2.3.3REPO Connection

The Nfinity is equipped with a Remote Emergency Power Off (REPO) connection.

NOTE

A jumper is factory installed between pins 1 & 2 to disable the Control Switch (SW2). This will prevent the unit from being started during installation. This jumper must be removed in order to start the unit.
