3-4 | Model 5100 HD Analyzer
General Wiring and Conduit Requirements
•
All wiring conductor ratings should be for the minimum temperature required
for the analyzer but not less that 50° C (122° F).
•
Follow all applicable electrical codes for your location.
•
Use only applicable NEMA-approved conduit fittings or cable fittings
to maintain NEMA rating. If not using a conduit entry, leave the factory
NEMA-approved plugs intact. Never leave any holes unplugged.
•
Follow proper grounding, shielding, and noise protection practices.
•
Use twisted-pair cable with an overall braided shield, or twisted-pair cable in
rigid metal conduit for all communication wiring.
•
For AC mains supply wiring, use between 12 and 14 American Wire Gauge
(AWG) or equivalent metric between 3.3 mm2 and 2.1 mm2.
•
Do not add any additional conduit entry holes.
•
The terminal blocks in the customer connection box are sized for 0.2 - 4.0
mm2 (AWG 24 - 12) wire, 1 conductor per block, torque between 0.6 nm and
0.8 nm (85.1 to 113.5 in-oz).
EMC Grounding, Shielding and Noise Protection
For EMC purposes, do not leave cable shields disconnected at either
or both ends of the cable under any circumstance.
Use twisted-pair cable in rigid metal conduit or twisted-pair
cable with an overall braided shield. All cable shields or conduits
connecting to the analyzer must be chassis-grounded.
NOTE
EMC grounding method
Shield Ring Method
Connect all shields for the conduit entry (other than power) to a supplied shield
terminal ring. Place the shield ring under the conduit nut. Crimp the shields from
all cables for the conduit entry to a female quick disconnect and then push it onto
the tab that sticks out of the conduit shield ring. Keep shields as short as possible.
Ground Stud Method
Connect all cable shields for the conduit entry hole to the grounding stud closest
to the conduit entry hole.
