5. WIRING INSTRUCTIONS
5.1 Wiring Connection Guidelines
5.1.1 Cable Lead-in Fitting
(1) The pressuretight packing furnished constitutes
part of the flameproof construction. Do not
attempt to use any pressuretight packing
other than those furnished. The pressuretight
packing union should be tightened securely
upon completion of connections.
(2) This instrument is designed for use with
a flameproof external lead-in, conforming
to the lEC compatibility requirements for
pressuretight packings. Accordingly, do not
attempt to use pressuretight packings other
than those furnished.
To accommodate varying finished O.D. of the
cable, three different packings are furnished.
Select one that best fits your application. (Of
the pressuretight packings φ9, φ10 and φ11, a
φ11 pressuretight packing is factory installed
in place.)

Precautionary Notes on Cable Lead-in (pressuretight packings), both explosionproof and non-
explosionproof models:
●
Use a pressuretight packing that fits the finished cable O.D.
●
Tighten up positively to allow no clearance between the pressuretight packing and the cable.
●
If a pressuretight packing is not used, apply some waterproof treatment to preclude any chance of
moisture getting into the equipment.
