Wiring Solar Power Conditioner - Sharp JH-3500U Installation & Operator's Manual

Wiring Solar Power Conditioner

WARNING
• All the procedures must be performed by a certified installer.
• Wiring the solar power conditioner and the DC disconnect enclosure, or the AC load center (or the AC disconnect enclosure)
must be performed with conduit. Also, the wiring of the solar power conditioner to the solar power conditioner display
should be safe from abrasion, moisture, heat, UV, and other elements of risk.
• Completely cover the surface of the entire PV array with an opaque (dark) material before wiring the solar modules. The PV
array produces electrical energy when exposed to light and could create a hazardous shock condition.
• Do not operate with wet hands or when the body is wet, or on a wet surface. It may cause an electrical shock.
• Use low-voltage protective glove.
• Disconnect the PV array output cable and the module output cable when operating, or wear electrically insulated gear.
• Be sure to turn off the following before starting wiring; otherwise it may cause an electrical shock:
· the entire input breaker
· the dedicated breaker for the solar power conditioner on the distribution board
· the DC disconnect switch
· the dedicated breaker of the AC load center
· the AC disconnect switch
• Do not turn on the DC disconnect switch until the wiring operation is finished, and starts the operation of the solar power
conditioner.
CAUTION
• Unused cable opening must be capped to keep the enclosure watertight.
• Grounding operation is the responsibility of the certified installer.
• To avoid risk of fire or electrical shock, select proper insulation and size for wires .
• To reduce the risk of short circuits during installation or servicing of the solar power conditioner, use insulated tools.
NOTE
• All electrical installations shall be done in accordance with all local electrical codes and the National Electrical Code (NEC),
ANSI/NFPA 70.
• Use the cables of the designated size. The cables should be single copper conductor wires with a nylon jacket, and the
temperature rating of the cables should be more than 90°C with UV resistant coatings.
· Use AWG 10(or 12), for the AC cable between the solar power conditioner and the AC disconnect.
· Use AWG 12(or 14), for the DC cable between the solar power conditioner and the DC disconnect.
· Use AWG 10, for all grounding cables.
• Be sure to use a ring terminal or a fork terminal when connecting to the terminal with multi-stranded wire.
• Because of voltage drops and other considerations, larger sized cable (up to AWG10) are available.
The solar power conditioner has five cable openings (for 3/4" conduit) and their caps. Up to three openings can be
used for the connection with the DC disconnect enclosure, and one opening for the connection with the AC load center (or AC
disconnect enclosure). And wiring of the solar power conditioner and the solar power conditioner display uses an opening (for 3/4"
conduit). Unused openings must be capped to keep the enclosure watertight.
