or removed and also that no screws etc. fall into the charger. Remove all metallic objects that
have fallen into the charger.
-
Clean the charger with dry compressed air. Keep a distance of at least 20 cm to
the components while doing so in order to avoid any damage to them. Fix the fan
while cleaning
-
Check the fan for ease of running and replace it if necessary
-
Remove dust or dirt on the charger with a dry cloth
-
Check the housing for visible signs of damage.
-
Check the insulation of the charger cable and the mains cable for external
damage. Repair or replace defective parts
-
Check the charger and mains plug for external damage. Repair or replace
defective parts
Put the charger back into operation:
-
Check whether the connecting plug or screws have come loose. If necessary,
tighten them
-
Close the housing door and fix it to the housing again with the screws
-
Check the charger regularly. The DGUV V3 testing has to be conducted annually,
bi-annually when deployed at construction sites or every 3 months
-
Put the battery charger back into operation and check that it is working properly

On an annual basis
1. After full charging in accordance with 7.2 and an optimum rest period of 24 hours (at
least 12 hours), the following must be measured and recorded:
a)
Total voltage
b)
Individual cell voltages
c)
Cell surface temperature (measured at pole or container)
If significant changes to previous measurements or differences between the individual
cells are detected, a request for further checking or maintenance must be made to
customer service. A significant change occurs when the voltage deviates from the mean
value of the cell voltages or from the last measured voltage of the same cell greater than
0.015V.
2. Remove dust from the chargers (Please observe the charger operating manual
instructions).
Carefully check:
a)
The condition of the plug connections for signs of mechanical and thermal damage;
the contacts in particular must ensure good current conduction.
b)
The condition of the connecting cable.
3. The insulation resistance of the vehicle and the battery must be checked in accordance
with EN 1175-1 on an as-required basis, but at least once annually by a qualified
electrician. The check of the battery insulation resistance must be carried out in
