CONNECTION AND START-UP
4.1
Mechanical system connection
CAUTION
Cutting and crushing hazard when removing the
device from the packaging.
→ Carefully remove the device from its packaging by
the fan housing. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Heavy load when unpacking the device
Risk of physical injury such as back injuries.
→ Two people should work together to remove the
device from its packaging.
Check the device for transport damage. Damaged devices
must no longer be installed.
Install the undamaged device according to 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
Electrical connection
DANGER
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
→ Ensure sufficient protection against accidental
contact.
Before working on the electrical connection,
disconnect the mains supply and PE.
CAUTION
Voltage
The fan is a built-in component and has 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
Device malfunctions possible
Route the control lines of the device separately from
the supply line.
→ Maintain the greatest possible clearance.
Recommendation: clearance > 10 cm (separate
cable routing)
NOTE
Water ingress into wires or cables
Water ingress at the end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a
dry environment.
→ The IP protection is guaranteed only if the
provided cable glands 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 name plate agree with the
connection data.
Before connecting the device, ensure that the power supply
matches the device voltage.
Only use cables designed for current indicated on the name
plate. For determining the cross-section, follow the basic
principles in accordance with 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.
Earth wire contact resistance in accordance with EN 61800-5-1
Compliance with the impedance specifications in accordance
with EN 60335 for the protective earth circuit must be verified in
the end application.
Depending on the installation situation, it may be necessary to
install an additional protective earthing conductor via the
additional protective earth connection point available on the
device.
4.2.2
Supply connection and fuses protection
Assignment of supply cable cross-sections and their fuses (line
protection only, no equipment protection).
