Read this manual completely and gather all information on the unit. Make sure that
you understand it fully. Check that your application does not exceed the safe operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.

SPECIAL
CONDITION
Equipment group II.
This unit can be installed in all places with an explosive gas atmosphere other
than mines susceptible to firedamp.
Equipment category 3.
A category is the classification according to the required level of protection.
This unit ensures the requisite level of protection during normal operation and
is intended for use in areas in which explosive atmosphere caused by gases,
vapours, mists, or dust mixtures are unlikely to occure or, if they do occure, are
likely to do so only infrequently and for a short periode only.
Indicates protection concerning explosive atmospheres caused by gases,
vapours or mists (G).
The type of protection used.
This unit is a non-sparking device "nA" which is constructed to minimize the risk
of occurence of arcs or sparks capable of creating an ignition hazard during
conditions of normal operation.
Temperature class T4 (T4 = 135 °C).
This unit is classified in accordance with its maximum surface temperature
(external and internal).
Equipment protection level Gc (EPL Gc).
Equipment for explosive gas atmospheres, having a "enhanced" level of protection, which is not a source of ignition in normal operation and which may have
some additional protection to ensure that it remains inactive as an ignition
source in the case of regular expected occurences.
EPL Gc are analogous to the ATEX Categories (Category 3 G = EPL Gc).
This unit has a special condition for safe use.
The special condition for safe use contains safety related information that is
necesarry for the correct installation and safe use.

Directive 2004/108/EC (EMC) applies and to assure a safe performance of this unit
under the scope of Directive 94/9/EC, refer to the electromagnetic immunity level
specified under “Type tests and environmental conditions” in this manual.
Warning marking:
When this unit is installed in an explosive atmospheres, the warning label submitted
together with this unit shall be attached on the unit and visible to the end user.
