Handling Precautions For Silicon-Containing Spray

When a silicon-containing lubricant is used, rust inhibitor or glazing agent adheres to the electrical contact of the relay or switch, which may produce silica dioxide (SiO2). This may cause poor connection.

• Never spray directly to the electrical equipment.
• When using the spray close to the electrical equipment, always put the cover on it. Special care must be exercised especially when using the spray to the locations shown in the Fig 1 below and their surrounding areas.

• If the residual silicon remains in the vicinity of the electrical equipment after the spray has been used, the vaporized silicon stands around the electrical equipment and it may adhere to electrical contact. After using the spray, be sure to wipe the silicon off with a cloth.
• Even when using the spray to the place away from the electrical equipment, the droplet of the spray may be splashed to the periphery. Use as small amount of spray as possible, and take care not to splash the silicon to the periphery.
  NOTE: The "silicon" used in this section refers to "silicone", that is, silicon polymer.
