• refer to the safety instructions.
• ensure that the data on the rating plate of the UPs match those required for
installation.
• any incorrect connection or handling may cause damage to the UPs and/or
the loads connected to it. read these instructions carefully and follow the steps
indicated in the correct order.
• This UPs must be installed by qualified staff and is usable by personal with no
specific training. all staff using this equipment should become familiar with the
contents of this of this “Manual”.
• should a power increase be required in the future through parallel switching,
consider that larger cable diameters may be required. likewise, the additional
installation of an external manual bypass switch for each device is
recommended.
4.1. imPortaNt saFEty iNstrUctioNs
as this is a device with class I protection against electric shocks, it is essential to
install a protective earth conductor (connect earth (( )). Connect the conductor to
the terminal
(X5)
, before connecting the power supply to the UPs input.
all connections in the device, including those for control (interface, remote
control, ...), will be performed with the switches at rest and without any mains
feed present (UPs power line cut off “Off”).
It must never be forgotten that the UPs is a generator of electrical power, users
must take all necessary precautions against direct or indirect contact.
Warning labels should be placed on all primary power switches installed in places
away from the device to alert the electrical maintenance personnel of the presence
of a UPs in the circuit. The label should contain the following or an equivalent text:
Before working on this circuit:
• Isolate Uninterruptible Power system (UPs).
• Then check for hazardous voltage between all terminals including the
protective earth.
