Attention!
The batteries built-in in this system are designed for the necessary bridging time
at nominal load of the UPS. A no-load running operation of the UPS with a long
time in battery operation could led to battery damages. This effect is determined
by the technique of the battery, as the cut-off voltage will not be reached at a
long discharging time.

General information
Only qualified personal is allowed to open the UPS.
The connection of the UPS has to be done according to VDE considering the local rules.
Don't cover the ventilation slots at backside of the UPS. Keep a distance to the surrounding walls of at least 100
mm.
The UPS is built up according to protection class
IP21
and has to be installed in dry and clean rooms with a
surrounding temperature of 20 °C. A lower operation temperature would decrease the autonomy time.
Don't connect devices with connection-cables exceeding the length of
10 meters
. This measure serves for the
observance of the EMV-norm.
It's not allowed to carry out structural changes on the UPS. Improper operation causes the extinction of warranty.
Relevant information!
To prevent self discharging of the batteries you have to connect the UPS to
mains and put it into operation within four weeks after receipt!
Attention:
To prevent overload or a frequent switch-over to bypass mains caused by non-sinusoidal current peeks
of the connected loads you shouldn't connect laser printer, faxes or similar devices to the UPS.
If it's necessary to connect such devices to the UPS, you have to choose an UPS with a higher nominal
power than the maximum of the current spikes.
The power semiconductors of the UPS could be immediately destroyed by the connection of loads with a
half-sinusoidal rectifier.
The battery isn’t galvanic isolated from the mains, so it’s possible that there is mains-potential at the
battery-terminals!
