Chapter 5 Main Circuit Terminals MS300 5-2 Main Circuit Terminal Specifications Use the specified ring lug for main circuit terminal wiring. See Figure 5-6 and Figure 5-7 for ring lug specifications. For other types of wiring, use the wires that comply with the local regulations. After crimping the wire to the ring lug (must be UL and CSA approved R/C (YDPU2)), install heat shrink tubing rated at a minimum of 600 V AC insulation over the live part. Refer to Figure 5-7. Main circuit terminals: R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, , DC-, DC+/+1, +2/B1, B2 Note: There is no T/L3 terminal for one-phase models.
