2.7 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP
rating
per EN60529:
IP66
Suitable for exposure to Acetone , Ammonium Hydroxide ,
Diethyl Ether , Ethyl Acetate , Ethylene Dichloride , Furfural,
n-hexane , Methyl Ethyl Ketone , Methanol , 2-NitroPropane
and Toluene.
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.

Rated at 1Hz
Table 1: Electrical Ratings
The input current will vary according to the voltage input level.
3) Special Conditions of Use
The enclosure coating is non-conductive and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions (such as high pressure steam)
which might cause a build-up of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
should be done only with a damp cloth.
Flame Path Positions
4) Installation
There are no restrictions on unit orientation.
The junction box must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive atmospheres -
Classification of areas. Explosive dust atmospheres
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
4.1 Safe Installation Requirements
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
