Wiring configurations for Remote Control Green Terminal
2.2.3 Chassis Ground
Use 16 AWG (1.5 mm²) or a thicker cable to connect the vehicle earth or chassis ground. Perform this
connection prior to any other connection.
2.2.4 DC Input Connection
Prior to installation:
• The cable and fuse sizes in Table 2.2.4.1 are recommended for connection between supply battery
and inverter. The DC supply cables should be as short as possible and no longer than the values
shown in Table 2.2.4.1.
• The size of the cable should be thick enough to maintain a voltage drop of less than 2% when
carrying the maximum input current. This will help prevent frequent low-input voltage warnings and
shutdown.
