Follow the procedures contained in the manual
The sequence of manual bypass switching and return must be carried out with
respect to the procedure indicated in the installation and start-up section. The
manufacturer cannot accept responsibility for damages arising from incorrect
operation.
Wiring of the auxiliary contacts
Carry out a proper electrical installation by wiring the auxiliary contacts of the manual
bypass and output isolators to the dedicated terminals on board the UPS. This will
allow the control logic to acquire the status of the switches and guide the operator
during the start-up and manual bypass procedures.
For further information refer to the section "Installation and start-up".
During the manual bypass due to repair or maintenance, the UPS is completely shut down
and the load is directly supplied by the bypass line.
