Auto-Latch Features
The automatic door latching feature furnished on the main
doors provides ease in opening and closing of the doors. Fea-
tures of the Auto-latch system are:
• Automatic 3-point latching upon door closure. See Figure 22.
• After unlatching on opening, the door is automatically set for
latching upon door closure.
• A recessed, flush-mounted, stainless steel pocket contains
the padlock and security bolt.
• To discourage tampering, the padlock must be removed in
order to raise protective cover and gain access to security
bolt.
• A closed, latched, Auto-latch door can successfully with-
stand a "pull" greater than 600 pounds at any point on the
door.
Auto-Latch Operation
Opening:
1. Remove padlock and raise protective cover exposing security
bolt. (Figure 24)
2. Using a standard 9/16 inch socket for hexhead security bolt or
standard pentahead socket for pentahead security bolt, rotate
the captive actuator bolt head 60° in either direction to release
latching mechanism. (Figure 25)
3. Open door and secure with door keeper. (Figure 23)
Closing:
1. Lift up door keeper and close door by pushing briskly. Mecha-
nism will automatically latch.
2. Install protective cover and install padlock.

Caution: It is not necessary to apply
torque on the bolt once the door is
unlatched. The bolt is not removable. A
force of 25 to 30 ft. - pounds will cause a
failure.

Maintenance
Federal Pacific switchgear does not require routine mechani-
cal or electrical maintenance. However, the following are some
recommendations for enhancing continued service of the equip-
ment.
1. Yearly mechanical exercising of the switch is recommended.
Warning: The switchgear must be completely de-energized from
all sources before any attempt is made to enter switchgear.
2. Check for cleanliness generally, but particularly for accumu-
lation of any foreign material on insulators.
Caution: Do not put grease on switch probe or puffer.
3. If the switch is closed on a short circuit within the making
capacity rating and the short circuit is cleared by circuit
breakers or fuses, the switch will not sustain damage which
would require major repairs. However, the switch should be
inspected before returning to service to determine switch
condition.
