1. Safety notice

The 103EM series smart energy meter does not require special mechanical or

electrical tools for the installation. Mounting position (with any angle of tilt) has no

effect on the measurement functions of the meter.

Please note that meter wiring must be made according to applicable wiring diagram.

Incorrect connection of the meter to the electricity network could cause major display

problem and serious damage to the meter. Before starting the meter operation, it must

be ensured that the local conditions of the energy system are consistent with the data

shown on the nameplate of the meter. For the communication cables, it is preferred to

use shielded ones. Make sure that the cables are not damaged and free of

non-mechanical stress when installing. Also make sure that the meter is not energized

during meter installation.

Repairs or removing the meter cover can be made only by a qualified electrician who is

familiar with the associated risks. Capacitors in the meter may still be charged even if

the meter is disconnected from all energy sources

5. Wiring diagrams

Note: the following wiring diagram shows the energy meter with pulse output and

the RS-485 interface. For other outputs, please contact [e-mail] for

details.

Please note that the relay output is a miniature switch. It cannot be connected to

power line directly. You must use an external smart switch and an external relay

to provide remote connect/disconnect function.
