Installing AC Output Power Cables

2.2
Cable Type
A single cable
NOTE
1. UL1015 copper-core cables that can withstand 105 °C (221 °F) are recommended.
2. The table lists only the recommended cable specifications. For more information about cable
specifications, see the SUN2000-(25KTL, 30KTL)-US User Manual.
3. It is recommended that the AC output cable be routed through a pipe for protection. The maximum
pipe outer diameter allowed is 40.5 mm (1.59 in.).
1. Prepare an AC output power cable. Use hydraulic pliers to crimp the conductor part of the OT
terminal and cover the crimping area with heat shrink tubing or PVC insulation tape.
2. Remove the AC OUTPUT waterproof cable connector.
3. Route the prepared AC output power cable through the cable routing pipe.
4. Route the AC output cable and the cable routing pipe through the AC OUTPUT hole.
5. Connect the wires of the AC output cable for the SUN2000 to L1, L2, L3, and N on the AC terminal
block.
