To install the PMK 550 in a PoleVault system:  
Figure 1. PMK 550  
1. Remove the four cover screws from the center (see figure 1).  
Slide the two halves apart and remove them from the base plate.  
NOTE: If the PoleVault switcher and its power supply are  
already installed, go directly to step 5.  
2. To mount the PoleVault switcher, place the mounting plate, with the  
raised tabs upwards, on top of the switcher top and pass the two  
supplied 4-40 x 3/16 inch screws into the top of the switcher (see  
figure 2, top). Secure the mounting plate but do not overtighten.  
3. Hook the combined plate and switcher into the PMK 550 base plate.  
Secure it to the base plate with two screws.  
NOTES:  
Any installed switcher should be secured to the plate  
in an upside down position so that when the plate is  
rotated to hang from the ceiling, the device will be in  
its correct orientation (see figure 2, bottom).
