Installation Instructions
C450CEN-1
Application
IMPORTANT: Use this System 450™ Series Control Module with Ethernet Communications only as an
operating control. Where failure or malfunction of the System 450™ Series Control Module could lead to
personal injury or property damage to the controlled equipment or other property, additional precautions must be
designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems
or safety or limit controls, intended to warn of or protect against failure or malfunction of the System 450™
Series Control Module.
IMPORTANT: Utiliser ce System 450™ Series Control Module with Ethernet Communications uniquement en
tant que dispositif de régulation. Lorsqu'une défaillance ou un dysfonctionnement du System 450™ Series
Control Module risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre
équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires.
Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou
d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du System 450™ Series Control Module.
The System 450™ Series is a family of modular, digital electronic controls that is easily assembled and set up to
provide reliable temperature, pressure, and humidity control for a wide variety of HVACR and commercial and
industrial process applications.
The System 450 control modules allow you to configure custom application-specific control systems with up to
three input sensors and ten (relay or analog) outputs, including control systems that can monitor and control
temperature, pressure, and humidity applications simultaneously.
C450CEN-x control modules feature an LCD and four-button touchpad UI that allows you to set up a System 450
control system, and an RJ45 Ethernet network port that enables you to connect your control system to and
communicate across an Ethernet network.
The System 450 control module with Ethernet communications has an integral web server that supports browser
access. The web server can be configured to deliver System 450 web pages to client browsers and allows you to
monitor your control system status and change your control system configuration in simple, user-friendly web
pages.
Refer to the System 450™ Series Modular Control Systems with Communications Control Modules Technical
Bulletin (LIT-12011826) for detailed information on designing, installing, setting up, and troubleshooting System
450 Series control systems with network communications. The technical bulletin can be accessed and downloaded
on the Johnson Controls® QuickLIT website.
System 450 control modules with network communications also include the High Input-Signal Selection,
Differential Control, Output Signal Update Rate, and Output Signal Dead Band features.

Conduit Hole (Nominal Trade Size) (2-1/2) Location Considerations Observe the following System 450 location guidelines: • Ensure that the mounting surface can support the module assembly, mounting hardware, and any (user- supplied) panel or enclosure.
  • Page 3 Note: If your System 450 control system uses a power module, the power module must be plugged into the right side of the control module. To direct-mount modules to walls and other flat surfaces using the four keyhole slots: 1. Plug the modules together, remove the module covers, place the module assembly horizontally against the wall surface in a suitable location, and mark the mount hole locations on the mounting surface (Figure 1).
  • Page 4 IMPORTANT: Run all low-voltage wiring and cables separate from all high-voltage wiring. Shielded cable is strongly recommended for input (sensor) and analog output cables that are exposed to high electromagnetic or radio frequency noise. IMPORTANT: Electrostatic discharge can damage System 450 modules. Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid damaging System 450 modules.
