CLASS 1000 METER
9 62-0388-01
WARNING
Failure to attach the protective earth ground wire securely to the enclosure
creates a potential shock hazard. Do not operate the Class 1000 meter without
a protective earth ground connection securely installed
STEP 3: Wire Entry: Two openings exist on the unit enclosure, one for 1/2” conduit and
one for 3/4” conduit. The 3/4” conduit opening located on the bottom of the enclosure
is used to bring in MAINS Power (voltage lines to power meter) and current sensor
wiring. The 1/2” conduit opening located on the top of the enclosure is used to
interface low voltage signals, such as the IDR interface and isolated pulse output.
(Outdoor enclosures equipped with one 3/4” conduit opening on bottom of enclosure
only.)
Route the appropriate cabling to and through the respective enclosure opening. The
conduit and fittings interfacing the enclosure entrances must be UL listed and properly
sized to the enclosure port diameter, The interfacing fitting must use a gasketed seal
ring to interface between the conduit fitting and the enclosure entry point. After
installing the conduit fitting and conduit, verify that the conduit fittings are aligned
properly to their respective enclosure entrance ports and tightened securely to prevent
moisture entry. VERIFY that each conduit slip nut is securely tightened to its respective
conduit fitting.
Outdoor applications require the use of the optional NEMA 4X enclosure. The same
principles outlined for indoor meter installations as defined in the above paragraph
carry over and apply to outdoor installations with one exception. This exception is that
the conduit and fittings for outdoor installations require an outdoor material rating and
UL approval for 4X applications
STEP 4: Unit MAINS Wiring (Voltage Wiring Connections) : Remove the shield located
over phase A, B and C screw terminals on the main power board. This shield can be
removed by pulling back on the latch on the right side of the shield and lifting up on the
front. Wire each connection to the terminal block with stranded wire 14-12 AWG, rated
at 600 VAC.
Strip back all wire insulation to expose between 1/4”to 3/8” of the copper conductors.
Gently twist each wire to prevent fraying. Insert the conductors into their respective
terminal block position and tighten down the terminal block screw to 7 in-lb of torque.
The terminal block is clearly labeled PHASE A, PHASE B, PHASE C and NEUTRAL.
Phase C is not used on single phase circuits.
Connect the NEUTRAL wire to the appropriate terminal block position.
Connect the AC mains power wires (Phase A and Phase B) to their respective
positions as labeled on the terminal block. Also connect the neutral wire.
