nues using it.
f Eliminate the damage immediately.
f Take the device out of service if necessary.
Precondition:
„ Device is installed correctly.
„ Device is in a proper condition.
„ For versions Professional(+) E 7,4 / 22 only:

circuit breaker, possibly a shunt release) are incorpo-
rated in the indoor installation, and are functional and
switched on.
Î "5.3.2 Providing fuse protection"
„ During the initial setting-up process, the device was
inspected in accordance with IEC 60364-6 and the

6.5 Monitoring the power supply

For versions Professional(+) 7,4 / 22 (PnC) only.
The device is monitored by a phase sequence relay. It
checks the three phase (L1, L2, L3) and the neutral con-
ductor (N) of the power supply for correct phase sequen-
ce, phase failure or undervoltage.
