enphase Q Relay Installation

SAFETY
IMPORTANT SAFETY INSTRUCTIONS.
SAVE THIS INFORMATION.
Follow all safety and assembly instructions when installing the
Q Relay.
Safety Instructions
DANGER: Risk of electric shock. Risk of fire. Do not
+
attempt to repair the Q Relay; it contains no user-ser-
viceable parts. Tampering with or opening the Q Relay
will void the warranty. Warranty void if cover removed. If
the Q Relay fails, contact Enphase Customer Support for
assistance (http://enphase.com/global/contact/).
DANGER: Risk of electric shock. Always open or discon-
+
nect circuit from power-distribution system (or service) of
building before installing or servicing the Q Relay.
DANGER: Risk of electric shock. Do not use Enphase
+
equipment in a manner not specified by the manufac-
turer. Doing so may cause death or injury to persons, or
damage to equipment.
DANGER: Risk of electric shock. Be aware that installa-
+
tion of this equipment includes risk of electric shock. If
you wire the Q Relay at the sub-board, always de-energise
the sub-board before beginning.
+ DANGER: Risk of electric shock. Risk of fire. Only qualified
personnel should troubleshoot, install, or replace the Q
Relay.
WARNING: Before installing or using the Q Relay, read
*
all instructions and cautionary markings in the technical
description and on the Q Relay.
WARNING: Risk of equipment damage. When installing
*
the Q Relay in an enclosure, choose an area for installa-
tion where ambient temperature remains between -40º
C and 50º C.
✓
NOTE: Perform all electrical installations in accordance
with all national and local electrical codes.
✓
NOTE: Install a residual current circuit breaker if required
by national regulations.
✓
NOTE: To ensure optimal reliability and to meet warranty
requirements, the Enphase Q Relay must be installed
according to the instructions in this guide.

PREPARATION
In Enphase installations, the single-phase Q Relay (network system relay
controller) acts as a galvanic disconnection device. It is designed for single
phase use and has built in contactors. During specified grid abnormalities,
the Q Relay disconnects the Enphase Microinverters from the AC grid, and
when the voltages return to normal and the grid frequency is in the accept-
able range, the Q Relay reconnects the microinverters to the AC grid. The
Q Relay has built in current sensing that can detect DC current injection
required by VDE V 0126-1-1 requirements.
The Q Relay works together with the Envoy-S to meet the need to
break both line and neutral per grid requirements. See full installation
instructions for the Enphase Envoy-S and/or Enphase Microinverters at:
enphase.com/support.
It is best practice to install the Q Relay when installing the Envoy-S and
before commissioning the system.
The Q relay is IP-20 rated. You must mount it in an environmentally pro-
tected enclosure. Typically this is a switchboard.
