Replacing storage batteries VKPN 40
■ Make sure that the data collector is switched off before replacing the storage battery!
■ Save data before replacing the storage battery in order to avoid loss of data.
■ Make sure that the data collector VKPN 40 is not connected via connecting cable VKPA 40 when replacing the storage
battery.
■ Incorrect charge levels are indicated after the replacement of the storage battery unit.
It takes two charging/discharging processes before the correct state of charge can be indicated.
■ Do not remove the storage battery pack as some of the acid electrolyte might escape during the process.
■ Do not throw storage batteries in water or fire (risk of explosion)!
■ Old storage batteries should not be disposed of with normal household waste – hand them in at your recycling centre.
Maintaining VKP 40
When used for its intended purpose the diagnostic system is maintenance-free. However, we recommend that the system should be
sent to GESTRA AG Bremen every 5 years for a general inspection.
Spare Parts
The storage battery must be replaced when its charging capacity is no longer sufficient for the test tasks. For this purpose remove the
6 screws from the bottom of the equipment. Detach the upper part of the equipment from the lower part. Attention: The upper part is
connected to the lower part via a ribbon cable. This cable connection must not be detached. The storage battery unit is embedded with
protective elements on a green board. This unit is fixed to the bottom of the equipment by means of 4 screws. In order to exchange
the battery this whole unit has to be replaced by a genuine GESTRA AG spare part. Undo the 4 screws and remove the battery
unit. Put the new battery unit onto the two centric items of the connector. Insert two M.5 mm screws and fasten them with  Nm,
then insert the other two M3 screws and fasten them with .5 Nm. Then mount the two halves of the equipment together, making
sure that the gasket is properly inserted and the ribbon cable is not jammed between the two equipment parts. Mount the 6
casing screws and tighten them with a torque of 0.8 Nm. The battery can now be charged as described in section “Charging storage
batteries”. Note that full capacity of a new storage battery is only obtained after about 5 complete charge and discharge cycles.
Environmental regulations have to be taken into account when disposing of storage batteries.
