PN 903-8797, Rev A
The AC power connections are made at the terminals designated “AC Ground”,
“AC Neutral”, and “AC Line” within the Ex d Electronics Enclosure (Figure 2-3).
Note that the input sides of the three fuse holders are jumpered together via
the bus bar. The three “Neutral” terminals are also jumpered together.
The AC electrical supply wires enter the Electronics Enclosure through the
Power Cable Entry on the top of the Electronics Enclosure (Figure 2-1).
Each unused cable entry port must be plugged with a certied
Ex d plug. The plugs are supplied by AMETEK. Do not replace these
plugs with uncertied plugs.
North American Installation
• The AC electrical supply wires are typically routed through conduit (com-
plete with connector and seal) that must be approved by local wiring
regulations and electrical code for the hazardous location.
• Thread adapters are supplied with the analyzer. In the Electronics Enclo-
sure, these adapters connect the M25 threaded holes to the 1/2" and 3/4"
NPT threads that are normally used for conduit.
European Installation
To maintain EMC compliance in European installations, AMETEK
recommends using metallic glands and shielded cable (at least 85 %
coverage) for both the power and signal cable connections.
• The AC electrical supply cable must be approved by the local wiring regu-
lations and electrical codes for the hazardous location, and must be rated
for minimum 80 °C (176 °F).
Use only certied Ex d cable glands (in the Electronics Enclosure).
