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.
