Charging the battery for emergency
operation
Julian has a built-in uninterruptible power supply UPS
which maintains the power supply for 30 minutes in the
event of a mains failure, provided that the battery is
charged.
The switch-over to the battery-powered UPS is automatic
and is indicated on the screen by the message:
POWER FAIL!
The battery recharges automatically when the workstation
is plugged into the mains.
The battery must be charged for 10 hours before using
the Workstation for the first time.
Plug the mains plug of the Julian workstation into the
mains socket. The mains voltage must correspond to
the voltage specified on the nameplate.
