This section describes how to connect the SmartLogger to a inverter and other devices in the
scenario without a smart array controller.

In a scenario with a smart array controller, the SmartLogger is installed before delivery. Devices can
connect to the SmartLogger over RS485 communications cables or AC power cables. For detailed
operations, see the user manual for the appropriate smart array controller.
 The SmartLogger provides six COM ports to connect to RS485 communications cables. Connect
Huawei equipment and third-party equipment to different COM ports if both of them need to
connect to the SmartLogger. If only Huawei equipment or third-party equipment needs to connect to
the SmartLogger, connect the equipment to an idle COM port.
 If the SmartLogger2000-10/10-B/11-B connects to equipment over an RS485 communications cable,
an RS485 signal SPD is recommended. For details about installing and wiring the RS485 signal SPD,
see A Installing and Wiring the RS485 Signal
 If the SmartLogger2000-10-C/11-C connects to equipment over an RS485 communications cable, no
RS485 signal SPD is required. This document uses the SmartLogger2000-10-C as an example to
describe the cable connections.
Ensure that all cables are connected securely.
The SmartLogger has no start key. Before the electrical connections for the SmartLogger
are complete, do not connect a power adapter to it.
