DANGER
Risk of fatal injury due to electric shock
Severe injuries or death will result if the live connections are touched. When there is irradiance, DC voltage
is present on the open ends of the DC leads.
› Do not touch the open ends of the leads.
› Avoid short circuits.

Connecting the PV array
↻ You must remove the gland plate and have holes fabricated to the dimensions of the desired trade size knock outs
from 1/2” to 1”. The XP10U inverter is NEMA 4 rated. KACO requires that you use UL 514B watertight conduit connec-
tion at the conduit entrance.
1. Strip DC circuit conductors 3/5” per (see chapter 7.3 on page 20)
2. Route the DC circuit conductors to the DC terminals.
3. Connect the DC circuits to the PCB terminals, and in accordance with the PCB labeling.
» The inverter is connected to the PV array.
