voltage. The simultaneous operation of electronic devices in the same backup
power supply system should be avoided.
Load unbalance
When dimensioning three-phase backup power networks, the total output power
and the power output per phase of the inverter must be taken into account.
IMPORTANT!
The inverter may only be operated within the limits of its technical capabilities.
Operation outside of its technical capabilities can cause the inverter to shut
down.

Protective
earthing (PE)
Connection of a point in the device, system or installation to earth to protect
against electric shock in the event of a fault. When installing a safety class 1 in-
verter (see Technical data), the ground conductor connection is required.
When connecting the ground conductor, ensure that it is secured against acci-
dental disconnection. All the points listed in the chapter Connecting the invert-
er to the public grid (AC side) on page 52 must be observed. It must be ensured
that when using the strain relief devices, the ground conductor is the last to be
disconnected in the event of a possible failure. When connecting the ground con-
ductor, the minimum cross-section requirements specified by the respective na-
tional standards and guidelines must be observed.
