Power Supply Connection - Xylem Lowara e-LNEEE Manual De Instalación Y Funcionamiento

NOTICE:
• Install the control cables separate from the
power supply cables and the fault signal
relay cable
• If the control cables are installed in parallel
with the power supply cable or the fault
signal relay, the distance between the
cables must exceed 200 mm
• Do not intersect the power supply cables;
should this be necessary, a 90°intersection
angle is permitted.

Power supply connection

WARNING: Electrical hazard
Contact with electric components may cause
death, even after the unit has been switched
off. Before any interventions on the unit, the
network voltage and any other input voltages
must be disconnected for the minimum time
indicated in Para. 5.1.
WARNING:
Only connect the electronic drive to Safety
Extra Low Voltage circuits (SELV = very low
safety voltage). Circuits intended for use with
external communication and control
equipment are designed to ensure insulation
from the dangerous adjoining circuits inside
the unit. Communication and control circuits
inside the unit are floating in relation to the
mass and are classed as SELV. They must
only be connected to other SELV circuits, in
order to maintain all the circuits within the
SELV limits and avoid mass loops. The
physical and electric separation of the
communication and control circuits from non-
SELV electric circuits must be maintained
both inside and outside the inverters.
Power supply wiring procedure
1. Open the terminal box cover (2) by removing
the screws (1).
2. Insert the power cable in the M20 cable gland
(5)
3. Connect the cable according to the wiring
diagram.
4. Connect the earth conductor (mass), making
sure that it is longer than the phase
conductors.
5. Connect the phase leads.
