12 Preventive measures when operating the UPS system
The voltage drop of the supply line has to be kept in mind! The maximum charge current
can cause huge voltage drops if too long supply lines are used. If the voltage drop is too
high a shortfall of the threshold values is possible and a not intended Power Fail could
be caused. With maximum load the voltage at the input of the device must not undercut
11.5 V (UPSI-1208(D)) respectively 22.5 V (UPSI-2406(D)).
Even after the upstream supply has been disconnected, the device continues to run for
some time after the shortfall of the load sensor (setting of a threshold value for current:
currents below this value will be classified as „system off" (no load)).
A short direct at the output of the device can cause damage or destruction. Only from
a certain impedance (L >50 nH, R >50 mΩ) protection can be guaranteed.

Warning!
Disregarding of following issues can result in electric shock, fire, serious
injury or death.
1. The input voltage must be switched off and secured
against unintentional
maintenance or modification work on the entire system.
2. Care must be taken to ensure proper and professional
wiring.
3. Changes or attempts to repair the device are to be omitted.
4. Effects of foreign objects, e.g. metal parts, on the device
must be avoided.
5. The device must not be operated in a humid environment
or in an environment where dew and condensation are to be
expected.
