警告：
•如果使用寿命单个变压器给μC²SE和其附件供电，为了避免损坏设备，把不同控制器或主控制板上的所有
G0端口连接到变压器的次线圈的同一端口上；所有G端口连接到变压器次圈的另一个端口上。
•对于居住环境中使用，需要使用屏蔽电缆用于tLAN连接（N55014-1）。
•避免V+和GND间短路，不要损坏设备。
•把电力电缆与传感器，开关量输入和串行电缆分开。
•使用单独的变压器给电子控制器供电。
抗电击保护和维护注意
在装配，维护和更换设备前需要断开电源。
系统由控制板（MCH200*03*）和其它的选件卡（MCH200002*，MCH200485*，MCHRTF****，CONVO-
NOFF*，CONV0/10a*，EVD000040*），这些设备是整合到I类或I I类设备内。抗电击等级由制造商根据系统
的控制设备整合。为了避免因错误的接线引起短路；制造商必须确保设备内控制内置含有该方面的保护。

Introduction
The μC2 is an electronic controller for the complete management of chillers, heat pumps, condensing units and air/
air units with one circuit and 2 hermetic compressors. The expansion board (code MCH200002*) allows the mana-
gement of up to 2 circuits and 4 hermetic compressors.
Characteristics of the connectors
The connectors can be purchased separa-
tely from CAREL (MCH2CON0**) or from
the manufacturer, Molex:
Contact code and cross-section of the connection cables
to the 12- and 14-pin connectors (for crimping, use the
special Molex tool‚ 69008-0724):
Molex connector code number of pins Molex contact code Cross-section of the cables

Parameter programming key option
With the controller OFF, insert the key PSOPZKEY00 in the connector KEY/SPV. Connect and disconnect the serial
and programming key options with the 12-pin connector (relay) removed.
Note: the conguration jumper must be inserted in position A (technical leaet MCH200485*)
Supervisor option
Connect the serial option (code MCH200485*) to the connector KEY/SPV.
Warnings
• If using a single power transformer for the μC2SE and the accessories, connect all the G0 terminals on the various
controllers or boards to the same terminal on the secondary, and all the G terminals to the other terminal on the se-
condary, to avoid damaging the instrument;
• For use in residential environments, a shielded cable (conductor + shield) is required for the tLAN connections (EN
55014-1);
• Avoid short-circuits between V+ and GND so as to not damage the instrument:
• Separate the power cables (relay outputs) from the probe, digital input and serial cables;
• Use the power transformer exclusively dedicated to the electronic controllers.
Protection against electric shock and warnings for maintenance
Disconnect the power supply before working on the board during the assembly, maintenance and replacement ope-
rations.
The system made up of the control board (MCH200*03*) and the other optional cards (MCH200002*, MCH200485*,
MCHRTF****, CONVONOFF*, CONV0/10A*, EVD000040*) represents a control device to be incorporated in class I
or class II equipment. The class of protection against electric shock depends on how the control device is integra-
ted into the unit made by the manufacturer.
The protection against short-circuits, due to defective wiring, must be guaranteed by the manufacturer of the equip-
ment that the control device is built into.
