Verification Procedure Summary

WARNING: Electrocution Hazard

This chapter describes specific steps to ensure the installation of the PV100S 100 kW Grid-Tied Photovoltaic Inverter is correct and complete. Failure to adhere to these warnings could result in severe shock or possible death. Exercise extreme caution at all times to prevent accidents. These installation instructions are for use by those familiar and skilled with high voltage procedures.

WARNING: Shock Hazard

The PV100S enclosures contain exposed high-voltage conductors. The enclosure doors should remain closed with the latches tightened, except during installation, maintenance or testing. To reduce the risk of electric shock, do not perform any servicing other than that specified in the installation instructions unless you are qualified to do so.

WARNING: Lethal Voltage

In order to remove all sources of voltage from the PV100S, the incoming power must be de-energized at the source. This may be done at the utility main circuit breaker and by opening the AC disconnect and the DC disconnect switches on the PV100S. Review the system configuration to determine all of the possible sources of energy. In addition, allow 5 minutes for the DC bus capacitors, located on the ceiling of the cabinet, to discharge after removing power.

The following procedures are intended to verify correct installation and proper wiring of the PV100S. Prior to performing the following verification steps on the PV100S, review all safety requirements and procedures outlined in this manual and on any cautionary markings on the components within the system.

Inspect the following items prior to completion of the installation:

1.Visually inspect all the mechanical connections. This would include both electrical conduit fittings, as well as enclosure anchoring and seismic bracing if required.

2.Visually inspect the electrical connections and verify proper tightness of all terminations.

3.Visually inspect the Isolation Transformer Wye/Wye connections and ensure the T6-X0 neutral connection is left disconnected or floating.

4.Perform corrective actions if required.
