DC Wiring Connections

1. Make sure that the external disconnect switch is off.
2. Make sure that all wires are properly identified and marked:
• the cable from the PV to the external DC disconnect switch.
• the cable from the external DC disconnect to the Fhoton™ Drive.
3. Connect the cables from the external DC disconnect to the terminal block labeled "Solar Primary DC" and marked +, - and GND.

CAUTION
!
Only connect a photovoltaic solar array to the DC input of the Fhoton™ Drive. This controller is suitable for use on a PV circuit capable of
delivering not more than 50 DC amps short circuit current.
In this drive, the integral solid state short circuit protection of motor wiring does not provide circuit protection of wiring for input power.
Input wiring protection must be provided in accordance with all applicable national and local electrical codes. In addition, follow any
manufacturer's recommendations for protection of a photovoltaic (PV) array.
