1. Usethe positive and negative metalcontacts and DCconnectors supplied with the SUN2000.
Using other models of positive and negative metalcontacts and DC connectors mayresult in
serious consequences. The caused device damage isnot covered under any warranty or service
agreement.
2. The metal contacts supplied with the DC connectors are either cold forming contacts orstamping
forming contacts. Crimpthe metalcold forming contacts using crimping tool H4TC0001
(Amphenol). Crimp the metal stamping forming contacts using crimping tool H4TC0002
(Amphenol). Choose the crimping tools that fitthe metalcontact types. Do not mixup the tools.
3. Before connecting DC input power cables, mark the polarities on the cables to ensure that
the cables are connected correctly. If the cables are connected incorrectly, the device may
be damaged.
4. Insert the crimped metal terminals of the positive and negative power cables into the
appropriate positive and negative connectors. Then pull the DC input power cables to ensure
that they are connected securely.
5. Connect the positive and negative connectors to the appropriate positive and negative DC
input terminals. Then pull the DC input power cables to ensure that they are connected
securely.
6. If the DC input power cables are reversely connected and the DC SWITCH is ON, do not turn
off the DC SWITCH immediately. Otherwise, the inverter may be damaged and the damage
is beyond the warranty scope. Wait until the PV string voltage reduces to the safety range
(below 60 V DC). Then, turn off the DC SWITCH, remove the positive and negative
connectors, and rectify the connection.

5Setting Monitoring Parameters
1. If no data collector is used, set the following parameters before connecting the SUN2000 to the
power grid. For the other parameter settings, see the SUN2000 (8KTL-28KTL) User Manual. If a
data collector is used, see the SmartLogger1000 User Manual for the parameter settings.
2. The preset password for Common User, Advanced User, and Special User is 000001. Use the
preset password to log in to the SUN2000 for the first time and then change the password to a
new one to ensure the account security.
4System Power-on
1. Switch on the AC circuit breaker between the SUN2000 and the power grid.
2. Ensure that the DC Switch at the bottom of the SUN2000 is ON.
3. (Optional) Measure the temperatures at the joints between the DC terminals and the connectors.
