HAZARDOUS ENVIRONMENT

RISK OF EXPLOSIVE ATMOSPHERE.

De-energize all relays and connections before placement or removal.

Take precautionary measures to avoid electrostatic potential, especially on plastic

components.

Installations and maintenance tasks performed in potentially hazardous areas must be performed only

after the area has been verified to be free of hazardous materials, atmospheres, and conditions.

The following situations could cause a spark enough to ignite an explosion:

• Potential of electrostatic discharge on plastic components, or

• Removal or placement of an energized connection.
