected in parallel with them.
Deviations in the case of energy cell 50F:
-
The 5 - 10 kOhm pre-resistors indicated thus * are required
-
The battery voltage is 48 V instead of 24 V
WARNING!
An inadequate or missing fuse protection for the batteries or
improper handling of batteries can cause dangerous situations and result in
serious injuries and damage. The power cable for the energy cell is to be
protected by a 100 A fuse at the point where it connects to the battery. The
applicable national and international regulations regarding the safe installati-
on of batteries and the information provided by the battery manufacturer
must be observed.
