4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Cutting and crushing hazard when removing fan from
packaging
→ Carefully remove the device from its packaging, by the
guard grille. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ The fan must not be subjected to force or excessive vibration
from sections of the installation.
→ If the fan is connected to air ducts, the connection should
be isolated from vibration, e.g. using compensators or similar
elements.
→ Ensure stress-free attachment of the fan to the
substructure.
;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.
●The fan must not be strained on fastening.
4.2 Electrical connection
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.
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 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.
NOTE
Cable routing
→ Always route cables downward so that no condensation can
run along the cable toward the motor.
4.2.1 Requirements
;Check whether the information on the nameplate matches 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.
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.
●The values are typically in the range < 50 mA
●At the same time, the effective power in this operating state
(operational readiness) is typically < 2 W.
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 Plug connection
4.3.1 Preparing cables for connection
The cables, including the customer interface, are subject to the
specifications for internal wiring.
Ensure conformity with applicable standards and check the
degree of protection in the final product after installing the ebm-
papst device.
;Connect the cables to the mating connectors.
4.3.2 Making supply connections
;Check your connector's pin assignment.
;Connect the built-in connector with the mating connector.
;Ensure that the connector is properly engaged.
