Installation Method
Steps:
1. To install the meter on the rail insert the top of the rail into the groove on the
back of the meter. Pull the metal clips back and slide the rail across the groove of
the meter.

2. Use the metal clips to tighten the rail to complete installation.
3. Before mentioning this step, the steps needed to remove the seal/cover need to
To attach seal/cover back onto the meter place the left side of the cover down onto
meter and press down on the right side. When installed correctly you will hear a
clicking sound. The steps to attach the other cover is opposite to the above step.
4. After inserting the cover, tighten the sealing screws and lay the seal.

In settings mode, scroll to the page S-01 to set the communication address, the
address can be any integer between 1 and 247. Setting method is as follows: Press
shift the cursor by “SET” key, when the cursor is moved to the rightmost location,
The other settings are the same as the operation of address.
The communication baud rate can be set to 1200, 2400, 4800, 9600, 19200 or
38400.
The communication parity can be set to EVEN, ODD, NONE1 or NONE2.
Communication
KW350 meter communication uses RS485 interface and Modbus -RTU
protocol. Wiring terminals are A, B, S. If master device does not support RS485 but
only RS232, an adapter named RS232/RS485 needs to be used for connection. In
practical alapplications, there are multiple topologies for RS485 network, such as
Line, Star and Wye. In addition, the Display Module has an infrared port to support

Energy Pulse Output
Users can choose either energy pulse output or reactive energy pulse output. The
energy pulse output function needs an external auxiliary power to supply.
Relay Output(RO)
Two modes available: control or alarm output. One module only supports one
mode at a time.
Event Logging
The KW350 series also provides a system status self-testing feature. When
crucial operations are implemented (such as programming, open/close the cover,
clear the demand, clear the meter's data etc), it immediately logs the event time
and the event type.
