SELECT THE CORRECT TYPE OF CABLE ENTRY
Before starting to install the analyzer, verify what type of cable entry is
required at your site of installation:
X-STREAM ameproof gas analyzers may be equipped with cable glands
(regulated e.g. for installations covered by ATEX) or may be installed with
conduits (e.g. in North-America).
EXPLOSION HAZARD WHEN INSTALLING CONDUITS
X-STREAM ameproof gas analyzers provide metric threads for installing
cable entries. Installing conduits requires using metric-to-NPT adaptors!
To stay compliant with the North-American certication use only ameproof
certied adaptors, e.g. the following type:
Redapt AD-U series, stainless steel with captive o-ring seals,
size male M20 x 1.5 to female
3
⁄4"-NPT or
1
⁄2"-NPT.
Select a type of conduit according the local code, suitable for above
mentioned adaptors and the site of installation.
During installation follow the instructions provided by the manufacturer of
the conduits!
Unused entries must be provided with ameproof plugs, secured in place
with thread locking compound!
EXPLOSION HAZARD WHEN ENERGIZED
Do not open instrument when energized.
Ensure that external circuitry is disconnected or de-energized before
opening the instrument.
All cables (power and signal) must end (be connected) in either a safe (non-
hazardous) area or in a protecting enclosure (e.g. Ex e junction box)!
