Receiving
Before being packaged for shipment from the factory, the con-
trol unit is given a thorough electrical test and mechanical
inspection. Upon receipt, inspect the package for damage dur-
ing shipment. After unpacking, inspect the equipment for con-
cealed damage which may have occurred in transit.
If damage or loss is discovered, file a claim with the carrier who
delivered the control unit. As much identification as possible
should accompany the claim, together with a full description of
the damage. When filing a claim with the carrier, photographs
of the damage are very helpful.

1. Adding To A Blank Unit Space
a. Remove blank door by withdrawing hinge pins, close door
halfway and slide off hinges.
b. Remove door gasket angle (intermediate angle, see Parts
Illustration on page 7) by removing the screw which fastens
it to the Separator Angle and tipping slightly to remove
formed tab at top from slot in shelf bracket above.
c. If necessary, install unit support assembly by inserting shelf
brackets at a slight angle into the appropriate holes in the
vertical bus support angle and snapping into place. Secure
support assembly with the two screws provided.
screw fastens the right-hand shelf bracket to the vertical bus
support angle. The second screw fastens the separator
angle to the left side of the structure. See Figure 2.
d. Remove appropriate unit stab hole covers.

engagement by sliding over stop on shelf brackets with the
supplementary installation handle on bottom barrier plate
and closing racking lever in top barrier plate. Engage locking

tab for top mounting holes.
h. Follow procedures for connecting outgoing power and con-
trol wiring. Mount pilot device panel on door.
i.
Close door and perform all pre-operation check procedures.
2. Replacement With A Unit Of The Same Size
a. Put disconnect operating handle in the PARK position (Figure
13). (Interlocking mechanism will not permit removing or
inserting the unit with the handle in the ON position.)
b. Unscrew locking latch at lower left of the unit. Rotate latch
until it disengages the separator angle.
c. Transfer pilot device panel from door to slot on unit. Remove
from door by rotating cam counterclockwise (do not loosen
cam screw).
d. Open vertical wireway door.
e. Move unit to "Test" position by opening racking lever in top
barrier plate while pulling on the supplementary installation

3. Rearranging Control Units Of Different Sizes
a. Remove all necessary existing units and doors including
structure-side hinge as described above, steps 2a-g.
b. Remove all necessary intermediate angles as described
above, step 1b.
c. Remove all unit support assemblies by unfastening the
