NOTE
1. Select copper wires with rated voltage of 600 V and
temperature resistance of 75°C or 90°C for wiring.
2. For UL installation compliance, use copper wires when
installing. The wire gauge is based on a temperature
resistance of 75 °C, in accordance with UL requirements
and recommendations. Do not reduce the wire gauge when
using high-temperature resistant wires.
3. Use specified ring lug for terminal wiring. See Figure 1 and
Figure 2 for ring lug specifications. For other types of
wiring, use the wires that comply with local regulations.
4. After crimping the wire to the ring lug (must be UL and CSA
approved R/C (YDPU2)), then install heat shrink tubing
rated at a minimum of 600 V
