Mains connection
Compare the setting of the rated supply voltage of the UPS to
the rated voltage applicable for your country. The ex-works
presetting of the UPS output voltage is 230 V AC. Changes to
208 V AC, 220 V AC, 230 V AC or 240 V AC can be made via
the operator panel.
To ensure proper functioning of the UPS and its additional
equipment, it is necessary to provide the mains supply cable with an
appropriate back-up fuse. With all models of the Protect B.
PRO
series, connection is carried out using the included mains
connection cable to a conventional safety socket. Ensure suffi-
cient power rating of the fuse in your subdistribution. The more
powerful models as from Protect B.2300
PRO, in particular, require
their own 16
A fuse protection. Do not yet plug the safety plug of
the mains connection cable into the intended safety socket.

Electrical load connection
Before connecting the electrical loads to the UPS, please check
whether the specified rated output on the rating plate is greater
than or equal to the total electrical load output.
Connect the intended electrical loads to the outlets of your UPS.
Use the included electrical load connection cables for this pur-
pose. Pay attention to the sub-division of the output sockets here
(see also Section 5.2 on Page 26). Important electrical loads
which must be powered continuously should be connected to
continuously energised outputs. The manageable output circuit is
used for electrical load segmentation. You will leave your
electrical loads switched off at first. Should additional electrical
load connection cables be required, please contact your specialist
dealer.
If a shared distribution cabinet is used (circuits with
both mains and UPS power), label each circuit with
the respective feed (mains or UPS).
