Chapter 5 Door Latches, Operator Handles, and Unit Interlocks
Door Latches There are two types of door latches available for the 2500 MCC: quarter-turn door
latches and ArcShield door latches. Both latches are available with T-handles.
Quarter-turn Door Latches
Latches are provided on each unit door to hold the door
closed and isolate the column. You can rotate the door latches
by using a standard slotted screwdriver in the head slot.
Open the door latches as follows.
1. Rotate each door latch a quarter turn (90°) until its
head slot is horizontal.
2. Open the door once all latches are in the open position.
Close and lock the door latches as follows.
1. Close the door.
2. Using a slotted screwdriver, rotate each door latch a
quarter turn (90°) until all slots are vertical.
ArcShield Door Latches
ArcShield door latches are spring-loaded to
allow pressure relief and keep the doors from
detaching from the structure.
Follow the same procedures in the Quarter-
turn Door Latches to open or close a door
with ArcShield door latches.
IMPORTANT ArcShield door latches are spring-loaded. When closing a door, push in each
latch as you turn it so it locks correctly for ArcShield protection.
