2 — INSTALLATION & WIRING: High Current Connections
HIGH CURRENT CONNECTIONS
There are two options for supplying power to the 1310 controller: using pins
23 and 24 on the J1 connector, or using the B- and B+ connection tabs.
Since the controller has many outputs, it is possible for it to draw a
considerable load from the battery. If more than 3 amps current is expected in
the total system, the B- connection tab must be used as the controller ground
reference. Likewise, if the system could draw more than 3 amps from B+, the
B+ connection tab must be used to power the controller.
If the driven loads are inductive, the load’s power must be connected to
the B+ connection tab, and the the B+ connection tab must be connected to
the battery; see wiring shown in Fig. 3, page 11.
When using the high current connection tabs, be careful not to bend or
break the tab while tightening the bolt. For best results, use a pressure washer
(convex side up) under the bolt head. This will help prevent the joint from
loosening over time.
To avoid overheating the joint, make sure the wire cable gage is sufficient to
carry the continuous and maximum loads that will be seen by the controller.
