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.

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 SUN2000L-(4.125KTL–4.95KTL)-JP must be cut off. If the DC connectors of

SUN2000L-(4.125KTL–4.95KTL)-JP are directly connected to SUN2000-4.95KTL-NHL2, the

SUN2000 may be burnt.

•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.
