SAVE THESE INSTRUCTIONS TABLE OF CONTENTS This manual contains important instructions that INTRODUCTION should be followed during installation and maintenance GUIDE TO PRODUCT SAFETY of the generator and batteries. BASIC INFORMATION Description Read and understand all instructions in the manual DSE 7110 Description before starting and operating the generator set.
IMPORTANT SAFETY INSTRUCTIONS 2. FIRE HAZARD - Natural gas and L.P. present a hazard of possible explosion and/or fire. a. b. SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. 3. Read and understand all instructions in the manual before starting and operating the generator set. This engine generator set has been designed and manufactured to allow safe, reliable performance.
TESTING POLICY: Before any generator is shipped from the factory, it is fully checked for performance. The generator is loaded to its full capacity, and the voltage, current, and frequency are carefully checked. Rated output of generators is based on engineering tests of typical units, and is subject to, and limited by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of the applicable engines. fuel.

CAUTION – PERSONAL DANGER CAUTION - NEVER dispose of a battery in a fire. The battery is capable of exploding. CAUTION - DO NOT open or mutilate the battery. Released electrolyte is known to be harmful to the skin and eyes and to be very toxic. These engine generator sets are all NEGATIVE ground. Be very careful not to connect the battery in reverse polarity, as this may short circuit the battery charging system on the engine.
To wire the automatic transfer switch into the existing wiring, first determine which circuits will be on the emergency load circuit. If the entire load is to be transferred, the transfer switch can be wired in directly after the watt-hour meter and the service entrance, providing the service entrance ampere rating is within the transfer switch’s rated capability.
See the manual shipped with the Automatic Transfer Switch for connection locations in the switch. Connections in each switch will vary depending on the type of switch and the manufacturer. GROUNDING A grounding lug has been provided on the engine generator set to grounded to earth ground if required. Check with your local codes. Generally a 6 foot copper rod driven into the earth will provide a proper earth ground. D.C.
ASCO 165 UL SWITCH Your DC connection points in the ASCO 165 ATS are terminals “4” and “5 on the interface terminal block. ASCO 300 UL SWITCH Your DC connection points in the ASCO 300 ATS are terminals “14” and “15”. Depending on the size of the switch they are located in different locations. See next page: D. AC INTERFACE CONNECTOR - This connector is used to interface with the AC generator end. It provides the controller with the voltage, amperage and frequency reading for the display. E.

panel. The voltage should also be checked between the hot terminals (G1 and G3) and the G-N to be certain of a balanced voltage output and a solid neutral connection. The voltage between G1 and G-N should be about 120 volts AC (277 on 480 units). The same approximate voltage should be found between terminals G3 and G-N (120 volts AC).
