PULSE OUTPUT kWH TRANSDUCERS
OPERATION
The H-8000 Series combines a microprocessor based kWh transducer and high ac-
curacy split-core in stru ment grade current transformers (CTs) in a single unit. Because
the electronics are integral to the CT(s), hard ware and installation costs are greatly
reduced. Split-core design eliminates the need to remove conductors.

VOLTAGE LEADS
Connect the leads to the three-phase source to be monitored. Input range is
208 to 480VAC.
MANDATORY FUSE PER NEC
Maximum current draw is 60 mA. Fuses provided by factory are rated 1/2A,
600 VAC, 200 KAIC.
PULSE OUTPUT CONNECTOR
Please refer to wiring diagram on page 4.
STATUS LED
The LED blinks green when the product is functioning normally. It will blink
slowly, approximately one second on, then one second o.
If the LED is red and blinking slowly, it may indicate incorrect wiring or a
power factor that is less than 0.5. If the LED is red and blinking fast the CT's
maximum current rating has been exceeded or the pulse rate switches are
incorrectly set.
PULSE RATE SWITCHES
These switches set the pulse output rate. Please refer to Figure 4 for settings.
EXTERNAL CTs (3 phase versions only)
These external CTs are permanently attached and must not be disconnected or
used with other power meters.

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 o. 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.

TROUBLESHOOTING
Problem: STATUS LED does not blink.
Solution: Check fuses and voltage connections. STATUS LED should blink
regardless of CTs, pulse output connections and DIP switch setting.
Problem: Readings seem highly inaccurate.
Solution: • Check that each CT is installed on the conductor with the
corresponding color voltage input lead attached. In most cases,
incorrect wiring will cause the STATUS LED to blink RED (slowly).
However, a Power Factor lower than 0.5 could cause the LED to blink
this way, even if the unit is installed properly.
• It does not matter which side of the CTs face towards the load.
• If current is below 7% of full scale maximum for the CT, a smaller
CT should be used for very low currents. An alternative is to wrap each
wire through each CT multiple times and divide the output reading
by the number of turns through the CT window.
• If using a single-phase CT model 8051, ensure that all 3 phases are
passing approximately the same current by testing each phase with
an amp-clamp. If phases are unbalanced, you should use the model
8053.

PULSE-RATE SELECTION SWITCHES
FIGURE 4
Problem: Meter o-line when load is switched o.
Solution: Voltage leads must be connected on the Line side of the conductor.
The power meter cannot communicate without voltage.
Problem: STATUS LED blinks red.
Solution: • If the LED blinks quickly, approximately 5 blinks in 2 seconds, either
the pulse-rate switch settings are incorrect OR the CT used is too
small. First check the switch settings. Ensure that an incorrect setting
has not been selected by comparison to Figure 4. Note that some
settings are not available on some models. If switch settings are OK,
then the CT used is too small. A CT with a larger current rating is
required.
• If the LED blinks slowly, approximately. 1 blink in two seconds,
the CTs are not installed on the correct conductors, or the loads Power
Factor is less than 0.5. The meter can accurately measure these low
PFs, but few loads operate normally at such a low power factor.
