Cautions
Make certain to follow all instructions.
CAUTION: Hazard to Equipment
•
The system must be connected to 208 Vac 3-phase wye 5-wire only.
•
The inverter must be provided with an equipment ground per NEC 690.43.
•
All five circuits (L1, L2, L3, neutral, ground) must be connected and neutral
must be bonded to earth ground. Failure to do so can damage the unit and void
the warranty.
•
The ProHarvest 208V inverter has inputs for two separate DC strings. Reversal of
polarity of one or both string inputs will irreparably damage the unit. Use a
voltmeter to carefully verify that the DC inputs are correct before connecting to
the inverter DC inputs.
•
The Communications Gateway is for indoor use only.
•
In order to maintain the integrity of the watertight enclosures:
o
All connectors must be properly and fully engaged.
o
Unused connectors must be sealed using appropriate weatherproof caps.
•
Do not allow water to enter the AC or DC connectors or the warranty will be void.
WARNING: Shock Hazard
Before disconnecting DC cables, use a current clamp meter to measure the
presence of current. If current is present, cover the portion of the array affected,
according to NEC 690.18.
