Warning
The UPS equipment contains components with high voltage and amperage.
Incorrect handling may therefore result in electrical accidents which may have
fatal consequences or cause material damage.
The protective earth conductor must always be connected! If not, the consumer
loads will also not be earthed.
Warning
The connection diagram shown in Fig. 5 only applies if:
o
the loop resistance is complied with up to the last consumer load;
o
the earthing of the consumer loads is ensured;
o
or that the consumer loads are separately protected against overcurrents
and leakage currents, and are also earthed.
Please note that if the UPS equipment is in an emergency OFF circuit and this is
activated, power will still be supplied to the UPS output. The consumer loads will
continue to be supplied for the duration of the support time.
8.3 Connection sequence
Connect the UPS to the mains making sure that the mains and UPS are safely
switched off beforehand.
Connect the consumer load(s) to the UPS. Ensure that all consumer loads are
switched off.
Connect the communication port with your host computer using the cable
supplied.
