conductors - four poles for three phases.
1-4. Connection Warnings
• This UPS should be connected with TN grounding/earthing system.
• The power supply for this unit must be three-phase rated in accordance with the equipment nameplate.
It also must be suitably grounded.
• Use of this equipment in medical instrument of any life-sustaining equipment where failure of this
equipment can reasonably be expected to cause the failure of the life-sustaining equipment or to
significantly affect its safety or effectiveness is not recommended. Do not use this equipment in the

system, for example a contactor, which will prevent the appearance of voltage or dangerous
energy in the input mains during a mains fault (see figure 24 and conforms to the wiring diagram of
«Backfeed Protection» depending on the phase input).
There can be no derivation in the line that goes from the «Backfeed Protection» to the UPS, as
the standard safety would be compromised.
