KYZ Output
The KYZ solid-state relay output may be connected to an external pulse accumulator or
controller. Wetting voltage must be provided by the external device or circuit. The KYZ output
is designed for low-current (80 mA maximum) switching at up to 240V AC or 300V DC. The
diagram indicates typical KYZ wiring.

Control Power
Connect the power monitor to a source of 120/240V AC or 125…250V DC control power
through a user-provided disconnecting means. Provide overcurrent protection sized to protect
the wiring. The power monitor is internally protected. Apply control power only after all wiring
connections are made to the unit.
