Translation of the original operating instructions
;
Check the device for transport damage. Damaged devices are not to
be installed.
;
Install the undamaged device in accordance with your application.
NOTE
Motor capacitor
→ The product is equipped with a motor capacitor with safety
protection class P0/S0 according to EN 60252-1. Take this
into consideration when fitting it to the end product on the
basis of applicable regulations.
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.
Recommendation for fastening AxiCool fan with screws: (based on VDI
2230)
;
Use screws of strength class 8.8.
;
For sizes 500 and 630, screws M8 with a tightening torque of max.
20 Nm.
;
For size 800, screws M10 with a tightening torque of max. 40 Nm.
The tightening torques specified above are based on the following values
are only valid for them:
●
The contact surfaces must be flat.
●
The fan must not be strained on fastening.
●
As every application is different, the tightening torque recommended
by ebm-papst must be checked in the application concerned.
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 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 disconnection 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.
NOTE
Water ingress into wires or cables
Water ingresses at the customer cable end and can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment and that the connection point is lower than the
motor if possible.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
4.2.1 Requirements
;
Check whether the information on the nameplate matches the
connection data.
;
If the motor run capacitor was not installed by ebm-papst, check
whether the information on the motor run capacitor matches the
information on the nameplate.
;
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.
4.2.2 Residual current circuit breaker (RCCB)
If the use of a residual current device (RCD) is required in your
installation, only pulse-current sensitive and/or AC/DC-
sensitive residual current devices (type A or B) are
permissible. As with variable frequency drives, residual current
devices cannot provide personal safety while operating the
device.
4.2.3 Voltage control
NOTE
Current overshoots may occur if speed control is implemented
by transformers or electronic voltage regulators (e.g. phase
control). Depending on the type of installation of the device,
noise and vibration may also occur in the case of phase
control. Vibration can lead to bearing damage and thus
premature failure.
Heating-up of the motor when using voltage control must be checked by
the customer following installation in the end device.
4.2.4 Variable frequency drive
Please use a variable frequency drive only after consultation with ebm-
papst.
When a variable frequency drive is used for speed adjustment, the
maximum safe operating speed (see 3.2 Nominal data) may not be
exceeded.
