System 450™ Series Modular Control Systems with Standard Control Modules Technical Bulletin

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.
2. Install appropriate screws or fasteners, leaving the screw heads approximately one to two turns away from
flush to the mounting surface.
3. Position the assembly mounting slots over the screw heads, and then carefully tighten the mounting screws to
secure the assembly to the surface.
Note: If you mount the modules on an uneven surface, use shims or washers to mount module assembly
evenly on the surface.
Refer to the sensor installation instructions referenced in System 450 Overview
on page 3 for information on
locating and mounting System 450 compatible sensors.
Wiring System 450 Components
When wiring your System 450 control system, observe the following guidelines. See Figure 18, Figure 19, and
Figure 20 for wiring terminal locations and designations. See Related Documentation
on page 61 for the electrical
ratings for System 450 modules used to built System 450 standard control systems.
Risk of Electric Shock.
Disconnect or isolate all power supplies before making electrical connections. More than one disconnection or
isolation may be required to completely de-energize equipment. Contact with components carrying hazardous
voltage can cause electric shock and may result in severe personal injury or death.
Risque de décharge électrique.
Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires pourcouper entièrement l'alimentation de l'équipement. Tout contact
avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de
provoquer des blessures graves, voire mortelles.
IMPORTANT: Use copper conductors only. Make all wiring in accordance with local, national, and regional
regulations.
IMPORTANT: Do not exceed the System 450 module electrical ratings. Exceeding module electrical ratings
can result in permanent damage to the modules and void any warranty.
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.
