Check the power supply

The tasks described in this section may only
be carried out by a qualified electrician.
Only valid for product variants with phase sequence
relay (AMTRON® Professional+ 7,4 / 22, AMTRON®
Professional+ 7,4 / 22 PnC, AMTRON® Professional
7,4 / 22, AMTRON® Professional 7,4 / 22 PnC).
The product is monitored by a phase sequence re-
lay. It checks the three phases (L1, L2, L3) and the
neutral conductor (N) of the power supply for cor-
rect phase sequence, phase failure or under-
voltage.

u Check the power supply with the aid of the
phase sequence relay.
ð If the green LED (1) lights up, the product is cor-
rectly connected to the power supply.
ð If the green LED (1) flashes, the product is not
correctly connected to the power supply due to
an incorrect phase sequence, phase failure or
undervoltage. The product is not ready for use.
Requirements for three-phase operation
ü The wires of the supply line were correctly con-
nected to terminals L1, L2, L3, N and PE in the
clockwise rotating field.
ü The potentiometer (2) on the phase sequence
relay is set to "3".
If the green LED flashes, the product may
have been connected to the power supply
in the anti-clockwise rotating field. A clock-
wise rotating field is required.
Requirements for single-phase operation
ü The wires of the supply line were correctly con-
nected to terminals L1, N and PE.
ü The potentiometer (2) on the phase sequence
relay is set to "1".
