Xantrex Technology PV100S-208 manual CAUTION Fire Hazard

Safety

The terminals are one bolt per pole. See the PV100S 100 kW Grid-tied Photovoltaic Inverter Planning and Installation Manual for the location of these terminals.

5.The AC power conductor wiring interfacing with the AC terminals in the Main Inverter Enclosure are located at TB4-A, TB4-B, and TB4- C. These terminals are to be tightened to a torque value of 275 in-lbs (31.1 Nm) for model PV100S-208 and model PV100S-480. The terminals will accept a conductor size of 350 kcmil. See Figure 5-1 on page 5–4for the location of these terminals.

6.The AC power conductor wiring interfacing with the AC terminals in the AC Interface Enclosure are located at S1-2T1, S1-4T2, and S1-6T3. These terminals should be tightened to a torque value of 310 in-lbs (35.0 Nm) for model PV100S-208 and to a torque value of 115 in-lbs (13.0 Nm) for model PV100S-480. See Figure 5-2 on page 5–4for the location of these terminals. Also see the cautionary note in the PV100S 100 kW Grid-tied Photovoltaic Inverter Planning and Installation Manual regarding hardware length.

7.The AC neutral conductor from the utility is terminated in the AC Interface Enclosure at the TB6-Neutral terminal. This terminal requires the use of a crimp-on type ring terminal or compression-type lug and should be tightened to a torque value of 228 in-lbs (25.7 Nm) for model PV100S-208 and model PV100S-480. See Figure 5-2 on page 5–4for the location of these terminals.

8.The DC power conductor wiring interfacing with the DC terminals at TB3-1, TB3-2, and TB3-3 are to be tightened to a torque value of 500 in-lbs

(56.5 Nm) for model PV100S-208 and model PV100S-480. These terminals will accept a conductor size of 500 kcmil. Keep these cables together as much as possible and ensure that all cables pass through the same knockout and conduit fittings, thus allowing any inductive currents to cancel. See Figure 5-3 on page 5–5for the location of these terminals.

9.This product is intended to be installed as part of a permanently grounded electrical system per the National Electric Code ANSI/NFPA 70. A copper ground rod must be installed within three feet of the PV100S enclosure. This is the single point earth ground for the inverter system. The single point ground for the system is to be made at the AC ground bus bar (TB2) in the AC Interface Enclosure. This terminal requires the use of a crimp on type ring terminal or compression-type lug and should be tightened to a torque value of 420 in-lbs (47.5 Nm) for model PV100S-208 and model PV100S-480.

10.The equipment grounds on the PV100S are marked with this symbol:

11.AC overcurrent protection for the utility interconnect (Grid-tie) must be provided by the installers as part of the PV100S installation.

CAUTION: Fire Hazard

In accordance with the National Electrical Code, ANSI/NFPA 70, connect only to a circuit provided with 400 amperes maximum branch circuit overcurrent protection for model PV100S-208 and only to a circuit provided with 200 amperes maximum branch circuit overcurrent protection for model PV100S-480.
