Transport and Storage
Before you transport and storage the Repeater, read and observe the clause 4 titled “Transport and
storage” in this document.
Installation
Power must be cut off before install or remove CT103Repeater.
Before you install or remove the Repeater, find and read the “Product Installation Guide” first.
Operation
1. Do not break the seal without authorized operator.
2. Never remove the Repeater cover while the Repeater is in operation. Doing so will expose circuits
and components and can lead to injuries, fire or damage to the Repeater.
3. Repeater working voltage must less than 120% nominal voltage (120%Un). Long time over voltage
can lead to fire or damage to the Repeater.
4. Before you install or change external battery, read and observe the section 2.2 titled “external battery”
in this document first. Incorrect operation may cause electrical shock!!
6. Do not operate the Repeater with wet hands.

1 Product introduction
CT103 is a repeater with RF Uplink & RS485 downlink. It’s a bridge between the Concentrator and
Meter to transfer the meter’s data. The Repeater comes with an RF module that connects the Repeater
via the RS485 interface. The communication Repeater can provide a path for forwarding weak signals,
so that the Concentrator can reliably communicate with the Repeater. The communication is not
encrypted. The Repeater only implements transmit through function.
As a part of Kaifa repeater solution, the CT103 provides RS485 port and SPD detection port and
integrated Repeating functions as described in section 1.3.

2 Repeater Installation
2.1 Installation guide
CT103Repeater should be installed at a dry Meter Box. Installation environment temperature must
not exceed Repeater operation temperature range (+10℃~ +85℃); Working voltage must in the range of
184Vac~276Vac, 60±5%Hz.
Please see Meter Box installation guide for details.
2.2
External battery
External changeable battery can provide backup energy for Repeater’s RTC. The recommended battery
size is LS14250E. Only authorize utility member can remove the battery, it is not allowable to remove
battery for consumer. Please see the detailed dimension as following:
1) Power off the Repeater, open the meter box, pull off the plug, and replace the battery, close the
Meter Box.
3 Event record
3.1 Repeater’s event record
When the event occurred, Repeater only transfers to Concentrator through RF module, it contains:
event_code1 Power off: If power off, when power up again, Repeater can detect the last power off
event, and report the last gasp event with date and time to concentrator.
event_code2 SPD OK: SPD give a disconnect signal to Repeater (only detection in power up
situation). After five seconds, the RF LED will alternating flicker and Repeater will report the
SPD OK event with date and time stamp to concentrator.
event_code3 SPD FAIL: SPD give a connect signal to Repeater (only detection in power up
situation). After five seconds, the RF LED will alternating flicker and Repeater will report the
SPD FAIL event with date and time stamp to concentrator.
event_code4 Meter Box open: When Meter Box is opened, the RF LED will alternating flicker. After
five seconds, Repeater will report the Meter Box close event with date and time stamp to
concentrator.
event_code5 Meter Box close: If the Meter Box has been opened, When the Meter Box is closed,
the RF LED will alternating flicker. After five seconds, Repeater will report the Meter Box open
event with date and time stamp to concentrator.
