stamping forming contacts. Crimp the metal cold forming contacts using crimping tool
H4TC0001 (Amphenol). Crimp the metal cold stamping contacts using crimping tool
H4TC0002 (Amphenol). Choose the crimping tools that fit the metal contact types. Do not
mix up the tools.
3. The SUN2000L DC input voltage must always be lower than or equal to 600 V DC.
4. Before installing the DC input power cable, label the cable polarities correctly to ensure
correct cable connections.
5. Use the positive and negative connectors supplied with the SUN2000L.
6. If polarity of the DC input power cable is reversed and the DC switch is ON, do not turn off
the DC switch immediately or unplug positive and negative connectors. The device may be
damaged if you do not follow the instruction. This damage is not covered under any
warranty or service agreement. Wait until the solar irradiance declines at night and the PV
string current reduces to below 0.5 A, and then turn off the DC switch and remove the
positive and negative connectors. Correct the string polarity before reconnecting the string
to the SUN2000L.
