• 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 and that the cable polarities are correct. Otherwise, the SUN2000 will be
damaged.
1. Crimp the metal contacts using crimping tool UTXTC0003 (Amphenol, recommended) or
UTXTC0002 (Amphenol).
2. Use the positive and negative Amphenol UTX metal contacts and DC connectors supplied with
the SUN2000. Using other positive and negative metal contacts and DC connectors may result
in serious consequences. The caused device damage is not covered under any warranty.
3. Before connecting the DC input power cable, label the cable polarities to ensure correct cable
connections. Otherwise, the SUN2000 may be damaged.
4. Measure the voltage at the DC input end using a multimeter. If the voltage is a negative value,
the DC input polarity is incorrect. Correct the polarity. If the voltage is greater than 1500 V, too
many PV modules are configured to the same string. Remove some PV modules.
5. If the DC input power cable is reversely connected and the DC switch is turned on, do not
perform operations on the DC switch or the positive/negative connectors immediately.
Otherwise, the device may be damaged. The caused device damage is not covered under any
warranty. Wait until the night when solar irradiance declines and the PV string current drops
to below 0.5 A. Then turn the two DC switches to the OFF position, remove the positive and
negative DC input power connectors, and correct the polarity of the DC input power cable.
