Application refers to the design of the complete standby power system that usually includes:
• power distribution equipment
• transfer switches
• ventilation equipment
• mounting pads
• cooling systems
• exhaust systems
• fuel systems
Each component must be correctly designed so the complete system functions as intended. Application
and design is an engineering function generally done by specifying engineers or other trained specialists.
Engineers are responsible for the design of the complete standby system and for selecting the materials
and products required.
Installation refers to the actual set-up and assembly of the standby power system. The installers set up
and connect the various components of the system as specified in the system design plan.
The complexity of the standby system normally requires the special skills of qualified electricians,
plumbers, sheet metal workers, etc. to complete the various segments of the installation. This is
necessary so all components are assembled using standard methods and practices.
1.4.2 Safety Considerations
The transfer switch has been carefully designed to provide safe and efficient service when properly
installed, maintained, and operated. However, the overall safety and reliability of the complete system
depends on many factors outside the control of the manufacturer. To avoid possible safety hazards, make
all mechanical and electrical connections to the transfer switch exactly as specified in this manual. All
systems external to the transfer switch must comply with all applicable codes. Make certain all required
inspections and tests have been completed and all code requirements have been satisfied before
certifying the installation is complete and ready for service.
Verify that both power source voltages match the nameplate rating prior to installation.
1.5 Model Identification
If the transfer switch ever needs to be serviced, the distributor will need this information in order to
properly identify your unit from the many types manufactured:
• Model No. (Product Model)
• Serial No. (Product Serial Number)
• Spec. (Product Specification Letter)
