MULTIPLE DOOR INTERLOCK
METHOD OF ASSEMBLY
The multiple door interlock hardware kits are to be
used with Catalog Numbers 1494F-L4, 1494F-LL4,
1494V-L3, and 1494V-LL3 door hardware kits to provide
interlocking of Auxiliary Doors with the Master Door for
NEMA Type 1 and Type 12 enclosures.
There are two possible methods by which the Master
and Auxiliary Interlock Kit can be installed. Certain condi-
tions dictate which method to use.
Use Assembly Method Number 1: On all normal
installations.
Use Assembly Method Number 2: Only when the con-
necting rod between the Master Kit and Auxiliary Kit(s)
passes over the disconnect switch or circuit breaker, as
shown in the figure above, and one of the following condi-
tions exists:
• Dimension “E” on Page 1 of the Circuit Breaker
Operator Installation Instructions (Publi-
cation 1494D-5.0) is less than 4-3/8 in. (111) for
devices rated at 15…70 Amperes;
• Dimension “S” on Page 1 of the Flange Mounted
Disconnect Switch Installation Instructions (Publi-
cations 1494F-5.0, 1494M-800, and 1494M-801)
is less than 4-3/8 in. (111) for 30 and 60 Ampere
devices and less than 6 in. (152) for 100 Ampere
Devices;
• Dimension “C” on Page 1 of the Circuit Breaker
Operator Installation Instructions (Publi-
cation 1494V-5.05) is less than 5-1/2 in. (140) for
devices rated at 15…70 Amperes; or
• Dimension “C” on Page 1 of the Disconnect
Switch Installation Instructions (Publi-
cation 1494V-5.0) is less than 5-1/2 in. (140) for
30 and 60 Ampere devices.
NOTE: The purpose of Assembly Method Number 2 is to
move the connecting rod to a higher position which will
provide greater electrical clearance between it and the dis-
connect switch or circuit breaker.
When the method of assembly has been determined,
it is required that both the Master Kit and the Auxiliary
Kit(s) employ the same method.
NOTE: Dimensions shown in parentheses are in millimeters.
