Removing SUN2000-(2KTL-5KTL)-L0 or SUN2000L-(3KTL-5KTL)-CN
2.1
• Before removing the original SUN2000, ensure that the DC switch on the SUN2000 and all
the switches connected to the SUN2000 are set to OFF. Otherwise, the high voltage of the
SUN2000 may result in electric shocks.
• After the SUN2000 is powered off, the remaining electricity and heat may still cause electric
shocks and body burns. Therefore, put on protective gloves and dielectric boots and begin
operating the SUN2000 with specialized insulation tools five minutes after the power-off.

for Future Use
1. Power off the SUN2000 to be replaced.
2. Remove the AC connector for future use.
DC input terminals
3. Remove the DC connectors and use a cable cutter to cut off the terminals of
DC input power cables. Set the cables aside for future use.
• The DC terminals of SUN2000-(2KTL–5KTL)-
L0 or SUN2000L-(3KTL-5KTL)-CN must be
cut off. If the DC connectors of SUN2000-
(2KTL–5KTL)-L0 or SUN2000L-(3KTL-5KTL)-
CN are directly connected to SUN2000-
(2KTL–6KTL)-L1, the SUN2000 may be burnt.
• If the SUN2000 is connected to a smart PV
safety box, cut off the DC terminal
connected to the PV port on the SUN2000
and do not cut other DC terminals. Put the
cables aside for future use.
