parts. The system manufacturer must carry out a check for resonances during commis-
sioning.
4.3 Connection cable & junction box
Information
In demanding environments (wet rooms, outdoor installation), connection cables must
have water draining pipe elbows. If using a junction box, install this lower than the motor
to ensure that water cannot penetrate through to the controller housing from the
connection cables.
4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to
operate the motor/fan for at least 2 hours every month at 80-100 % of maximum speed to
remove any moisture that has penetrated inside.

6 Commissioning
6.1 Prerequisites for commissioning
Attention!
•During commissioning, unexpected and hazardous conditions can arise in the entire
installation due to defective adjustments, resonances, defective components or
incorrect electrical connections.
•Do not start up the motor until all safety instructions (EN 50110, IEC 364) have been
read and understood, safety distances are complied with (EN ISO 13857 / EN 60335)
and hazards have been ruled out.
•Persons and objects must not be located in the danger area.
Information
•Before start-up, acclimatise the motor to the permissible temperature range for
operation (see technical data).
•During erection / start-up operation, the ambient temperature, air humidity, environ-
mental contamination, and corrosion through the surrounding atmosphere must be
taken into consideration.
6.2 Version
Observe the following points before start-up:
•Check for correct electrical connection of the drive motor.
•Check for proper functioning of the ball bearing by turning the rotor by hand. Start-up
is not allowed if the rotor is stuck or there are audible scraping noises.
•Rotor/impeller can rotate freely.
•Installation residues and foreign bodies (e.g. drilling chips, screws) have been re-
moved from the connection area and the motor compartment.
•That safety devices -if necessary- are mounted (see EN ISO 13857).
"Do not connect the motor to the voltage supply until all the conditions are satisfied.
Observe the following points during start-up:
"Check the direction of rotation and if it is not correct switch off the motor and check
the installation.
"Check the motor for smooth and low-vibration running, observing the applicable
standards, e.g. B. ISO 10816.
"Check the entire installation unit for resonance at each speed step.

8 Service work
8.1 Maintenance/servicing
Attention!
Be aware of the following Points:
•Only specifically qualified persons are permitted to perform any work on
explosion protected devices (e.g. TRBS 1203, Section 3.1).
•Wear safety clothing / shoes and cut-resistant safety gloves when handling!
•Please observe the safety regulations and the worker´s protection rules by all
maintenance and service work (EN 50 110, IEC 364).
•Please read the Safety instructions chapter before working on the motor!
•Before working on the motor, this must be disconnected from the power supply
and secured against switching back on!
•No maintenance work at running fan!
•Allow maintenance work to be carried out by trained specialists only.
•For all defects (e.g. cable and wire lead-ins, windings and cables), please contact our
repair department.
•Keep the fan airways free. There is the danger of foreign bodies being sucked in and
objects flying out!
•Check for low-vibration running and abnormal running noises.
•The impeller is subject to natural wear depending on the area of application and the
conveying medium. Regularly check that no deposits have formed on the impeller
which can lead to an imbalance and thus damage (see Chapter: Cleaning).
•Deposits on the motor can lead to reduced cooling and the motor switching off
prematurely. For this reason, remove deposits in good time (see Chapter: Cleaning).
•Maintenance interval in accordance with the degree of contamination of the motor!
•The system constructor must enable easy access for cleaning and inspection work.
•Any faults detected in the electric system/modules/operating equipment must be
corrected immediately. If these faults are not corrected, the device/system is
potentially very dangerous. The device/system must therefore not be operated when it
is faulty.
•check safe isolation from supply with a two-pole voltage detector.
•Wait until the motor has stopped before approaching.
•Do not touch contaminated parts directly (no skin contact).
•Re-attach and start up any safety and protective devices immediately after completing
work. Observe the notes for start-up before recommissioning the device.
8.2 Cleaning
Danger due to electric current
•Voltage supply for motor must be interrupted and secured against restoration!
•Do not use any aggressive cleaning agents when cleaning.
•Make sure that no water gets into the inside of the motor and electronics.
