LEGRAND KEOR HPE 60 kVA Operating Manual page 1243

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.
