Power system wiring: iEM3100 / iEM3300 series

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not connect N’ to the load when setting the wiring type on the meter to 1PH4W Multi L-N. Failure to follow these instructions will result in death or serious injury.

1PH2W LN ≤ 240 V L-N

1PH2W LL ≤ 415 V L-L

1PH3W LLN ≤ 240 V L-N
≤ 480 V L-L

1PH multiple load with N

3PH3W ≤ 480 V L-L

3PH4W ≤ 240 V L-N
≤ 480 V L-L

Fuses and disconnect switch

Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator.

Fuses / circuit breakers must be:

Installed in accordance with all local and national electrical codes and standards.
Rated for the installation voltage, available fault current, and sized for connected loads.

Fuse for neutral is required if the source neutral is not grounded.
