Power Break® II Devices 

Draw-Out Device Installation 

Installing the Device 

Use  the  following procedure  to  install the  draw-out  device 
into the substructure. 

Attach  the  Lifting  Bar,  catalog  number  TDOLB,  by 
locating  the  hooks  on  the  bar  beneath  the  shoulder 
studs of the device, as illustrated in Figures 4 and 5.
Pull  out  the  substructure rails  until  they  drop  into  the 
horizontal locked position. Lower the device so that the 
grooves in the rollers drop over the rails.
Make sure the grooves in all rollers straddle the rails, as 
illustrated in Figure 6, then remove the Lifting Bar and 
push the device into the substructure until it stops in the 
DISCONNECTED  position.  Then  lift  the  rails  and  push  
them in to the stored  position.

CAUTION: 

 The  device  must be

 

OFF before it is connected. 

If the device is charged, press the ON  button to close the 
device  contacts,  then  press  the  OFF  button  to  open 
the contacts. 

Engage the   1/2 -  inch square end of the racking shaft 
with the supplied wrench, catalog number TDORT, and 
rotate the  shaft clockwise to  draw  the  device into  the 
TEST or CONNECTED position, as illustrated in Figure 7. 
The compartment position indicator is shown in Figure 
8.

NOTE:

  If  the  device does  not  fit  the  structure, check  the 

rejection relationship, illustrated in Figure 8, to verify that a 
correctly rated  device  is  being  installed. Table  1  lists  the 
correct draw-out substructure for each device frame. 

NOTE:

  Si  le  mécanisme  ne  rentre  pas  dans  le  berceau, 

vérifier  le  détrompeur  illustré  dans  les  figure  8,  qui 
empêche l’insertion d’un mauvais calibre de mécanisme. La 
Table  1  définis  le  berceau  convenable  à  chaque  taille  de 
mécanisme.

ATTENTION: 

Le mécanisme doit être à OFF avant qu’il ne 

soit embroché. Si  le  ressort de  fermeture de  mécanisme 
est chargé, fermer les contacts de mécanisme par action 
sur  le  bouton  ON,  puis  appuyer sur  le  bouton  OFF  pour 
ouvrir les contacts.
