2. Provide a Power Connection
When you hard-wire the IQ Envoy, you must install it in a ventilated, NRTL certified NEMA type 3R-rated (or
better) enclosure with conduit attachment.
The IQ Envoy uses terminal blocks for power and metering connections. You must install one solid-core
current transformer (CT) for revenue-grade production metering. Consumption monitoring is optional and
requires that you order and install two additional split-core CTs. Use a protected route in conduit for the CT
wires from the main load center to the IQ Envoy. The consumption CT leads are 13 feet long. If you need to
extend the leads, refer to page 16. Do not extend the leads of the production CT.
DANGER! Risk of electric shock. Always de-energize circuits before wiring for power and CTs.
a. Use a two-pole circuit breaker of up to 20 A (maximum) for the supply wiring.
b. Make sure supply wiring is 12 to 14 AWG copper rated at 75° C or better.
c. Use a screwdriver to loosen the screw on the terminal block door and open the door.
d. Flip open the terminal block door and wire the line and neutral conductors as shown: Connect Line 1
to L1, Line 2 to L2, and Neutral to N. Tighten to 10.5 in-lbs.
