CAUTION:
Prior to commencing work, ensure that the connection cables are
disconnected from the power supply and that it is not possible to
activate the power supply.
NOTE:
In order to avoid deformation of the supporting rail and to protect
the base of the connection terminal against torsional forces, it is
advisable to hold the cable in position when tightening the
clamping screw (refer to Figure 14/15).
The protective measure of earth connection serves to prevent
excessive touch voltages on freely accessible metal parts. The UPS
is earthed using the earthing bolts (PE) provided on the housing (refer
to Table 2, Chapter 6.4).
Prior to start-up it is necessary to ensure that the UPS is earthed in
accordance with valid regulations (VDE 0100).

Terminal strips X1 and X4 serve as supply inputs. Connection of two
independent circuits, a main circuit and an SBS circuit, or one
common supply circuit is possible.
The battery is connected via X2, and the loads via X3.
