Inverter/Charger Installation

AUX-RPO: User Remote Power Off (RPO)

Connecting JU-2 (AUX-RPO) and JU-3 (AUX-COM) terminals together through an external switch (normal open contact) will provide the system shut off function if the switch is closed.

The external switch if pressed overrides the control provided from the front panel.

If the external switch is cleared (not pressed), the system can be enabled back from the front panel.

Select an external switch with normal open contact; consult your local system designer or qualified technician for specific installation instructions.

User Line Wiring

Use twisted pairs of #24 AWG to #12 AWG for connections. Carefully route the wires away from high power load cables to minimize noise effects on signal integrity.
