Note: Before wiring, see fuse recommendations on page 22.
Follow these steps to derive control power from phase PT inputs:
1. Connect the Va terminal (terminal 9) to the L1 terminal (terminal 6).
2. For L-N control power (see figure 5-6, page 27), connect the Vn
terminal
(terminal 12) to the L2 terminal (terminal 7). For L-L control power (see
figure 5-3, page 24), connect the Vb terminal (terminal 10) to the L2
terminal (terminal 7).
3. If all wiring is complete, snap the terminal shield into the closed position.
GROUNDING THE POWER METER
For optimal grounding, connect the power meter to a true earth ground.
To ground the power meter, follow these steps:
1. Connect the ground terminal (terminal 8) to a true earth ground, using
#14 AWG wire.
2. After grounding, snap the terminal shield into the closed position.
Note: The power meter must be grounded as described in these instructions.
Failure to properly ground the power meter may induce noise on the power
conductor.
