Requirements on Cable Specifications
Cables with high rigidity, such as armored cables, are not recommended, because poor contact
may be caused by the bending of cables.

Procedure
Step 1 Remove the insulation layer of the DC input power cable by an appropriate length using a
wire stripper.
Step 2 Crimp positive and negative metal contacts.
Step 3 Insert the contacts into the corresponding positive and negative connectors.
Step 4 Tighten the lock nuts on the positive and negative connectors.
Step 5 Use a multimeter to measure the voltage between the positive and negative terminals of the
PV string (measurement range no less than 1500 V).

Step 6 Insert the positive and negative connectors into the corresponding DC positive and negative
input terminals of the SUN2000.

Use the Amphenol UTX PV connectors supplied with the SUN2000. If the PV connectors
are lost or damaged, purchase the connectors of the same model. The device damage
caused by incompatible PV connectors is not covered under any warranty.
Crimp the metal contacts using crimping tool UTXTC0003 (Amphenol, recommended) or
UTXTC0002 (Amphenol).
If the voltage is a negative value, the DC input polarity is incorrect and needs correction.
If the voltage is greater than 1500 V, too many PV modules configured to the same string.
Remove some PV modules.
