1. The information in this document is subject to change without notice. Every effort has been
made in the preparation of this document to ensure accuracy of the contents, but all
statements, information, and recommendations in this document do not constitute a
warranty of any kind, express or implied.
2. Before replacing the device, carefully read the SUN2000-4.95KTL-NHL2 User Manual to get
familiar with product information and precautions.
3. Before replacing the device, check whether the configurations of SUN2000L-(4.125KTL–
4.95KTL)-JP and SUN2000-4.95KTL-JPL0 can be viewed. If they can be viewed, record the
parameter settings for setting or checking parameters after the replacement.
4. Before replacing the device, check whether the cables are long enough. If not, prepare
appropriate cables.
1SUN2000L-(4.125KTL–4.95KTL)-JP Replacement Scenarios
•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.
1. Power off the SUN2000 to be replaced.
2. Remove the AC connector and remove the AC output power cable
from the mating socket for future use.

•Ensure that the PV module output is well insulated to ground.
•Use the positive and negative Staubli MC4 metal terminals and DC connectors supplied with
the SUN2000. Using incompatible positive and negative metal terminals and DC connectors
may result in serious consequences. The caused device damage is not covered under warranty.
•The DC input voltage of the SUN2000 cannot exceed the maximum input voltage under any
condition.
•Before installing DC input power cables, label the cable polarities to ensure correct cable
connections.
•If the polarities of the DC input power cables are reversed, do not operate the DC switch or
the positive/negative connector immediately. Failing to do so may cause device damage,
which is not covered under warranty. Wait until the night when solar irradiance declines and
the PV string current drops to below 0.5 A. Then set the DC switch to OFF, remove the
positive and negative connectors, and correct the polarities of the DC input power cables.
