Do not connect the UPS with machines which could overload it (e.g. laser
printer).
The sum of earth fault currents of all with the UPS connected machines should
not be higher than 3.5mA.
Keep the access lines short and always connect them correctly. Dagers as to
stumble, to squeeze, etc. have to be avoided.
3.5 Operation
During the operation of the UPS, the feeder never has to be uncoupled,
otherwise the protective grounding of the UPS and of the connected machines
would be cut.
The UPS has got an energy storage (batteries). Therefore the output can be
conducting, also if the input of the UPS is not connected.
To switch-off the UPS completely, please follow the instructions of chapter 9.7.
Keep the UPS free of liquids and foreign particles.
