4.0 METER INSTALLATION

4.1 Mounting the Meter

STEP 1: Using the appropriate sized mounting hardware, fasten the Class 1000 meter
enclosure to the selected mounting surface. The four mounting holes are centered

6.75” H x 4” W. The mounting hole spacing is identical for either the UL Type 1 or
NEMA 4X enclosure.

NOTE: Only the NEMA 4X enclosed unit is suitable for outdoor environmental condi-

tions. Units housed in UL Type 1 enclosures must only be installed in indoor
environments where it will not be affected by the elements, such as moisture
and extreme temperatures.

4.2 Main Power Board Connections

STEP 1: Install a temporary ground for ESD (Electrostatic Discharge) protection. With
all circuits de-energized, connect a temporary protective earth ground connection for
ESD protection. Prior to performing any unit wiring, be sure to discharge any static on
your person.

STEP 2: Install the Class 1000 Protective Earth Ground. Connect an earth ground wire
to the Class 1000 protective earth ground terminal screw located on the right side of
the line voltage terminal block. After installing the protective earth ground wire,
securely fasten the protective earth ground screw.

CLASS 1000 METER

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.

CLASS 1000 METER

After all conductors are connected to their respective terminal block positions and
tightened down, verify that each terminal block screw is securely fastened by gently
tugging on each conductor. Verify that no conductor wires are frayed or are shorting to
adjacent terminal block positions.

STEP 5: External Switch Mechanism/In-Line Fuse Installation.

To ensure a safe installation, the Class 1000 meter requires an external switch
mechanism, such as a circuit breaker, be installed on the Class 1000 MAINS input
wiring. The switch mechanism must be installed in close proximity to the meter and
easily reachable for the operator. This device must also be marked as the
disconnecting device for the Class 1000 meter.

Install 1/10 Amp Slow Activation in line fuses with the suitable voltage rating for each
conductor phase at the MAINS input to the meter. The fuses must be labeled to
indicate voltage and current rating as well as element characteristics. The fuse
element must be slow activating type.

STEP 6: Once the MAINS wiring is complete, replace the clear lexan protective shield
over terminal block TB1 and close the enclosure front panel. Secure the enclosure
cover using the locking mechanism. Activate the external circuit breaker or equivalent
switch to apply AC MAINS power to the unit.

The Class 1000 meter display should turn on and indicate total kWh accumulation
reading and KW load. The display will cycle between the two readings.

STEP 7: Using an AC Voltmeter, verify the input voltage readings are within the limits
specified below.

NOTE: Single Phase systems, the voltages are measured Phase to Neutral.

Meter Input Voltage

Configuration Nominal Voltage Limits (+/- 10%)

120/208V, 2 Ph, 3 Wire 120 VAC 108 to 132 VAC

120/240V, 2 Ph, 3 Wire 120 VAC 108 to 132 VAC

277V, 1 Ph, 2 Wire 277 VAC 250 to 304 VAC

Step 8: Remove power from the unit by de-energizing the external switch.
