HAZARD OF ELECTRIC SHOCK AND ARC FLASH

  • This equipment must only be installed, uninstalled and serviced by qualified electrical personnel.
  • Use appropriate personal protective equipment (PPE) and follow safe electrical work practices according to NFPA 70E or CSA Z462.
  • Equipment energized from multiple sources including PV, AC, and additional batteries. Before removing covers identify all sources, de-energize, lock-out, and tag-out and wait five minutes for circuits to discharge.
  • To turn the battery(ies) off: On all batteries, press the power button for six seconds, and turn the disconnect switch to the OFF position.
  • Verify de-energization with a voltage sensing device, rated 600 V or higher.
  • Never energize the system or turn the battery disconnect switch(es) to the ON position with the wiring or fuse access covers removed.

Failure to follow these instructions will result in death or serious injury.

Notes:

  • For the battery disconnect switch(es), use a small lock or cable padlock as the lock-out device.
  • For more information about the Schneider Inverter, see the Schneider Inverter Installation Guide (TME12664).

To lock-out and tag-out the Schneider Boost:

  1. Press the battery's power button for six seconds. Repeat for all batteries that are connected to the same inverter.
  2. Turn the Schneider Boost's battery disconnect switch to the open position O . Repeat for all batteries that are connected to the same inverter. Lock-out and tag-out the disconnect switch(es) (see Lock-Out and Tag-Out (LOTO)).
  3. Locate the external AC (grid) disconnect, and turn it to the OFF position (see Lock-Out and Tag-Out (LOTO)).
  4. On the connected Schneider inverter(s), turn the Solar disconnect switch to the open O position. Lock-out and tag-out the disconnect switch (see Lock-Out and Tag-Out (LOTO)).
  5. Wait five minutes for circuits to discharge.
  6. Open the inverter's wiring door and, using a voltage sensing device rated 600 V,
    CAT III or higher, confirm that all circuits are de-energized before performing work: Measure voltage at the PV, battery, and AC terminals in the inverter.
