Storage

The switch should be placed in service immediately in its permanent location. However, if it must be stored for an indefinite period, it should be carefully protected against condensation, preferably by storage in a warm dry room. Switches for outdoor equipment should be stored in that equipment only when power is available and heaters are in operation, to prevent condensation.

The switch should be stored in a clean location, free from corrosive gases or fumes. In particular, protect the switch from moisture and cement dust, as that combination may be corrosive.

If the switch is stored for any length of time, it should be inspected periodically to ensure good mechanical condition.

Panel Cutouts and Clearances

Use the following information to prepare the equipment and assure proper clearances for installation and operation of the switch.

Figures 1 and 2 show the front-panel escutcheon cutout patterns and the locations of the switch mounting bolts. The standard door cutout dimensions require a trim plate on the switch. The optional dimensions are for flush front or nonhinged door construction and the trim plate may be omitted. Ventilation cutouts are required for stationarymounted switches rated 1600 A and larger and for drawout switches rated 2000 A and larger. Ventilation cutouts

not

are frame switches or for stationary-mounted 800 A frame switches.

Because of arc chamber venting, the minimum throughair distance from the top of the switch’s molded case to grounded metal for 800–2000 A switches is 4.50 inches [114 mm] in an area 5.31 inches x 16.00 inches [135 mm x 406 mm], centered over the vent screens. (Refer to outline drawings 10054370, Sheets 1–5, for details.)

For 2500–4000 A switches, the minimum through-air distance from the top of the switch’s molded case to grounded metal is 8.00 inches [203 mm] in an area 9.00 inches x 16.00 inches [227 mm x 406 mm], over the vent screens. (Refer to outline drawings 10055629, Sheets 1–7, for details.)

Closing the Switch

Close the switch contacts with either of the following methods:

• Depress the ON button on the front of the switch.

• Energize the (optional) Remote Close accessory by applying rated voltage to terminals 16 and 34 on terminal block B.

CAUTION:

If the switch latch is held in the tripped position by any of the following conditions and an attempt is made to close the main switch contacts, the mechanism will “crash” (the closing springs discharge with no motion of the switch contact arms). The switch has been designed and tested to withstand more than 100 crash operations, but repeated attempts to close a locked-out switch will damage the switch mechanism.

CAUTION:

the switch latch is held in the tripped position by any of the following conditions:

• The Bell Alarm with Lockout was not reset after a ground fault lockout.

• The Undervoltage Release is not energized.

The main switch contacts cannot be closed if

• The Key interlock or padlock is in the locked OFF condition.

• The draw-out interlock is engaged with the carriage between the TEST and T CONNECTED positions.

• The walking beam interlock or mechanical interlock is activated.

• The Shunt Trip with Lockout is energized. These conditions must be corrected before the switch

can be closed.

ATTENTION:

Operation

The Bell Alarm–Alarm Only provides normally open (NO) and normally closed (NC) outputs available at the terminal block on the right side of the switch, as illustrated in Figure 12. The outputs change state whenever a switch ground fault trip occurs. This trip can be caused by a ground fault condition detected by the Control Unit.

The Bell Alarm–Alarm Only accessory resets automatically, returning the outputs to their normal configuration, when the switch is reclosed. The Bell Alarm–Alarm Only can also be reset manually, before the switch is reclosed, by pressing the reset button on the front of the module.
