M4-CG Series General Purpose Application Controller ...

1 M4-CG Series General Purpose ApplicationController Installation GuideApplicationThe CG Series General Purpose Application controllersare well-suited for controlling a wide variety of facilityand HVAC equipment, including fan coils, air handlingunits, packaged HVAC equipment, and central plantequipment. CG Series controllers run pre-engineered anduser-programmed Series controllers include an integral real-time clock,which enables the controllers to monitor and controlschedules, calendars, and trends, and operate forextended periods of time as standalone controllers whenoffline from the Metasys system ProtocolsCG Series controllers can communicate using multiplecommunication protocols depending on model andconfiguration.

2 CGE controllers communicate using theBACnet /IP communication protocol. CGM controllerscommunicate using the BACnet MS/TP, N2 or wirelessZigbee communications protocols, with the addition ofZFR183x Pro Wireless Field Bus controllers in BACnet/IP or BACnet MS/TPcommunication mode are BACnet network-compliantdevices. The BACnet protocol is a standard for ANSI,ASHRAE, and the International Standards Organization(ISO) for building running in N2 mode can be used to maintainor modernize sites with installed legacy Johnson Controls controllers. For installation and commissioning support,and tips for efficient and safe replacement, referto the Modernization Guide for Legacy N2 Controllers(LIT-12012005) and the Controller -specific information about mapping N2 Objects in controllerswith switchable communications protocols, refer to theN2 Compatibility Options chapter of the Controller Tool Help(LIT-12011147).

See BACnet/IP Ethernet Network Topology for CGE controllersMountingObserve the following guidelines when mounting acontroller: Ensure the mounting surface can support thecontroller, DIN rail, and any user-supplied enclosure. Mount the Controller horizontally on 35 mm DIN railwhenever possible. Mount the Controller in the proper mounting position.

8 Mount the Controller on a hard, even surface wheneverpossible in wall-mount applications. Use shims or washers to mount the Controller securelyand evenly on the mounting surface. Mount the Controller in an area free of corrosive vaporsand observe the Ambient Conditions requirements inTable Series General Purpose Application Controller Installation Guide2 Provide for sufficient space around the Controller forcable and wire connections for easy cover removaland good ventilation through the Controller (50 mm[2 in.] minimum on the top, bottom, and front of thecontroller). Do not mount the Controller on surfaces prone tovibration, such as ductwork. Do not mount the Controller in areas whereelectromagnetic emissions from other devices or wiringcan interfere with Controller panel or enclosure mount applications, observe thefollowing additional guidelines: Mount the Controller so that the enclosure walls donot obstruct cover removal or ventilation through thecontroller.

9 Mount the Controller so that the power transformerand other devices do not radiate excessive heat to thecontroller. Do not install the Controller in an airtight 3: Controller mounting positionMounting features and dimensionsFigure 4: Back of CGE09090 and CGM09090 controllerFigure 5: Back of CGE04060 and CGM04060 controllerNote: Mounting dimensions are listed in millimeters inthe above figures. The DIN rail channel and the mounting clips areshown in an extended rail mount applicationsAbout this task: To mount a Controller horizontally on a 35 mm DIN rail(recommended method), complete the following steps:1. Securely mount a 20 cm (8 in.) or longer sectionof 35 mm DIN rail horizontal and centered in thedesired space so that the Controller mounts in thehorizontal Pull the two bottom mounting clips outward fromthe Controller to the extended position (Figure 4 orFigure 5).

Hang the Controller on the DIN rail by the hooks atthe top of the (DIN rail) channel on the back of thecontroller (Figure 4 or Figure 5), and position thecontroller snugly against the DIN Push the bottom mounting clips inward (up) tosecure the Controller on the DIN rail. To removethe Controller from the DIN rail, pull the bottommounting clips out to the extended position andcarefully lift the Controller off the DIN mount applicationsAbout this task: To mount a Controller directly on a wall or other flatvertical surface, complete the following steps:1. Pull the two bottom mounting clips outward andensure they are locked in the extended position asshown in Figure 4 or Figure Determine the proper mounting position thecontroller will be installed.
