3.6. Mounting & environmental conditions
The eWON unit has an IP31 protection grade.
It is therefore not suited for outdoor mounting.
The design of the unit is such that it has to be integrated in an enclosed electrical cabinet,
protected from excessive heat, humidity and dust. The eWON2005CD™ is complying to the
CE-marking requirements regarding electromagnetic compatibility (EMC) within an
industrial environment.
The normal mounting position is wall mounted on Omega-type DIN-rail (EN 50022).
The unit is suited to work in any other position.
The equipment will operate within specified tolerances only if the following environmental
conditions are respected:
Environment
Conditions
Ambient temperature range
-20°C to +70°C for eWON with GPRS-EDGE-HSUPA modem
0°C to +50°C for eWON with PSTN or ISDN modem
Ambient humidity
0-80% non-condensing
3.7. Preparing the installation
The recommended free space in the cabinet for the eWON should be at least:
80-mm wide x 200-mm high x 160-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 top
of the unit. Connect this screw directly to a low impedance ground.
