3.7 Preparing the installation

The recommended free space in the cabinet for the eWON® on the wall for the eWON1002™ should be at least: 80-

mmwide X 225-mm high X 200-mm deep (terminal block excluded). A piece of rigid DIN-rail profile (flat 35mm wide) of suitable length should be firmly fastened, horizontally, in the middle of the area.

Grounding the eWON® is necessary to eliminate unwanted transients (lightning protection) and to conform to the EMC requirements. Therefore, a ground screw is available at the back of the unit just below the DIN latch. Connect this screw directly to a low impedance ground.

3.8 Specifications for external power supply selection

The eWON500™ eWON2001™ eWON4001™ eWON4002™ has to be supplied by an external voltage source ranging from 12 to 24 VDC. The power supplied must be SELV-compliant (security voltage) and limited in current to a max of 300mA. The safety voltage power supply is not part of the delivery. The data given below is intended to allow correct selection of the external power supply.

Table 4: Specification for external power supply selection

(*)Properly ground the unit with the earth screw at the bottom of the unit. This is a must to ensure the security and the electromagnetic compatibility (EMC) of the device.

3.8.1Auto fuse

An auto fuse placed just after at the power input protects the eWON® devices against short circuits. This component returns by itself to its normal state when the short circuit has disappeared and after the component has been cooling down. Would this fuse happen to operate, please check the device for presence of loose metal parts inside likely to generate a short circuit. If the problem recurs even after such a verification, then return the device to the vendor for further investigation.
