2Installation Requirements

3Device Installation

Dimensions Space

Wall-Mounted Installation

•Install the SmartLogger and SmartModule on a flat and secure interior wall.

•When wall-mounting the SmartLogger and SmartModule, ensure that the cable connection area

faces downward for ease of cable connection and maintenance.

•You are advised to use the delivered tapping screws and expansion tubes.

1. Connect the SmartLogger to the SmartModule using a connecting plate.

If the SmartLogger

and SmartModule

have been

combined before

delivery, skip this

step.

2. Install the SmartLogger and SmartModule.

Guide Rail-Mounted Installation (Stand-alone)

•Before installation, prepare a standard 35 mm guide rail and secure it.

•The recommended effective length of the guide rail is 360 mm or greater.

•Ensure that the SIM card slot on the SmartLogger is not blocked.

Guide Rail-Mounted Installation (Combined)

•Before installation, prepare a standard 35 mm guide rail and secure it.

•The recommended effective length of the guide rail is 360 mm or greater.

•Ensure that the SIM card slot on the SmartLogger is not blocked.

1. Connect the SmartLogger to the SmartModule using a connecting plate.

2. Install the SmartLogger and SmartModule.

If the SmartLogger and

SmartModule have been

combined before delivery,

you only need to remove

the mounting ears and

guide rail clamps in the

middle. You do not need

to use a connecting plate

to connect the

SmartLogger and

SmartModule.

•Connect cables in accordance with the installation laws and regulations of the country or region

where the project is located.

•Before connecting cables to ports, leave enough slack to reduce the tension on the cables and

prevent poor cable connections.

Connecting the PE Cable

4.2

•To enhance the

corrosion resistance of

the ground terminal,

you are advised to

apply silica gel or paint

on it after connecting

the ground cable.

•If the SmartLogger is

connected to the

SmartModule over a

connecting plate,

connect a PE cable to

the ground point of the

SmartLogger or

SmartModule based on

site requirements.

Connecting the Ethernet Cable

4.3

•The SmartModule can be connected to the SmartLogger and a PC over the GE port.

•Connect the LAN port on the SmartLogger to one GE port on the SmartModule using an

Ethernet cable.

•If the delivered network cable is too short, you are advised to prepare a network cable of Cat 5e

or higher specifications and shielded RJ45 connectors. It is recommended that the cable length

be less than or equal to 100 m. When crimping the network cable, ensure that the shielding

layer of the cable is securely connected to the metal shell of the RJ45 connectors.

•It is recommended that the RS485 communication distance be less than or equal to 1000 m.

•The SmartModule can connect to RS485 communications devices, such as a solar inverter, an

environmental monitoring instrument (EMI), and a power meter over the COM port.

•Ensure that the RS485+ and RS485–terminals are respectively connected to the COM+ and

COM–ports on the SmartModule.

Cascading Connection

•You are advised to connect fewer than 30 devices to each RS485 route.

•The baud rate, communications protocol, and parity mode of all devices on the RS485

cascading link must be the same as those of the COM ports on the SmartModule.

Connecting the DI Signal Cable

4.6

•The SmartModule can receive DI signals such as remote power grid scheduling commands and

alarms over DI ports. It can only receive passive dry contact signals.

•It is recommended that the signal transmission distance be less than or equal to 10 m.
