Electrical installation
6.1
Electrical connection without
a mains plug
DANGER
Danger to life from electric shock
Mortally dangerous voltage is present at
the connection point of the electrical
network.
❯
Make sure that the connection point is
free of voltage.
❯
Connection to the power supply may
only be performed by a qualified elec-
trician.
❯
Comply with the regulations from the local
power supply companies.
❯
Connect the unit to a power supply source with
a correctly installed protective earth conductor.
(Exception: units with DC permanent-magnet
motors.)
❯
Before commissioning, verify that the power
supply voltage complies with the voltage speci-
fications of the type plate. Ensure that the cur-
rent circuit on the building side has appropriate
fuse protection.
If the unit is permanently connected to the power
supply, a cut-off device (e.g. power circuit
breaker) with a contact gap of at least 3 mm
must be provided in the vicinity of the unit. The
disconnecting device must comply with the stan-
dard 60204-1:2010-05, 5.3.
Comply with the information provided in the
wiring diagrams, label or circuit diagram in the
terminal box when making the electrical connec-
tion.
6.2
IP protection type
The term "IP protection type" (Interna-
tional Protection) is defined by IEC/EN
60529 "Type of protection by housing (IP
Code).
DANGER
Comply with the IP protection type for
protecting the unit against contact,
foreign matter, and moisture
Failure to comply with this information
can result in electric shock, personal
injury, or material damage.
❯
The unit must only be installed or used
in accordance with its type of protec-
tion.
The owner is responsible for ensuring that the
units are only installed or used in accordance
with their protection type.
6.3
Fuse protection of the supply
current circuit
DANGER
Insufficient fuse protection of the
units
Insufficient fuse protection of the units
can result in fire, electric shock, per-
sonal injury or material damage.
❯
Protect the supply current circuits at all
poles in accordance with the nominal
current of the electric motors.
❯
In the case of unmonitored installa-
tions, overcurrent protection in accor-
dance with EN 60204-1:2010-05, 7.2
must be provided.
We recommend the installation of a motor
protection circuit breaker. A minimum of
one line cable fuse with nominal current
+ 10% unless specified otherwise.
