Remove the cover and hang it on the hook of the enclosure door. 4.5 Installing the AC Output Power Cable NOTICE To avoid damaging the rubber liner, do not route a cable with a crimped OT terminal directly through it. Do not adjust the cable when the locking cap is tightened. Otherwise, the rubber liner will shift, which affects the IP rating of the device. Ensure that AC terminations provide firm and solid electrical connections. Otherwise, the device may fail to operate or experience any fault that will damage the terminal block. If the AC output power cables are subject to a pulling force because the inverter is not installed stably, ensure that the last cable that bears the stress is the PE cable. Ensure that the AC output power cable and cable connector are in good contact. Cable connector AC output power cable 7
4.6 Installing the DC Input Power Cable Requirements for selecting DC input terminals 1. Evenly distribute DC input power cables on the DC input terminals controlled by the two DC switches. 2. Maximize the number of connected MPPT circuits. CAUTION Ensure that the PV module output is well-insulated to ground. Before inserting the positive and negative connectors respectively into the positive and negative DC input terminals of the SUN2000, ensure that the DC voltage does not exceed 1500 V DC using a multimeter set to the DC position and check that the cable polarities are correct. Otherwise, the SUN2000 will be damaged. 8
