6.3.1
Selecting cables
Take the following criteria into account when selecting the connecting cables for the auxiliary
circuits:
● Rated current
● Rated voltage
● System-dependent conditions, such as ambient temperature, routing type, cable cross-
section as defined by required length of cable, etc.
● Requirements according to IEC/EN 60204‑1
6.3.2
Connecting an external fan
Preconditions
● Only use cables that comply with the relevant installation regulations regarding voltage,
current, insulation material, and load-carrying capacity.
● Before connecting the device, make sure that the line voltage matches the device voltage.
● Check whether the data on the fan rating plate matches the connection data.
● Cable glands are not included in the scope of supply. Close unused cable entries,
otherwise, the degree of protection is not maintained.
● The line voltage corresponds to the quality attributes laid down in DIN EN 50160 and the
defined standard voltages laid down in DIN IEC 60038.
Procedure
1. Open the terminal box of the external fan and route the cables into it. The cables are not
included in the scope of supply.
2. Connect the protective conductor (PE).
3. Connect the other cables to the relevant terminals, refer to the connection diagram in the
terminal box.
Connection cables must not be subject to excessive tensile stress.
Note
For fans equipped with EC motor, the fan motor starts with a delay after the line voltage is
connected.
