7.GENERAL NOTES ON SERVICING TRANSFER SWITCH MECHANISM

DANGER!!!!

Arc Flash and Shock Hazard. Will cause severe injury or death.

Do not open equipment until ALL power sources are disconnected

This equipment must be installed and serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal Protective Equipment (PPE). Failure to do so may cause personal injury or death

Note: Refer to product drawings in sections 12, 13 & 14 for identification of Transfer Switch Mechanism style supplied with the Transfer Switch.

When performing any service work on the transfer mechanism, it is imperative that the following be observed:

7.1.To maintain mechanical integrity, ensure that:

•On T Style mechanisms, all limit switches are correctly adjusted to provide full travel of the power switching device toggles without exerting unnecessary forces associated with excessive travel. Ensure that power switching device travel far enough to reset any internal trip unit (it is more important for the toggle to go fully in the "off" direction, than in the "on" direction).

•Mechanical interlocking is correct when one power switching opens well before the other should close.

•All fasteners are adequately tightened.

•The operating linkages are not damaged or bent, and that all bearing points operate freely.

•On S style transfer switch mechanisms, check nylock nuts on bolt pivot points. Operation arms should move freely without excessive play.

7.2.To maintain electrical integrity, ensure that:

•All electrical connections, especially power connections, are clean and

adequately tightened. Corroded or loose power connections will cause destructive heating, and may cause premature tripping.

•All insulating devices are in place and in good condition.

PERFORMANCE TEST The interconnected system shall be evaluated to ensure compliance with the appropriate schematic drawings. The proper location of sensors and power cabling shall be determined. The grounding points of the system shall be verified to determine that ground paths do not exist that would bypass the sensors. The use of high-voltage testers and resistance bridges may be required. A simulated fault current is to be generated by a coil around the sensors. The reaction of the circuit-interrupting device is to be observed for correct response. The results of the test are to be recorded on the test form provided DANGER Arc Flash and Shock Hazard. Will cause severe injury or death 18.
