1. Use the positive and negative metal contacts and DC connectors supplied with the SUN2000.
Using other models of positive and negative metal contacts and DC connectors may result in
serious consequences. The caused device damage is not covered under any warranty or
service agreement.
2. The metal contacts supplied with the DC connectors are either cold forming contacts or
stamping forming contacts. Crimp the metal cold forming contacts using crimping tool
UTXTC0005 (Amphenol, recommended) or H4TC0001 (Amphenol). Crimp the metal stamping
forming contacts using crimping tool H4TC0003 (Amphenol, recommended) or H4TC0002
(Amphenol). Choose the crimping tools that fit the metal contacts.
3. Before connecting DC input power cables, label the cable polarities to ensure correct cable
connections. If the cables are connected incorrectly, the inverter may be damaged.
4. Pull back the DC input power cables to check whether the cables would be disconnected.
5. If DC input power cables are reversely connected and the DC switch is ON, do not turn off the
DC switch immediately. Otherwise, the equipment may be damaged. You can disconnect the
DC input power cable on the PV string side or wait until the PV string voltage reduces to a value
within the safety range. Then, turn off the DC switch, remove the positive and negative
connectors, and rectify the connection.
