3 INSTALLATION
CAUTION: before performing the following sequence of operations, ensure that the UPS is completely
shut down and is not connected to the mains.
N.B. the installation of a 16A circuit breaker (curve C) upstream from the BYPASS is required. This
protection is necessary if required by the UPS user manual.
WARNING: observing the neutral (N) and phase (P) indications relating to plugs and outlets, the BYPASS
inserted in a system does not change the existing neutral system. The neutral system will still be modified if
an isolation transformer is present.
For versions with output cable: the blue wire identifies the neutral cable, while the yellow-green wire
identifies the earthing cable.
