2.当 Iunbl 为 OFF 档时为电流不平衡保护、断相保护功能关闭。
3. NDM3E-125/250 短路瞬时 Ii 内置 15In。NDM3E-400/630/800 短路瞬时 Ii 内置 13In。
4. 电动机保护断路器仅有 NDM3E-630/800。
Notes: 1. When Isd is OFF, it will turn off for short delay protection.
2. When Iunbl for the OFF，The current unbalance protection, lack phase protection is off.
3. Short-circuit instantaneous Ii to 15In of NDM3E-125/250. Short-circuit instantaneous Ii to 13In of
NDM3E-400/630/800
4. Motor protection circuit breaker only for NDM3E-630/800
3.2.4 控制器的整定电流、整定时间调节(通讯型)
通讯型控制器的电流、时间调节需要通过通讯用上位机电脑来调节，需要客户配置的相关设备如下：
Setting current and time adjustment of controller (communication)
The adjustment of setting current and time of communication controller can be completed with
the upper computer used for communication, relevant equipments needed are as follows:
（1）电脑一台（台式机或笔记本，电脑需要有 RS-232 接口）；
One computer (Desktop or laptop with RS-232 interface);
（2）DC24V 电源（给附件通讯模块提供电源，详细要求请见第 3.2.2.4.1 条。）；
DC24V power supply (Provide power for communication module, see Section 3.2.2.4.1for
detailed requirements);
（3）RS-232 转 RS-485 转换模块；Conversion module of RS-232 to RS-485;
（4）RS-485 通讯用通讯屏蔽线（也可以用双绞线替代，正常产品连接时只能用通讯屏蔽线）。
RS-485 communication shielded cable (It can be replaced by twisted pair, but only
communication shielded cable can be used for normal product connection)
3.2.4.1 通讯联接接线 Communication connection wiring
通讯模块与电操机构的连接图请见第 3.2.2.4.2 条。
For connection figure of communication module and motor-operated mechanism see Section
通讯型断路器与电脑连接方式如下：
Connection of communication breaker and the computer are shown as follows:
将产品的通讯模块的电源和通讯线接好，通讯模块的通讯线接到“RS-232 转 RS-485 转换模块”的
RS-485 端（注意极性不可接错），再将“RS-232 转 RS-485 转换模块”配套提供的“串口线”将“RS-232
转 RS-485 转换模块”的 RS-232 端和电脑的“RS-232 接口”连接好，如“RS-232 转 RS-485 转换模块”有
电源请将电源线接好，请见图 5，最后接通电源。
Connect the communication module’s power supply and communication wires, with the latter one
connecting to RS-485 terminal of “RS-232 to RS-485 module” (poles can’t be wrongly connected),
and then using the serial port line provided accompanying with “RS-232 to RS-485 module” to
connect RS-232 terminal of “RS-232 to RS-485 module” and “RS-232 interface” of the computer. If
the “RS-232 to RS-485 module” is provided with a power supply, please connect the power line (see
Fig. 5), and plug in the power supply at last.
