Uninstall the Inverter

Uninstall the inverter and wiring box assembly according to the following steps when the inverter needs to be
removed:
 Turn off the external AC breaker and/or system disconnect switch using lock-out/tag-out procedures.
 Turn off the external DC breaker and/or disconnect switch, if present, and use lock-out/tag-out
procedures. (Skip this step if there is no DC circuit breaker.)
 Switch the inverter's AC disconnect switch to "OFF" position.
 Switch the inverter's DC disconnect switch to "OFF" position.
 Wait for 5 minutes to ensure the internal capacitors have been completely discharged.
 Measure the AC output conductor terminal voltage against the ground. The meter should now read 0V.
 Disconnect the AC and EGC cables referring to "4.3.4 Electrical Installation AC".
 Disconnect the DC cables referring to "3.3.3 Electrical Installation DC".
Energized conductors
If PV strings terminate directly into the wiring box and do not pass through a breaker or switch that was
•
opened in Step 2 of Section 9.2 Uninstall the Inverter, these homerun conductors may be energized.
 Uninstall the inverter by reversing the installation steps found in section 4.2 Mechanical Installation
10.

Accessories

The Yaskawa Solectria Solar PVI 25TL-208, PVI-36TL-480-V2, PVI 50TL-480, AND PVI 60TL-480 inverters have
several optional accessories that allow the inverter to support a wide range of real-world applications.

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 wiring box 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 Terminals MTLSR-070553 for the
PVI-36TL-480-V2, PVI 50TL-480 and PVI 60TL-480 models only. For the PVI 25TL-208 inverter, please contact us
about options.
Bypass Input Terminal Instructions
1. A maximum #2AWG wire should be used to minimize stress on the adapter.
2. Remove the wiring box cover (Figure 10-1).
3. Remove the plastic touch-safe finger guards (Figure 10-2).
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 10-3 and Figure 10-4).
