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 re. Do not attempt to re-
pair the Q Relay; it contains no user-serviceable 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 disconnect circuit
from power-distribution system (or service) of building and PV
side before installing or servicing the Q Relay.
+
DANGER: Risk of electric shock. Do not use Enphase equipment in
a manner not specied by the manufacturer. Doing so may cause
death or injury to persons, or damage to equipment.
+
DANGER: Risk of electric shock. Risk of re. Only qualied person-
nel should troubleshoot, install, or replace the Q Relay.
+
DANGER: Risk of electric shock. The Q Relay is intended for in-
stallation in an electrical enclosure (i.e. switchgear) that prevents
Operator access to hazardous live parts.
*
WARNING: Before installing or using the Q Relay, read all instruc-
tions and cautionary markings in the technical description and on
the Q Relay.
*
WARNING: Risk of equipment damage. When installing the Q Re-
lay in an enclosure, choose an area for installation where ambient
temperature remains between -40º C and 50º C.
*
WARNING: The temperature of the terminals may exceed 60º C.
Use an appropriately temperature-rated cable to connect to the
terminals.
*
WARNING: The circuit breaker must be suitably located and easily
reached. It must also be marked as the disconnecting device for
the PV system.
✓
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 require-
ments, the Enphase Q Relay must be installed according to the
instructions in this guide.
