4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Cutting and crushing hazard when removing blower
from packaging
→ Carefully remove the blower from its packaging, touching
only the housing. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
;
Check the device for transport damage. Damaged devices 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 Electrical connection
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 charge (>50 µC) between phase conductor 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 hookup, short the supply
and PE connections.
CAUTION
Voltage
The device is a built-in component and has no disconnecting
switch.
→ Only connect the device to circuits that can be switched off
with an all-pole disconnection switch.
→ When working on the device, secure the system/
machine in which the device is installed so as to prevent it
from being switched back on.
NOTE
Device malfunctions possible
Route the device's control lines 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 customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
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.
;
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
AWG 26 / 0.13 mm².
Ground conductor contact resistance according to EN 60335
Compliance with the impedance specifications 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 earth conductor to the extra protective
earth terminal on the device.
4.2.2 Reactive currents
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and immunity to interference),
reactive currents can be measured in the supply line even
when the motor is at a standstill and the line voltage is switched
on.
4.2.3 Locked-rotor protection
Due to the locked-rotor protection, the starting current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connecting the cables
The device has external leads.
;
First connect the "PE" (protective earth).
●
Connect the cables according to your application. When doing so,
observe Chapter 4.4 Connection diagram.
