• Do not use the equipment if it operates abnormally. Protection may be impaired. When in doubt, have the equipment 

serviced.

• Do not operate the equipment where explosive gas, vapor, or dust is present. Don't use it under wet conditions.
• Do not apply more than the rated voltage, as marked on the apparatus, between terminals or between any terminal 

and earth ground.

• When servicing the equipment, use only specified replacement parts.
• Use caution when working with voltages above 30 V AC rms, 42 V peak, or 60 V DC. Such voltages pose a shock 

hazard.

• To avoid electric shock, do not touch any bare conductor with hand or skin.
• Adhere to local and national safety codes. Individual protective equipment must be used to prevent shock and arc 

blast injury where hazardous live conductors are exposed.

• Special note: If a dangerous voltage is applied to an input terminal, then the same voltage may occur at all other 

terminals.
