Rapid Shutdown Combiner Installation and Operation Guide (Rev B)
DOCR-070566-B
DANGER
-To ensure maximum protection against hazardous voltages while
assembling PV installations, both the positive and the negative conductors must
be strictly isolated electrically from ground as well as each other.
WARNING
- Always de-energize the AC branch circuit before servicing. Never
disconnect the DC connectors under load.
WARNING
- Install the RSD Combiner within 10 feet of the array per 2014 NEC
requirements.
CAUTION
- Despite having a Type 4X enclosure with a pollution degree II
certification, the RSD Combiner must not be exposed to heavy soiling.
CAUTION
- Unused connectors and holes must be covered with sealing
connectors and plugs.

Mounting the RSD combiner
Fig.4 Mounting SOLECTRIA RSD Combiner
Mount the RSD Combiner under the PV module, away from rain and sun. Do not
mount the RSD Combiner in a position that allows long-term exposure to direct
sunlight or in a vertical orientation that allows water to collect in the DC connector
area.
Tighten the RSD Combiner fasteners to a torque of 45-50 in-lbs (5 Nm) for 1/4’’ (6
mm) hardware and 80-85 in-lbs (9 Nm) for 5/16’’ (8 mm) hardware. Do not over
torque. All three mounting locations should be used to support the RSD to the
rail. Use suitable hardware for the racking system used.
