3.6 Mounting and environmental conditions
The WebPort 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 WebPort 2001 complies with the CE-marking requirements regarding electromagnetic compatibility (EMC)
within an industrial environment.
The normal mounting position is wall mounted on 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:
3.7 Preparing the installation
The recommended free space in the cabinet for the WebPort should be at least: 50-mm wide 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 WebPort 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 WebPort 2001
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.
(*) 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.
3.8.1 Auto fuse
An auto fuse placed just after at the power input protects the WebPort 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.
