UPSI-2406DPx
F18 Preventive measures and rules 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 vol-
tage 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 22.5 V.
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 of the UPS. In the event of a fault,
electrolytes can escape in liquid and gaseous form.
