EntelliGuard R Circuit Breaker Retrofill AKD-8 Installation Manual          DEH41549 R05

 

Install Door Interlock System 

 

 

It must be ensured that the supply power 
to the compartment is turned off/ 
compartment is de-energized for all the 
incoming and outgoing circuits of the LVS 
prior to any work being conducted on it. 

 

During the installation and related work 
on the equipment, it must be ensured 
that the operator is using the prescribed 
PPE for the specified tasks.

 

 

 

Ensure only qualified personnel install, operate, service, and maintain all electrical 
equipment. 

 

 

Details regarding installation of the door interlock system are shown below in 

Figure 44

, 45 and

 46

 

Figure 44. AKD-8—Door Interlocking Components (Model 1) 

 

 

 

Racking stroke of legacy = 4.25”. Racking stroke of Retrofills = 2.75”. 

 

Racking stroke of the Retrofills is equal to that of AKR30S. 

 

Same mounting bracket used for all AKR breakers in AKD8, depending on SKU the mounting holes are 
decided on. 

 

Provisions for fixing the door interlock are already present on the mounting bracket.  

 

Door interlock system of AKR30S can be used for Retrofills. 

 

Remove existing activator and replace with new activator shown.  

 

For AKR30S, existing door interlock suffices. No changes needed.
