Step 7: Connecting the DC Cables
Follow the procedure given below to connect the battery leads to the terminals on
the DC end. The cables should be as short as possible and large enough to handle
the required current, in accordance with the electrical codes or regulations
applicable to your installation. <Xref>Table 3-2 on page 7 specifies the minimum
DC cable size and maximum fuse size for the PROsine.
Do not route your DC cables through an electrical distribution panel, battery
isolator, or other device that will cause additional voltage drops.
Figure 3-7 shows the DC end for your reference.
CAUTION
Before making the final DC connection, check cable polarity at both the battery and the
PROsine. Positive must be connected to positive; negative must be connected to negative.
Reversing the positive and negative battery cables will damage the PROsine and void your
warranty. This type of damage is easily detected.
WARNING: Fire hazard
Use only copper wire rated 75°C minimum. Make sure all DC connections are tight to a
torque of 216–240 inch-pounds (24–27Nm). Loose connections will overheat.
