
If the SmartLogger uses an AC power cable for communication, an MCB or a knife fuse
switch needs to be installed to prevent device damage in the case of short circuits.

If the SmartLogger communicates with a inverter over an AC power cable, both the cable
from the knife switch to the MCB and the cable from the busbar to the knife switch need
to be prepared by the customer. You are advised to use a three-core multi-wire outdoor
armor cable with a cross-sectional area of 10 mm
voltage on the low-voltage side of the box-type transformer is less than or equal to 500 V,
the operating voltage to the ground of the AC power cable 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 to the ground
of the AC power cable should be greater than or equal to 1000 V.

The SmartLogger can connect to the inverter over 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.

The power cable delivered with the SmartLogger is 1 m long, the power adapter cable is
1.5 m long, the network cable is 2.2 m long, and the AC power cable is 1.5 m long.
Reserve the installation positions for components based on the cable lengths.
