Operating instructions

Translation of the original operating instructions

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
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 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.

Protective earth contact resistance according to EN 61800-5-1

Compliance with the resistance specifications according to EN 61800-5-
1 for the protective earth connection circuit must be verified in the end
application. Depending on the installation situation, it may be necessary
to connect an additional protective earth conductor by way of the extra
protective earth terminal provided on the device. The protective earth
terminal is located on the housing and provided with a protective earth
symbol and a hole.

4.2.2 Supply connection and fuses

Assignment of supply cable cross-sections and their required fuses (line
protection only, no equipment protection).

4.2.3 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 < 250 mA

At the same time, the effective power in this operating state
(operational readiness) is typically < 5 W.

4.2.4 Residual current circuit breaker (RCCB)

If the use of a residual current device (RCD) is required in your
installation, only AC/DC-sensitive residual current devices
(type B or B+) are permissible. As with variable frequency
drives, residual current devices cannot provide personal safety
while operating the device. When the device power supply is
switched on, pulsed charging currents from the capacitors in the
integrated EMC filter can lead to the instant tripping of residual
current devices. We recommend the use of residual current
circuit breakers (RCCB) with a trip threshold of 300 mA and
delayed tripping (super-resistant, characteristic K).

4.2.5 Leakage current

For asymmetrical power systems or if a phase fails, the
leakage current can increase to a multiple of the nominal value.

4.2.6 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 Connection in terminal box

4.3.1 Preparing cables for connection

Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.

NOTE
Tightness and strain relief are dependent on the cable
used.

→ This must be checked by the user.
