Access to the Interior
STEP 1.
To open the doors
:
Access to the interior of
S&C Pad-Mounted Gear and its low-voltage
control compartment 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 suffi x “-B1” or “-B2”) are specifi ed. The
latching mechanism is coordinated with the
provisions for padlocking so 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 catalog
number suffix “-B1” or “-B2” is specified) to
unlatch the Penta-Latch Mechanism by rotating
the actuator counterclockwise approximately
60 degrees against spring resistance until a dis-
tinct click is heard and the actuator reaches its
stop. See 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. See Figure 3.
NOTICE
Do not force the doors open . Forcing a door
can damage the latching mechanism .
If optional key interlocks are furnished,
correctly position the interlocks so the
doors can be opened .
Figure 2. To unlock the doors, turn the pentahead socket wrench
60° counterclockwise against spring resistance until a “click”
is heard and the wrench reaches its stop.
