9.1 Connecting to the Pulse Output Terminals
WARNING: TO AVOID FIRE, SHOCK OR DEATH , turn off all power supplying equipment before
working on or inside the equipment. Use a properly rated voltage sensing device to confirm
power is off.
1. Install meter as outlined in Section 3.
2. Communications cable shall enter at the TOP side of the enclosure as shown in Figure 12.
Replace plastic cap with webbed bushing (provided).
3. Use shielded twisted-pair cable to prevent interference and connect to the 6-pin removable
terminal block as shown in Figure 19. Two pins provide 10 watt-hour and 1 kWh pulse
rates. Pulses at these terminals are positive (+) with respect to the shared common
(“COM”) terminal (-), and represent energy delivered (from grid). Do not over-tighten the
terminal screws. Both pulse outputs are electrically isolated from input power and can be
used independent of one another or simultaneously.
4. Before energizing the meter close and secure the enclosure door.
