2. Terminate at fuseholders. The RSD wirebox only contains
fuseholders for the positive DC conductors. Follow instructions in
step 3 for the negative conductors. Strip approximately ½ inch of
the cable jacket from the end of the string conductor. Insert the
conductor into the fuseholder terminal ensuring the stranding of the
conductor remains firmly twisted and does not separate. Tighten the
screw clamp to the torque specified in Table 3-7. Continue
terminating the remaining strings in this manner for each MPPT
(PVIn1, PVIn2, PVIn3).
3. Terminate at busbar (RSD wirebox). The RSD wirebox only
contains fuseholders for the positive DC conductors. Follow
instructions in step 2 for the positive conductors. The negative DC
conductors are to be terminated on the busbar. Strip approximately
½ inch of the cable jacket from the end of the string conductor.
Insert the conductor into the busbar ensuring the stranding of the
conductor remains firmly twisted and does not separate. Tighten the
screw to the torque specified in Table 3-7. Continue terminating the
remaining negative DC conductors in this manner for each MPPT
(PVIn1, PVIn2, PVIn3).
4. Bypass Terminal option for standard wirebox. Fuse Bypass
Terminals are available as an optional accessory when external PV
string fused combiners are used. The Bypass Terminals allow for
larger single conductors to be terminated at each MPPT within the
wirebox, bypassing the input fuses as shown in Figure 3-25. See
Section 9 Accessories for installation information.
