(c) The negative (-) terminal of the conductor should match the
negative (-) terminal of inverter’s DC input.

3.3.3.4 DC Fuseholder Torque Specification
The inverter wiringbox may be assembled using fuse holders supplied by
either Sinofuse or Mersen (Ferraz Shamut). The touch safe fuse holders
have unique terminal torque values specified by their manufacturers. See
Table 3-7 for specified torque values.
NOTICE:
It is important to use a multi-meter to check the polarity of the DC
source circuit conductors to avoid any risk of reverse polarity.
WARNING:
A reversed string is not protected by the inverter and can cause
severe damage to equipment and personnel.
