If personnel must stand on metal or concrete while installing, operating, servicing, adjusting or repairing this equipment, place insulative mats over a dry wooden platform. Work on the. Keep a fire extinguisher near the generator at all times. Do NOT equipment only while standing on such insulative mats.General Information IDENTIFICATION RECORD NOTE: For actual information related to this particular model, please DATA LABEL refer to the Manual Drawing Listing located at the end of this manual, or to the data label affixed to the unit.
Every generator set has a DATA LABEL that contains important information pertinent to the generator.Equipment Description EQUIPMENT DESCRIPTION COOLANT RECOMMENDATIONS This equipment is a revolving field, alternating current Stationary Use a mixture of half low silicate ethylene glycol base anti-freeze Emergency Generator. It is powered by a gaseous fueled engine and deionized water. Cooling system capacity is listed in the operating at 1800 rpm for 4-pole direct drive units, 3600 rpm for specifications.Engine Protective Devices ENGINE PROTECTIVE DEVICES OVERCRANK SHUTDOWN The Stationary Emergency Generator may be required to operate After a prespecified duration of cranking, this function ends the for long periods of time without an operator on hand to monitor cranking if the engine has failed to start.

The voltage and phase The Stationary Emergency Generator is designed to supply are described on the generator data label.General Information Figure 7.4 — Stator Power Winding 3-PHASE ALTERNATORS ('DELTA' CONFIGURATION) Connections - 3-phase, 120/208V (6 Lead) The Stationary Emergency Generator is designed to supply 3-phase electrical loads. Electric power is produced in the alterna- tor power windings.
These windings were connected at the factory INTERNAL CONNECTIONS to the main circuit breaker with a “Delta”.Control Panel CONTROL PANEL INTERFACE Upon power up, this controller will go through a system self test which will check for the presence of utility voltage on the DC circuits. This is done to prevent damage if the installer mistakenly USING THE AUTO/OFF/MANUAL SWITCH connects AC utility power sense wires into the DC terminal block.Control Panel ACTIVATION CHART CHOOSE LANGUAGE TROUBLESHOOTING Display Reads: Use ARROW keys to scroll to desired lan- If the wrong language is chosen, it can be guage.
