KTL-DO/US-480 inverters have several optional accessories that allow the
inverter to support a wide range of real-world applications.
9.1 Fuse Bypass Terminals
The Fuse Bypass Terminals allow for a reduction in the number of DC
homeruns by combining the PV source circuits outside of the inverter wirebox
and terminating with one pair of DC inputs to each of the three MPPTs. Note
that external over current protection for the PV source circuits is required
outside of the inverter. The MPPT positive inputs IN1+, IN2+, and IN3+ are
isolated from one another by design, although the MPPT negative inputs IN1-,
IN2-, and IN3- are combined via a common bus structure. The Fuse Bypass

9.1.1 Bypass Input Terminal Instructions
1. A maximum #2AWG wire should be used to minimize stress on the
adapter.
2. Remove the wirebox cover (Figure 9-1).
3. Remove the plastic touch safe finger guards (Figure 9-2).
4. Use a No. 2 Phillips head screwdriver to install the Bypass Terminals
on each bus by fastening each terminal with the M4 screws. Torque
value of 14 in-lbs (1.6 N.m) (Figure 9-3 and Figure 9-4).
5. Use a No. 10 wrench to fasten the three pairs of DC input cables to
each of the Bypass Terminals at IN1+, IN2+, IN3+ (Figure 9-3) and
IN1-, IN2-, IN3- (Figure 9-4) with the M6 screws. Torque value of 50
in-lbs (6.0N.m.).
6. Reinstall the plastic touch safe finger guards. Torque value #
7. Reinstall the wirebox cover. Torque to 35.4 in-lbs (4N.m).
