Keep in mind that if more than one battery pack is supplied, the connection will always be in parallel with
the equipment. For instance, the black cable from the UPS negative terminal to the negative of the first
battery pack and from this one to the negative of the second battery pack, and so on. Please, proceed in
the same way for red cable for positive, blue for half tap (N) and green-yellow for earthing.
Electrical discharge danger
. If after starting up the UPS, the battery cabinet needs to be
disconnected, the equipment has to be completely shutdown (see section 5.2). Turn off the battery fuse
holder switch (Q8) located in the battery cabinet and/or fuse holder switch or switch (Q3) located in the
UPS. Wait at least 5 min. until the filter capacitors have been discharged.
4.3.5
Main protective earthing terminal ( ) & protective earth bonding terminal ( ).
As this is a device with class I protection against electric shocks, it is essential to install a protective
earth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting the
power supply to the UPS input.
Make sure that all the loads connected to the UPS are only connected to the protective earth bonding
terminal ( ). The fact that the earthing of the load(s) and/or the battery case(s) or cabinet(s) is not
restricted to this single point will create return loops to earth which will affect the quality of the power
supplied.
All of the terminals identified as protective earth bonding ( ), are joined together and to the main
protective earthing terminal ( ) and to the frame of the device.
