Choose A Location For The Iq Gateway; Provide A Power Connection - enphase Envoy-S Installation And Operation Manual

1. Choose a Location for the IQ Gateway

a. Install the IQ Gateway near the switchboard. This ensures that the IQ Gateway receives the
strongest possible communications signal from each device. When installing the IQ
Gateway Metered, consider the length of the CT leads when choosing the location. If you
need to extend the CT leads, see "Extend CT Leads, If Needed" on page 16.
b. Install the IQ Gateway in a protected dry space (such as a garage, attic, basement, or other
cool, dry location). If the IQ Gateway is hard-wired outdoors, you must install it inside an
IP54-rated, (or better) enclosure with conduit attachment. Use an appropriately rated
enclosure if hard-wiring indoors.
NOTE: Metallic enclosures may impair Wi-Fi signal strength.
c. Mount the IQ Gateway horizontally using the included DIN rail.
WARNING: Risk of equipment damage. When installing the IQ Gateway in an
enclosure, choose area for installation where ambient temperature does not exceed
46º C.
d. To wall-mount, use two appropriately sized screws and a screwdriver. Mount the DIN rail
first, and then clip the IQ Gateway to the DIN rail.

2. Provide a Power Connection

The IQ Gateway Metered (ENV-S-EM-230) uses terminal blocks for power and metering connections.
It does not include an AC power cord, and you must hard-wire it. When you hard-wire the IQ
Gateway outdoors, you must install it in an IP54-rated, or better enclosure with conduit attachment.
Use an appropriately rated enclosure if hard-wiring indoors.
DANGER! Risk of electric shock. Be aware that installation of this equipment includes
risk of electric shock. If you wire the IQ Gateway at the sub-board, always de-energise the
sub-board before beginning wiring.
a. Depending on the number of phases you will wire, use a one-, two-, or three-pole (20 A
maximum) circuit breaker for the supply wiring.
b. Make sure supply wiring is 2.5 mm
c. Locate the screw on the terminal block door, and loosen it with a screwdriver to unlock the
door and flip it open.
d. Depending on the number of phases to wire, connect Line 1 to L1, Line 2 to L2, Line 3 to L3,
and Neutral to N, as required.
e. Tighten all connections to 0.56 Nm.
f. Refer to the following wire colour table, if needed:
