2.7 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP
rating: IP66
Type rating per UL50E / NEMA250: 4 / 4X / 3R / 13
To maintain the ingress protection rating, the cable entries
must be fitted with suitably rated, certified cable entry and/or
blanking devices during installation.
2.8 Electrical Ratings
It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the
units.
The input current will vary according to the voltage input
level. The current levels shown above are for the worst-case
input voltage and flash setting resulting in max. current.
For detailed current ratings of the device please see Section
13.
3) Special Conditions of Use
Special Condition for safe Use as stated on the Type
Examination Certificate DEMKO 14 ATEX 4786493904X /
CoC IECEx ULD 14.0004X:
When used for a Group III application, the surface of the
enclosure may store electrostatic charge and become a
source of ignition in applications with a low relative humidity
<~30% relative humidity where the surface is relatively free of
surface contamination such as dirt, dust, or oil.
Guidance on protection against the risk of ignition due to
electrostatic discharge can be found in EN TR50404 and IEC
TR60079-32.
End user shall adhere to the manufacturer’s installation and
instruction when performing housekeeping to avoid the
potential for hazardous electrostatic charges during cleaning,
by using a damp cloth.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
