Features and benefits
Robust product design and testing - The generator is designed to operate under extreme environmental
conditions including cold weather starts at as low as -40 oF when equipped with the necessary accessories.
The generator is tested and certified per the latest EPA, UL and IBC Seismic standards and is capable of
meeting NFPA 110 requirements when equipped with the necessary accessories and properly installed.
Flexible exercise mode - The innovative, flexible exercise mode enables the generator to exercise at a
time, frequency and duration that suits the customer's preference - as little as 2 minutes every 6 months -
reducing unnecessary fuel consumption, emissions and noise.
Advanced enclosure design - The aesthetically appealing enclosure incorporates special designs that
deliver the quietest generator of its kind.
Aluminum material plus durable powder coat paint provides the best anti-corrosion performance. The
generator set enclosure has been evaluated to withstand 180 mph wind loads in accordance with ASCE
7-10. The design has hinged doors to provide easy access for service and maintenance.
Control system - The PowerCommand® electronic control is standard equipment and provides total generator set
system integration including automatic remote starting/stopping, precise frequency and voltage regulation, alarm
and status message display, output metering, auto-shutdown at fault detection and NFPA 110 level 1 compliance.
Self-diagnostics and easy service - The PowerCommand® electronic control provides industry- leading self-
diagnostic capabilities. In addition, critical components of the generator are designed to ensure service and
preventive maintenance can be completed in a short period of time.
