On the ACR Network power meters faceplate,
Input voltage should not higher than 120% of
product's Input voltage(100V or400V), otherwise,
should use PT;
1A fuse should be mounted on the voltage Input
end;

4.4.2电流输入
Standard rated Input current is 5A or1A, if
greater than 5A,the external CT should be used;
When wiring, ensure that the Input current and
voltage has same
terminal is connected with A phase voltage, then 5,
6# terminal must be connected with A phase
current, otherwise, Display value and symbol error
may occur; while ensure the connection

接线时确保输入电流与电压相序一致，即1号接
线端接A相电压则5、6号接线端一定要接A相电流，否
则会出现显示数值和符号错误；同时确保电流进出线
连接正确（打*号端子接进线）；
如果使用的CT上连有其它仪表，接线应采用串
接方式；
EPI--吸收有功电能
EPE--释放有功电能
EPI-- capture active Electric energy
EPE-- release active Electric energy
EQL--感性无功电能
correctness of current inlet and outlet(symbol *

EQC--容性无功电能。
EQL-- Inductive reactive Electric energy
EQC-- capacitive reactive Electric energy.
Right side k，M: k=kilo; M= million
右侧k、M代表所显示项目的单位数量级为千或

If the used CT connected with other meters，the
connection is adopting series connection mode;
When wiring, using Connector bar is
recommended, not connected with CT directly, to
facilitate dismounting;
Before removing product current Input
connection, firstly, cutoff CT primary circuit or short
the secondary circuit!
安装接线时建议使用接线排，不要直接接CT，
以便于拆装；
Example: As below figure shows: EPQ indicator
lights, the first row digitron Display EPI, currently
Display the capture active Electric energy, k
indicator lights, shows Electric energy Unit is kWh,
the Electric energy reading value is the second row
digitron plus the third row digitron, the Electric
energy shown in below figure is 123456.78kWh.
例：如下图所示，"EPQ" 指示灯亮，排数码管显示
EPI，表示当前显示吸收有功电能，k指示灯亮，表示
电能单位为kWh，读电能时将第二排数码管和第三排
数码管连读，如下图所示电能为123456.78kWh.
去除产品电流输入连线前，先切断CT一次
回路或者短接二次回路！
