CONNECTION AND START-UP
4.1
Mechanical connection
CAUTION
Cutting and crushing hazard when removing the
fan from the packaging.
→ Carefully remove the device from its packaging,
touching it only by the wall ring. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
Check the device for transport damage. Damaged decvices
are not to be installed.
Install the undamaged device in accordance with your
application.
CAUTION
Possible damage to the device
If the device slips during installation, serious damage
can result.
→ Ensure that the device is securely positioned at its
place of installation until all fastening screws have
been tightened
4.2
Connecting the electrical system
DANGER
Voltage on the device
Electric shock
→ Always connect a protective earth first.
→ Check the protective earth.
DANGER
Faulty insulation
Risk of fatal injury from electric shock
→
Use only cables that meet the specified
installation regulations for voltage, current, insulation
material, capacity, etc.
→
Route cables so that they cannot be touched
by any rotating parts.
DANGER
Electrical load (>50 µC) between mains wire and
protective earth connection after switching off
supply with multiple devices connected in parallel.
Electric shock, risk of injury
→ Ensure sufficient protection against accidental
contact.
Before working on the electrical connection, short the
mains supply and PE connections.
CAUTION
Voltage
The fan is a built-in component and has no
disconnecting switch.
→ Only connect the fan to circuits that can be switched
off with an all-pole separating switch.
→ When working on the fan, secure the system/machine
in which the fan is installed so as to prevent it from
being switched back on.
CAUTION
Electric shock
Voltage on metal part
→ Use the device only with the cable guard and
terminal box intended for it.
NOTE
Water ingress into wires or cables
Water enters at the customer end of the cables can
damage the device.
→ Make sure the end of the cable is connected in a
dry environment.
→ The degree of protection is only assured when the
intended cable guard and terminal box are
installed.
Only connect the device to circuits that can be
switched off with an all-pole disconnection switch.
4.2.1
Requirements
Check whether the data on the nameplate match the
connection data and the data of the operating capacitor.
Before connecting the device, make sure the power supply
matches the device voltage.
Only use cables designed for the current level indicated on
the nameplate.
For determining the cross-section, note the sizing criteria
according to EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than that of the phase
conductor.
We recommend the use of 105°C cables. Ensure that the
minimum cable cross-section is at least AWG26/0.13 mm².
Ground conductor contact resistance according to EN 60335
Compliance with the impedance specifications in according to EN
60335 for the protective earth connection circuit must be verified
in the end application.
Depending on the circumstances of installation, it may be
necessary to connect an additional protective earthing conductor
to the extra protective earth terminal on the device.
4.2.2
Voltage control
With open loop speed control using transformers or
electronic voltage regulators (e.g. phase angle control),
excessive current may occur.
In addition, noises can occur with phase angle control
depending on the mounting situation.
