Safety Precautions Before operating the transfer switch, read the Opera­tor's Manual and become familiar with it and your unit. Safe and efficient operation can be achieved only if the transfer switch is properly operated and maintained. Accidents are caused by failure to follow fundamental rules and precautions.

Throughout this manual you will observe symbols, shown below, which indicate potential dangers to the operator, service personnel, or the equipment itself. Read the manual carefully and know when these condi­tions exist. Then take the necessary steps to protect

, personnel and the equipment.

�DANGER This symbol warns of immediate hazards which will result in severe

personal injury or death.

� G I This symbol refers to a hazard or WARNIN unsafe practice which can result in severe personal injury or death.

I I This symbol refers to a hazard or ACAUTION unsafe practice which can result in personal injury or product or property damage. ELECTRICAL SHOCK WILL CAUSE SEVERE PER­SONAL INJURY OR DEATH.

The automatic transfer switch has components with high voltages which present serious shock hazards. For this reason, read the following suggestions.

ii

• Keep the automatic transfer switch cabinet closed and locked. Make sure only authorized personnel have the cabinet keys.

• Before performing maintenance or making adjust­ments, move the operation selector switch on the generator set or automatic transfer switch to STOP. Then disconnect the starting batteries [(-) lead first] of the generator set and remove AC line power from the automatic transfer switch. If instructions state otherwise, use extreme caution due to the danger of shock hazard.

• Use rubber insulating mats placed on dry wood platforms over floors that are metal or concrete when working on any electrical equipment. Do not wear damp clothing (particularly wet shoes) or allow skin surfaces to be damp when handling elec­trical equipment.

• Jewelry is a good conductor of electricity and should be removed when working on the electrical equipment.

• Do not work on this equipment when mentally or physically fatigued, or after consuming any alcohol or drug that makes the operation of equipment unsafe.

• Copy and post these suggestions in a prominent area of the transfer switch.

Section 1 II General Information

ABOUT THIS MANUAL

This manual provi des service i nformation specific to Onan L T II series transfer switches. Both standard and option variat ions are i ncluded i n subjects covered. When performing troubl eshooti ng, adjust­ment, and repair procedures, remember the transfer swi tch, generator set, and commercial power are al l interdependent. The serviceperson must t herefore possess thorough k nowledge of transfer switch pri n­c i p l es, and basi c k nowledge of e l ectrical fun­damentals.

. . The following two pages show the model numbering ... system for starting spec H units and the older spec G

. .. units.A typical model number is given for each spec and the meaning of the code segments.

During periods of normal operation, read a l l service and operat ing i nstructions appl icable to your site equi pment. This wi l l al low you to more effectively remedy a faul t con d it ion when i t occurs. When per­formi ng any servi ce procedures, observe a l l cautions and warni ngs in t h is manual and on transfer switch.

The transfer s\,vitch must alv'Jays mai nta i n com­p l iance with any appl icable codes and standards. Improper servici ng can create an unsafe instal lation that might cause serious personal i njury or death, or damage to the equi pment.

MODEL NUMBER SYSTEM

Always suppl y the complete Model number, Spec number, and Serial number as shown on the transfer switch nameplate (Figure 1-1) when contacting an Onan Dealer or Distributor. This information is neces­sary to identify your transfer switch when ordering replacement parts.
