Securing the housing cover in flameproof areas
The front face of the field indicator housing features a locking screw (hex-head socket screw) on the top right-end corner.
• Install the cover on the housing by hand-tightening it.
• Turn the locking screw counterclockwise to secure the housing cover. This involves unscrewing the screw until the screw head stops at the housing cover.
IMPORTANT
For Hazardous Areas installations, at least six (6) threads on the cover must be engaged in order to meet flameproof (explosion-
proof) requirements.
