CAUTION
Do not apply any undue force when attempting to
open a door . The use of undue force may damage
the latching mechanism . If optional key interlocks are
provided, be sure the interlocks are in their correct
positions to allow door opening .
Follow these steps to open the enclosure:
STEP 1.
Access to the interior of Manual PMH
Pad-Mounted Gear is controlled by the
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. The padlock can be installed
only after the door has been securely closed and
completely latched.
(a) Use a pentahead socket wrench or tool
(a hexhead socket wrench or tool when
catalog number suffi x “-Bl” or “-B2” is
specifi
ed) to unlatch the Penta-Latch
Mechanism by rotating the actuator
counterclockwise approximately 60°
against spring resistance until a distinct
“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.
(b) Pull the door open and secure it with the
door holder. See Figure 3.
(c) For double-door models of pad-mounted
gear, the left-hand door is secured by a latch
and is overlapped by the right-hand door
equipped with the Penta-Latch Mechanism.
The left-hand door can be opened after (1)
opening the right-hand door, (2) removing
the tie wrap that secures it for shipment, and
(3) disengaging the latch by rotating the
latch upward. See Figure 4 on page 8.
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.
