damaging body parts. Shields must therefore be established on both the suction and return sides in accordance
with ISO 13857.
4.2 Electrical connection
35
DANGER
Voltage on the device
Electric shock
Always connect a protective earth first
Check the protective earth
36
DANGER
Electrical charge (>50
μ
C) 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 circuitry, short the
supply and PE connections.
37 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.
38 NOTE
Electrical noise and consequent malfunction.
Provide a gap between the supply cable and the control cable when installing these in the application.
Provide adequate distance.
Recommendation: distance> 10 cm (separate wiring).
39 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.
40 Only connect the fan to circuits that can be switched off with an all-pole disconnection switch.
4.3 Requirements
41 Check whether the information on the nameplate matches the connection data.
Before connection the device, make sure the power supply matches the device voltage.
Only use cables designed for the current level indicated on the nameplate.
4.4 RCD
If your system requires the use of an FI relay, it is only permitted to use FI relays that are sensitive to all types
of current (type B or B +). Personal protection is not possible with FI relays when operating the unit, as is the
case with frequency inverters. When connecting the unit voltage supply, pulse-shaped charging currents from
the capacitors in the integrated EMC filter can cause the activation of delayed release FI relays. We recommend
fault current switches with a triggering threshold of 300 mA and delayed release (super-resistant, characteristic
K).
