imity to the meter and easily reachable for the operator. This device must
also be marked as the disconnecting device for the Class 3400 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 (order “-SP” option) connections: Connect two AC
main power wires to phases A and B - Connect jumper from B to C - factory
installed
option. Verify that no conductor wires are frayed or shorting to adja-
cent terminal 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)
Screen 4 - Average current (amps) per phase
Screen 5 - Average voltage (volts) per phase
Screen 6 - Average voltage phase to phase
Screen 7 - Power factor (PF) per phase
