Add Breakers as Needed
You can install 10A, 15A, or 20A breaker(s) in the IQ Combiner+ or the IQ Combiner 3:
• BRK-10A-2-240V
• BRK-15A-2-240V
• BRK-20A-2P-240V
The combiner includes one two-pole 10A circuit breaker that feeds the IQ Envoy and the AC outlet (if present). You can install additional breakers,
if needed. You must follow all NEC and local electrical codes. To install a breaker:
A ) Check that the IQ Combiner is de-energized.
B ) Flip the breaker to the off position.
C ) Loosen the screws on the deadfront and remove the deadfront.
D ) Remove a filler plate from the deadfront for each breaker position you will use. To remove the filler plate, press the single latch inward while
gently pushing the filler plate out.
E ) Install the breaker by rocking it to the left, catching the clips that hold it in place. Then rock the breaker to the right so it is fully seated and
secure.
F ) Wire the conductors to the circuit breaker(s) as specified on the combiner box wiring label.
G ) Tighten the breaker connections to 2.2 Nm (20 in-lb).
H ) Re-install the clear plastic deadfront, aligning the deadfront screws with the screw holes in the combiner. Start each screw, then go back and
fully tighten each of the screws.
I ) Position the deadfront, aligning the deadfront screws with the screw holes in the combiner. Start each screw, then go back and fully tighten
each of the screws.
J ) Flip the breaker to the on position.
