Electrical Connections
The nominal operating voltage and power consumption is indicated on a
label on the front of the Ex d Lower Enclosure. Verify that the operating
voltage indicated on the label agrees with the operating voltage indicated
on the documentation supplied with the analyzer.
For Division 1/Zone 1 Installations, all cable entry glands (one
power cable entry and two signal cable entries) into the flameproof
enclosures must be Ex d certified. Conduit or cable seals that comply
with the flameproof enclosure cable entry sealing requirements of the
local authority must be installed at the entries to the enclosure. In all
cases, each unused cable entry port must be plugged with a certified
Ex d plug.
Refer to “Electromagnetic Compatibility (EMC)” near the beginning
of this manual for information about the EMC Directive regarding
techniques and wiring practices to be followed.
To maintain EMC compliance in European installations, AMETEK
recommends using metallic glands and shielded cable (at least 85 %
coverage) for both power and signal cable connections.
