Non-Smart Array Controller Scenario
NOTICE
1. If the SmartLogger communicates with a SUN2000 over an AC power cable, an MCB and a knife
switch need to be installed to prevent device damage in the case of short circuits.
2. If the SmartLogger communicates with the SUN2000 over an AC power cable, prepare the cable
from the knife fuse switch to the MCB and the cable from the busbar to the knife fuse switch by
yourself. Recommended: a three-core outdoor armor cable with a cross-sectional area of 10 mm
for each core wire. When the rated AC voltage on the low-voltage side of the box-type transformer
is less than or equal to 500 V, the operating voltage between the AC power cable and the ground
should be greater than or equal to 600 V. When the rated AC voltage on the low-voltage side of
the box-type transformer is greater than 500 V and less than or equal to 800 V, the operating
voltage between the AC power cable and the ground should be greater than or equal to 1000 V.
3. The SmartLogger can connect to the SUN2000 through an RS485 communications cable or AC
power cable. If RS485 is used, there is no need to connect an AC power cable between the
SmartLogger and the MCB in the scenario without a smart array controller.
4. The power cable delivered with the SmartLogger is 1 meter long, the power adapter cable is 1.5
meters long, the network cable is 2.2 meters long, and the AC power cable is 1.5 meters long.
Reserve the installation positions for components based on the cable lengths.
