•Opening of the base lid is prohibited. Loosening the safety screws will void the
guarantee!
–Protection class of the device when complete open is IP00! It is possible to
touch hazardous voltages directly.
–Through use of capacitors, danger of death exists even after switching off the
device!
•The rotor is not protected against indirect contact neither by supplementary or
reinforced insulation nor by connection to safety-earth in accordance with EN
60204-1, therefore the system constructor must provide protection by enclosure in
accordance with EN 61140 before the motor is connected to a power source. This
protection can be achieved for example by a guard grille (
Product overview:
Application operational area and Installation: General).
•When the motor runs independently due to air flowing through or if it continues to
run down after being turned off, dangerous voltages of over 50 V can arise on the
motor internal connections through operation of the generator.
•The safe isolation from the supply must be checked using a two-pole voltage
detector.
•Even after disconnecting the mains voltage, life-threatening charges can appear
between the protective ground “PE” and the mains connection.
•The protective earth is conducting high discharge currents (dependent on the
switching frequency, current-source voltage and motor capacity). Earthing in
compliance with EN specifications shall therefore be observed even for testing
and trial conditions (EN 50 178, Art. 5.2.11). Without earthing, dangerous voltages

Information
In demanding environments (wet areas, open air installation) all connections must
incorporate water drainage curves. To ensure that water cannot penetrate through to the
controller housing from the connections install a terminal box lower than the fan.
In vertical mounting (installation position “H” motor shaft horizontal), install the fan for
protection ahainst penetrating moisture with the terminal compartment vertically
downwards (up to max. 30° lateral inclination).
Optimum heat dissipation of the power loss resulting in the device is achieved in this
position (
Diagnostic/ Faults / Temperature Management).

Information
•Pay attention to a sufficient screw-in length in the motor flange.
•An excess screw length of max. 3 mm is permissible.
•Every screwing case is different. The tightening torque adapted to it must be
determined by the appropriate screw tests.
•In the case of a vertical motor axis, the respective lower condensation drain hole
must be open.
•Secure fan connection cable with cable fasteners or cable clips.
A minimum head gap “A” of 2.5 mm in all installation
positions but especially in installation position “H”
(horizontal motor shaft) is necessary. Distortion due
to uneven surface may lead to fan failure due to
brushing against the fan wheel.
Attention!
Avoid structural damage or stress with installation. Make sure the surface is flat and
even.

Fastening depending on housing design on flange or fastening brackets.
Information
An additional bracket is required for fastening to the flange. This is available as an
accessory.
Ensure that the clearance (gap) “a” see fig. be-
tween the fan impeller and the stationary housing
section is constant. Distortion due to uneven sur-
face may lead to fan failure.
Attention!
•Avoid structural damage or stress with installation. Flange and mounting bracket
must be fixed flat on a level surface.
•Provide screwed connections with suitable screw locking.
4.4.3 Erecting the equipment: Design ER... / GR...
•To avoid the transference of disruptive vibrations, we recommend de-coupling the
entire plug fan to avoid sounds transmitted through solids. (Spring and/or attenu-
ation units are not a constituent part of the standard scope of delivery). Look at
our catalogue for positioning the decoupling elements or request a dimensions
sheet stating the type designation and Part.-No.
•Erect in the open air only if this is expressly mentioned and confirmed in the
ordering information. There is a risk of damage to the bearings if the fan remains
stopped in a moist environment. Avoid corrosion by suitable protective measures.
Roofing is required.
•In the case of a vertical motor axis, the respective lower condensation drain hole
(if available) must be open.
•The GR design in position “ H ”should be installed in the preferred direction. The
cable guides should point downwards (angled sideways by approx. 30°). This is
indicated by the “OBEN/TOP” warning sign on the device.
Attention!
•All contact points must be fixed securely. If the fixing is inadequate there is a risk of
the fan overturning.
•Making your own alterations/conversions on the fan module is unacceptable -
safety risk.

4.5 Mounting of motors
Motors design MK
Fastening to fixed motor flange
(assembly of axial fans / fans of design A, D ..) and
(assembly of radial fans of design RH).
•If the motor is used to drive fan impellers or other components, please note the
maximum permissible speeds of the impeller or the component to be driven.
•The max. permissible mass of the impeller ort he component to be driven must be
inquired from and confirmed in writing by ZIEHL-ABEGG.
Design K (with rotor flange) or D (with offset rotor flange) as a drive for fans:
•During assembly of the fan impellers or other components, no inadmissible force
may be applied to the motor bearing.
•Centre the fan impeller accurately and mount without tension on the rotor flange,
the fan wheel must lie flat.
•Use suitable screws for fastening the fan impeller on the rotor flange and fit as
suitable screw lock.
•Every screwing case must be tested for suitability.
•The permissible area pressing of the rotor flange may never be exceeded (de-
pending on the contact surface).
•Too great a screw overhang is not permitted and can lead to scraping or blocking
of the rotor on the fixed motor flange.

4.6 Outdoor fans in a humid atmosphere
Information
If a fan is stationary for long periods in a humid atmosphere, it should be switched ON for
minimum of two hours every month to remove any moisture that may have condensed
within the motor.
4.7 Motorheating
A continuous power supply is required for safe operation down to the minimum permitted
outer temperature (
technical data).
If the motor is not switched on with an existing power supply (no setting signal, switch off
by enable), the motorheating switches back off automatically at a controller inside
temperature of -19 °C and heating up to -15 °C.
Heating takes place via the motor winding whereby a current is induced which cannot
cause rotation.
