Installation
Access to Interior
Step 1
TO OPEN DOORS:
Access to the interior of S&C Pad-Mounted Gear is controlled
by the S&C Penta-Latch® Mechanism, which must be opened with a pentahead socket
wrench or tool except when hexhead actuators (Catalog Number Suffix “-B1” or “-B2”)
are specified . The latching mechanism is coordinated with the provisions for padlocking
such that the mechanism can be unlatched only after the padlock has been removed, and
the padlock can be installed only after the door has been securely closed and completely
latched .
Use a pentahead socket wrench or tool (a hexhead socket wrench or tool when Cata-
log Number Suffix “-B1”or “-B2” is specified) to unlatch the Penta-Latch Mechanism by
rotating the actuator counterclockwise approximately 60º against spring resistance until
a distinct “click” is heard and the actuator reaches its stop . Refer to Figure 2 . This single
motion unlatches the mechanism and recharges the latching spring for the subsequent
closing operation . Pull the door open and secure it with the door holder .
NOTICE
Do
not
force doors open .
Forcing a door open can damage the latching
mechanism.
If optional key interlocks are furnished, correctly position the interlocks so the
doors can be opened .
For double-door models of pad-mounted gear, the left-hand door is secured closed
by a rotating latch and is overlapped by the right-hand door which is equipped with the
Penta-Latch Mechanism . The left-hand door can be opened after opening the right-hand
door and disengaging the rotating latch . To disengage the latch, rotate it upward . See
Figure 3 on page 7 .
