DC Input Power
Input Connector and Cables
The XDI input connector is a 2-pole, double lug terminal block with
separate double studs for the ground connection. A minimum of 6 AWG
copper conductor (rated 85°C minimum) is the recommended wire gauge
for all three input cables.
DC Input Wire Connection
The DC input wiring should be routed through a 60 A circuit breaker for
each inverter used. This provides additional disconnect options and adds
to safety. A 2-pole breaker is recommended, but should a single pole be
used, it should be mounted in the negative side of the input wiring.
To connect DC input wires from the breaker:
1. Ensure DC breaker is de-energized.
2. Strip 7/16 in. (11 mm) off the positive, negative and ground cables
and install a standard two hole compression lug (hole diameter:
0.25 in. (6 mm)) on each cable.

• T&B part #: 54205
• Hendry part #: 06117-01
3. Remove the supplied nut and washer on the ground studs and install
and secure the ground connection.
CAUTION
The inverter will operate from a DC source in the range of -40 V to -60 V. The
maximum voltage without damage to the unit is -80 V. The source and cabling
shall be capable of supplying 45 A continuously for a worst case operating
voltage of -40 V. Under overload conditions (maximum 3 kW) the source
requirement will be 90 A at -40 V
Important: The following procedure should be used as a guide only. Ensure
that the installation complies with the specific wiring rules applicable to your
country or area of jurisdiction.
