clipped to the cover below.
Always use the wire gauges as specified in the installation instructions. Conductor
terminals should always be protected by suitable metal sleeves.
The electrical installation must be designed to enable disconnection (isolating) of the
power supply connection point from the mains.

Connecting of the UPS unit may be carried out only by
suitably qualified service technicians, with professional licences required
by law.

pack with a high combined potential). This means there may be a hazard
of dangerous voltage appearing at the unit’s output even though the
device is not connected to external power.

system are used as one of the UPS unit’s protection levels. The parameters of the
building's electric wiring system protection should be selected to meet the
requirements of the load connected to the wiring system and the type the load. In
extreme cases, different characteristics of the building’s and the UPS unit’s electrical
protection systems may result in the former system being activated earlier.
CAUTION!
The user is under obligation to place the following warnings
on all the cut-out switches or isolating switches located remotely from the
UPS unit:
“BEFORE STARTING WORK ON THIS CIRCUIT MAKE SURE TO:
- DISCONNECT THE UPS SYSTEM
- CHECK IF THERE IS VOLTAGE BETWEEN ANY OF THE TERMINALS (BY
CONNECTING THE PE TERMINAL)
