Charging the battery for emergency

operation

Primus has a built-in uninterruptible power supply
UPS which maintains the power supply for at least
30 minutes (up to 90 minutes, depending on the
ventilation parameters) in the event of a mains
power failure, provided that the battery is charged.
Switching to battery power (UPS) takes place auto-
matically, and is indicated on the screen by the
message: POWER FAIL.
The battery recharges automatically when the
workstation is plugged into the mains, but only up to
a maximum ambient temperature of 35 °C (95 °F).
WARNING
Risk of device failure
If the batteries have not been sufficiently
charged and a power failure occurs, it may not
be possible to continue operation for long
enough.
Charge batteries for at least 8 hours before
first use or after storage.
The battery must be charged for 10 hours before
using the workstation for the first time:
Plug the mains power plug of the Primus work-
station into the mains socket.
The mains voltage must correspond to that speci-
fied on the rating plate on the back of the machine.

The green LED (A) lights up.
Leave Primus connected to the electrical power
supply for 10 hours. It does not need to be switched
on.
CAUTION
Risk of device failure
In the event of a power failure, any devices con-
nected to auxiliary power outlets will not be pow-
ered by the UPS.
Pay special attention to all power indicators of
connected devices.
CAUTION
Risk of electric shock and of device malfunction
There is a risk of injury to the user or damage to
the device if the device is connected to a power
outlet with the wrong mains voltage or without a
protective conductor.
The power cable must only be connected to a
power socket with a protective conductor, see
''Technical Data''.
