Xantrex Technology PV100S-208 manual Lockout and Tag

Maintenance Safety

Lockout and Tag

Safety requirements mandate that this equipment not be serviced while energized. Power sources for the PV100S must be locked-out and tagged prior to servicing. Each energy source should have a padlock and tag installed on each energy source prior to servicing.

WARNING: Shock Hazard

Review the system schematic for the installation to verify that all available energy sources are de-energized. DC bus voltage may also be present. Be sure to wait the full 5 minutes to allow the capacitors to discharge completely.

The PV100S can be energized from both the AC source and the DC source. To ensure that the inverter is de-energized prior to servicing, lock out and tag the PV100S using the following procedure.

1.Open, lockout, and tag the incoming power at the utility main circuit breaker.

2.Open, lockout, and tag the AC Disconnect Switch (S1) on AC interface assembly. See Figure 1-8 on page 1–12for the location of the AC Disconnect Switch.

3.Open, lockout, and tag the DC Disconnect Switch (S2) on DC interface assembly. See Figure 1-8 on page 1–12for the location of the DC Disconnect Switch.

4.Using a confirmed, accurate meter, verify all power to the inverter is de- energized. A confirmed, accurate meter must be verified on a known voltage before use. Ensure that all incoming energy sources are de-energized by checking the following locations.

a)Inverter Terminals: TB4-A, TB4-B, TB4-C (Phase A, B, C) See Figure 5-1 on page 5–4.

b)Utility Terminals: Top of S1-2T1, S1-4T2, S1-6T3 See Figure 5-2 on page 5–4.

c)PV Terminals: Bottom of TB3-1, TB3-2, TB3-3 (PV+, PV-, GND) See Figure 5-3 on page 5–5.
