ENCLOSURE CONSTRUCTION

Dimension “A” Minimum

n

Applies to Bulletin 1494F only.

NOTE: The above figure depicts a right-hand Master
Installation. The left-hand Master Installation is a mirror
image of the right-hand installation.

A typical Master Auxiliary Installation is shown in the

figure above with one Master Kit and two Auxiliary Kits. A
maximum of 10 Auxiliary Kits can be employed with one
Master. The dimensions would simply continue. Further,
the location or position of these Kits could be arranged in
any order, so that the Master Kit could be between Auxil-
iary Kits or to the left of Auxiliary Kits; or the Auxiliary Kits
could be all right-hand, left-hand, or any combination of
both types.

Enclosure Instructions

CAUTION: The Door Hardware Kits installed on all the
auxiliary enclosure doors require a slightly different drilling
pattern from that used for Catalog Numbers 1494F-L4,
1494F-LL4, 1494V-L3, and 1494V-LL3. The 0.406 (10.3)
diameter hole located 2-3/8 in. (60.5) up from the 0.750
(19) diameter door handle mounting hole should be omit-
ted. In addition, it is unnecessary to add the two tapped
holes to the top locking bar since the defeater actuator
lever need not be attached where no disconnect switch or
circuit breaker is installed. It is also unnecessary to install
the door catch. The door catch and defeater actuator lever
and the screws that attach these parts may be discarded.

1.

Provide mounting holes on the enclosure’s upper
flange lip for the Master Interlock Kit as indicated in
Figure 2.
NOTE: The Master Kit is always fastened to the
door opening having the disconnect switch or circuit
breaker.

2.

Provide mounting holes on the enclosure’s upper
flange lip and side flange lip for the Auxiliary Kit(s) as
indicated in the Figure 2.

Connecting Rod Instructions

1.

Establish the length(s) of the connecting rod(s) from
Master Kit to Auxiliary Kit(s) by measuring Dimension
“B” and subtracting 1-11/16 in. (43). Cut to size.
NOTE: The 3/8 in. (9.5) square rod(s) is not sup-
plied with these kits.

2.

Establish the length(s) of the connecting rod(s) from
Master Kit to Auxiliary Kit(s) by measuring Dimension
“C” and subtracting 1-11/16 in. (43). Cut to size.
NOTE: The 3/8 in. (9.5) square rod(s) is not sup-
plied with these kits.

Lifting Rod Instructions

1.

Determine the length(s) of the Lifting Rod(s) from the
upper auxiliary mechanism(s) to the lower auxiliary
mechanism(s) by determining Dimension “D” and:
A.

Subtracting 8-7/8 in. (225) when using Assembly
Method Number 1.

B.

Subtracting 7-3/4 in. (197) when using Assembly
Method Number 2.

2.

Cut rod to size.

3.

Locate and provide holes as indicated in the figure
above.
NOTE: The standard mill rectangular Lifting Rod is
not supplied with these assemblies.

NOTE: Dimensions shown in parentheses are in millimeters.
