Remove the terminal block and attach the pulse output wires. Positive,
negative and Shield wires must be connected as shown in Figure 3.
If necessary, insulate any exposed wiring. Ensure that insulation
complies with local and national electrical codes.
Approximate check of output:
1. Check actual current with Amp clamp.
Expected power is:
kW = Volts x Amps x 1.732 x PF ÷ 1000
kW = Horsepower x .746
2. Calculate approximate seconds per pulse:
S=kWh
Pulse Setting
seconds/pulse = 3600 x S
kW
Note: Since these calculations are approximate, there may be some
variation.
NOTES
1. DO NOT GROUND THE SHIELD INSIDE THE ELECTRICAL PANEL.
All wires, including the shield should be insulated to prevent accidental contact to high voltage conductors.
2. The cable should be mechanically secured where it enters the electrical panel.
3. The cable should be shielded twisted pair wire BELDEN 1120A or similar
WARNING: After wiring the cable, remove all scraps of wire or foil shield from the electrical panel.
This could be DANGEROUS if wire scraps come into contact with high voltage wires!
Set the switches for the desired pulse-rate as shown in Figure 4. Note that
some settings are not allowed.
Disconnect power and lock-out all power sources during installation.
DO NOT CONNECT VOLTAGE INPUTS LIVE!
Connect the voltage leads to the 3-phase conductors, as shown in Figure
2. Becaue the meter requires voltage to communicate, connect the leads to
a location which is not normally switched off. Connect the red lead to the
conductor most convieniently located to physically mount the CT with pulse
output connector. After selecting the conductor for the red lead, the black
and yellow leads may be attached to the other two conductors in any order.
Attach CTs to conductors. Each CT must be attached to the same conductor
as the correspondingly colored voltage lead. (See wiring diagram above) The
unit will automatically detect phase reversal, so it is not important to orient a
particular side of each CT towards the load.

The H8000 series is NOT intended to be connected to the load side of variable frequency drives. Damage to the unit will result from
such a connection.
