6.2 Main Power Board Connections (continued)

Fig. 4. Terminal Block TB1.

NOTE: For 3-wire delta-type meters, Do NOT connect the NEUTRAL wire. Remove

the terminal block screw for this position.

a. Connect the NEUTRAL wire to the appropriate terminal block position.

b. Earth Ground: Connect the Earth Ground to the PCB mounting screw in the

lower right corner.

c. External Switch Mechanism/In-Line Fuse Installation

To ensure a safe installation, the Class 3400 meter requires an external

switch mechanism, such as a circuit breaker, be installed on the meter’s

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 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.

Verify that no conductor wires are frayed or shorting to adjacent 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
