Kohler 3.5CFZ, 4CZ, 5CFZ, 6.5CZ installation manual Safety Precautions and Instructions

Page 4

A generator set, like any other electro-mechanical device, can pose potential dangers to life and limb if improperly maintained or imprudently operated. The best way to prevent accidents is to be aware of the potential dangers and to always use good common sense. In the interest of safety, some general precautions relating to the operation of a generator set follow. Keep these in mind. This manual contains several types of safety precautions which are explained below.

DANGER

Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the warning is ignored.

WARNING

Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the warning is ignored.

CAUTION

Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the warning is ignored.

Safety decals are affixed to the generator set in prominent places to advise the operator or service technician of potentially hazardous situations. The decals are reproduced here to improve operator recognition and thereby increase decal effectiveness. For a further explanation of decal information, reference the accompanying safety precautions. Before operating or servicing the generator set, be sure you understand the message of these decals. Replace decals if missing or damaged.

NOTE

Note is used to notify people of installation, operation, or maintenance information that is important but not hazard-related.

Can cause severe injury or death.

Do not operate generator set without all guards and electrical enclosures in place.

Hazardous voltage can cause severe injury or

death. Wherever electricity is present, there is the hazard of electrocution. Take the same precautions with electrical appliances in your craft that you would observe in your home. Open main circuit breaker on all power sources before servicing equipment. Make sure unqualified persons, especially children, cannot gain access to your set— keep the compartment door locked or securely latched at all times. Be sure that generator is properly grounded. Never touch electrical leads or appliances with wet hands, when standing in water, or on wet ground as the chance of electrocution is especially prevalent under such conditions.

Hazardous voltage can cause severe injury or

death. Use caution when handling the capacitor; possible electrical shock can result. Discharge capacitor by shorting terminals together.

Hazardous voltage can cause severe injury or

death. Short circuits can cause bodily injury and/or equipment damage. Do not contact electrical connections with tools or jewelry while adjustments are made. Remove wristwatch, rings, and jewelry that can cause short circuits.

Hazardous “backfeed” voltage can cause severe

injury or death. Do not connect to any building/marina electrical system without connecting through an approved device and after building main switch is open. Backfeed connections can cause serious injury or death to utility personnel working to repair a power outage and/or personnel in the vicinity. Unauthorized connection may be unlawful in some states and/or localities. A ship-to-shore transfer switch must be installed to prevent interconnection of generator set power and shore power.
