The power wiring terminals are pressure terminations, UL and CSA rated at 90°C. See Table 3-5 for external
power cable terminations.
Figure 4-6 and Figure 4-8 show the location of the IBC–SW power cable terminals.
External DC input overcurrent protection and disconnect switch for the remote battery location (three or four
