PRO208V-5k75 Installation and Safety Manual
Inverter Placement
The ProHarvest 208V inverter is NEMA6 rated and may be placed almost anywhere.
Cooling is most efficient if the unit is mounted vertically in the shade, bolted to
racking and with the connectors pointing downwards. However, any orientation
is acceptable. Ideal placement is at least 1" above the roof, and with 4 to 5"
clearance above the cooling fins to allow air to circulate.
Mounting hardware up to 5/16" will fit the baseplate
mounting slots.
Gateway Placement
Internet access should be provided to enable firmware updates and customer support functions.
The Gateway is rated for indoor installation only. Do not expose it to rain, extreme temperatures, or
excessive dust. It must be mounted indoors. A utility closet or similar location physically close to the
inverter system is ideal. It must be electrically connected to one of the three AC phases used by the
inverter. Note that in large utility closets it is often easy to end up on an unrelated AC circuit
accidentally, in which case communications are unlikely to be successful.
Recommended: Add a 120 Vac outlet at the earliest entry point in the building to provide the best
power line communication (PLC) signal possible. Ideally this would be a 120 Vac outlet next to the
circuit breaker.
Gateway should be protected by a 15A OCPD.
A wired Ethernet network connection must be provided to the Gateway for proper data retrieval.
If outdoor placement is required, the Gateway must be housed in a weatherproof enclosure.
The Gateway has "keyhole" mountings on its baseplate. Each hole has a
guide-hole above. It is intended that these four holes provide a template for
mounting such that a pen or center punch can be inserted through and
marks left on the wall to help accurate drilling of holes. Mounting can be
performed using #8-sized screws.
Notes on Wiring
5.3.
AC Cable
The inverter AC cable has a TC-ER rating. The "-ER" signifies that the cable is sufficiently rugged to permit its
use as exposed wiring, according to the NEC (section 336.10). Exposed wiring is wiring that is not installed in a
tray, conduit or other raceway. It must be secured every 6 feet or less and protected from physical damage.
