1.0 Introduction
– Zone 2 & Zone 22, Ex ec, Ex tc LED Luminaire
General
The type of protection is Ex ec and Ex tc. The Zone 2 & Zone 22 series LED luminaires are surface mounted or
suspended, utilising the two holes on the base of the body. They are mainly used in harsh environments, and are
constructed using a corrosion resistant glass reinforced polyester body, attached to an injection moulded
polycarbonate diffuser by stainless steel toggle clips.
The control gear and LED’s are mounted on a removable
tray that for maintenance purposes has hanging straps.
Note: The ratings are listed in TABLES A & B.
1.1 Application
The luminaire is designed to be safe in normal operation. The luminaire should not be used where there are
environmental, vibration or shock conditions above the normal for fixed installations. The gaskets should not be
exposed to hydrocarbons in liquid or high concentration vapour states.
The luminaire is suitable for applications where Category 3 apparatus can be used. The type examination does
not address suitability for portable applications.
2.0 Storage
Luminaires are to be stored in cool dry conditions preventing ingress of moisture and condensation.
SPECIAL CONDITIONS FOR SAFE USE
The Luminaire shall only be installed where there is a low risk of mechanical damage.
When refitting the diffuser, the fixing clamps are to be re-secured with the original or replacement self
tapping screws.
Fasteners through the enclosure used for mounting purpose shall be fitted with appropriate sealing
washers to maintain the ingress protection rating of the enclosure.
