Safety

Before installation:

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. Do not attempt to disassemble the unit. There are no user serviceable parts inside. Do not drop, knock or shake the unit, rough handling above the specification may cause

damage to internal circuit boards. Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit. Do not paint the unit. Paint can clog the unit and prevent proper operation. Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-

proof. Keep the unit within the specified humidity levels. Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical

part may be damaged. If the unit is not working properly, contact the place of purchase, nearest Westermo dis-

tributor office or Westermo Tech support. A readily accessible disconnect device shall be incorporated external to the equipment. This unit may have hot surfaces when used in high ambient temperature.

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.

Special condition for use

Ambient temperature:

This unit is designed for use in extreme ambient temperature conditions according to the following: –40 ºC ≤ T

≤ +70 ºC

amb

Installation in an apparatus cabinet:

This unit requires installation in an Ex certified apparatus cabinet suitable for the area of use and providing a degree of protection of at least IP54.

Resistance to impact:

This unit requires installation in an apparatus cabinet where adequate resistance to impact is provided by the apparatus cabinet. See "Installation in an apparatus cabinet" above for requirements on the external apparatus cabinet.

Resistance to light:

This unit requires installation in an apparatus cabinet where it is protected from light (for example daylight or light from luminaires). See "Installation in an apparatus cabinet" above for requirements on the external apparatus cabinet.

Transient protection:

This unit requires external transient protection at the power supply terminals to be set at a level not exceeding 67 VDC.

Secureness of plugs:

When this unit is installed in an explosive atmospheres, all connectors must be mechanically secured to prevent loosening.

Conductor temperature:

When this unit is installed in locations with high ambient temperature, special precautions shall be taken upon the choice of external conductor(s) and the temperature rating of the conductor(s).

Directive 94/9/EC alongside with other directives:

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.
