8. DISCONNECTING FROM VOLTAGE SOURCES
Before proceeding any operations on inverter, please disconnect the
inverter from all voltage resources as described in this manual.
Following these steps in described sequence are mandatory.
1.
Disconnect miniature circuit-breaker and prevent from unintentional
reconnections.
2.
Open the DC switch and prevent the switch from closing
unintentionally.
3.
Use clamps to ensure there is no electrical current in DC wires.
4.
Disconnect all DC connections and resources. Unplug the DC
connectors, and DO NOT pull the cables.
5.
Use multimeter to ensure the voltage on DC terminals of inverter is 0.
6.
Unscrew and remove the AC connector.
Danger to life due to high voltages.
Inverter capacitors need 5 minutes to be completely de-
energized. When an error occurs, DO NOT remove the cover of the
inverter onsite. Improper operations and attempts may induce
electric shock.
