Operating instructions

R3G400-AQ23-68

Translation of the original operating instructions

3.7 Electromagnetic compatibility

If several devices are switched in parallel on the mains side so
that the line current of the arrangement is in the range of 16 - 75
A, then this arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power S

sc

at the connection point of the

customer system to the public power system is greater than or
equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S

sc

value that is greater than or equal

to 120 times the rated output of the arrangement.

4. CONNECTION AND START-UP

4.1 Connecting the mechanical system

CAUTION
Cutting and crushing hazard when removing the fan
from the packaging
→ Carefully hold the impeller to remove the device from its

packaging. Make sure to avoid any shock.

→ Wear safety shoes and cut-resistant safety gloves.

CAUTION
Heavy load when taking out the device
Bodily harm, e.g. back injuries, are possible.
→ Two people should remove the device out of its packaging

together.

; Check the device for transport damage. Damaged devices must no

longer be installed.

; Install the undamaged device according to your application.

4.2 Connecting the electrical system

DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.

DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation

requirements for voltage, current, insulation material, load etc.

→ Route cables such that they cannot be touched by any

rotating parts.

DANGER
Electrical load (>50 µC) between mains wire and
protective earth connection after switching of the supply
when switching multiple devices in parallel.
Electric shock, risk of injury
→ Make sure that sufficient protection against accidental contact

is provided.
Before working on the electrical connection, the
connections to the mains supply and PE must be shorted.

CAUTION
Electrical voltage
The fan is a built-in component and features no electrically
isolating switch.
→ Only connect the fan to circuits that can be switched off with

an all-pole separating switch.

→ When working on the fan, you must switch off the

installation/machine in which the fan is installed and secure it
from being switched on again.

NOTE
Interferences and failures are possible
Maintain a distance to the power supply line when routing the
control lines of the device.
→ Ensure a sufficiently large clearance.

Recommendation: clearance > 10 cm (separate cable
routing)
