CLASS 5000 METER

c. External Switch Mechanism/In-Line Fuse Installation.
To ensure a safe installation, the Class 5000 meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Class 5000
MAINS input wiring. The switch mechanism must be installed in close prox-
imity to the meter and easily reachable for the operator. This device must
also be marked as the disconnecting device for the Class 5000 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 characteris-
tics. The fuse element must be slow activating type.
d. Connect the three AC main power wires (Phases A, B and C) to their respec-
tive positions as labeled on terminal block TB1 and tighten to 7 in-lb. After all
conductors are connected to each of their respective terminal block positions
and tightened down, verify that each terminal block screw is securely fas-
tened by gently tugging on each conductor.
NOTE: On Single phase connections: Connect two AC main power wires to
phases A and B - Connect jumper from B to C - factory installed for “-SP”
option. Verify that no conductor wires are frayed or shorting to adjacent ter-
minal block positions.
e. Turn ON the AC main power input. The meter display will light up and scroll
through 7 displays. Each display is visible for 5 seconds. Display screens are
as follows:
Screen 1 - Total kilowatt-hours (kWh) consumed
Screen 2 - Peak demand (kW) with date & time stamp
Screen 3 - Actual load (kW) with preset date & time
Screen 4 - Average current (amps) per phase
Screen 5 - Average voltage (volts) per phase
Screen 6 - Average voltage (volts) phase to phase
Screen 7 - Power factor (PF) per phase
f. Verify the voltage readings on Screen 5 using an AC voltmeter. Typical read-
ings shown below are measured phase to neutral for 4 wire and phase to
phase for 3 wire. Readings should be +/- 10% of nominal.
NOTE: Meters are powered by phases A and B. The displayed voltages will be the
measured AC voltage between phases.
