4.4.10 Electric connection
CAUTION
Electric connection to be executed in accordance with
local requirements. Ensure compliance with the EMC
regulatory arrangements.
WARNING
Make sure the machine is suitable for connection to
the local mains. Information about the connection
voltage and frequency can be found on the
identification plate.
Use a "clean" group to connect the system, secured at
25A gL.
The control panel needs to be provided with the following
connections:
- motor cable to fan motor (connection to frequency inverter)
- PTC cable to fan motor (connection to frequency inverter)
- 7-wired cable to control box (connection to terminal block)
- mains cable to mains (connection to main switch)
The control panel has four predrilled holes in the bottom. To
connect the cables, proceed as follows.
Fig. 4.12
•
Put in the supplied cable glands in the holes.
•
Connect the cables in accordance with the supplied electrical
diagram, which can be found inside the control panel.
A: motor cable; B: PTC cable; C: cable to control box;
D: mains cable.
Motor cable and PTC cable can be concealed in cable
troughs inside fan housing.

Functioning and setting
4.5.1 Outlet nozzles
An optimum performance of the EDS is realized by a proper air
circulation. To realize this, make sure:
- to direct the nozzles at the welding fume layer without
obstruction;
- if applicable: to direct the nozzles to the section of the facility
where the highest concentration of welding fume occurs;
- to set the correct throw by regulating the airflow.
