Note 2. Wiring
• In hazardous locations, the cable entry devices shall
be of a certified flameproof type, suitable for the
conditions of use and correctly installed.
• Unused apertures shall be closed with suitable
flameproof certified blanking elements. (The plug
attached is certificated as the flame proof IP67 as a
part of this apparatus.)
• In case of ANSI 1/2 NPT plug, ANSI hexagonal
wrench should be applied to screw in.
