Maintenance; General Notes - VOLTCRAFT CHARGE MANAGER 2015 Bedienungsanleitung

Maintenance

Check the technical safety of the charging device at regular intervals, i.e. check it for damage to the
mains power cable, the housing, etc.
If you have reasons to believe that safe operation is not possible any longer, disconnect the appliance
immediately and secure it against inadvertent operation. Pull the power plug out of the socket!
It must be assumed that safe operation is no longer possible, if
- the device exhibits visible damage,
- the device no longer operates and
- the device was stored under unfavourable conditions for a long period of time or
- the device was exposed to extraordinary stress caused by transport.
Always observe the following safety instructions before cleaning or servicing the device:
Live components may be exposed if the covering is opened or components are removed.
Disconnect the device from all voltage sources before performing maintenance work and repairs.
Capacitors inside the device may still be charged, even if the device has been disconnected from all vol-
tage sources.
Repairs must only be carried out by SPECIALISTS familiar with the hazards involved and with the rele-
vant regulations.
For works under voltage, only expressly approved tools may be used.
A damaged mains connection line may be replaced by a specialist only.

General notes

Accumulators consist of two electrodes put into an electrolyte; thus, a battery is a chemical element.
Chemical processes are running inside this element. Since these processes are reversible it is possible
to recharge batteries.
The so-called charge voltage is required for recharging batteries. This voltage must be higher than the
cell voltage. Moreover, the energy (mAh) supplied for the charging process must be higher than the one
that can be drawn afterwards. This ratio of the energy supplied to the energy drawn is called efficiency.
The capacity that can be taken mainly depends on the discharge current; it is decisive for the condition
of the battery. The supplied charge cannot be used as a measure, because a proportion of it will be lost
(for example converted into heat).
