AC Power and Signal Connections
Remove AC mains power from the controller before making any electri-
cal connections.
Connections to the analyzer unit are made through the
Wiring
board. The
Wir-
ing
board is located on the front-bottom of the analyzer (Figure 2-7).
Any screw terminals on the
Wiring
board not described in this section
are reserved for future use.
General Wiring and Conduit Requirements
This section discusses mandatory EMC grounding, shielding, and noise protec-
tion requirements.
• Analyzer wiring conductors must be rated at a minimum of 80 °C. All other
wiring conductor ratings should be for the minimum temperature required
for the equipment being connected to the analyzer, but not less than
60 °C.
• Use only the applicable NEMA-approved conduit fittings or cable fittings
to maintain the NEMA rating for the analyzer enclosure or WDG-V UOP. If
not using a conduit entry, leave the factory NEMA-approved plugs intact.
Never leave any holes unplugged.
• Follow all applicable electrical codes for your location.
• Follow proper grounding, shielding and noise protection practices as de-
scribed in this section.
• For all analyzer and signal wiring use twisted-pair cable, 18 to 22 AWG
(0.82 mm2 to 0.33 mm2), with an overall braided shield, or twisted-pair
cable in rigid metal conduit.
• 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.
• Use the conduit entry point closest to the connections you are making.
Do
not add any additional conduit entry holes.
