1. UNPACKING: 

 

The mixer was carefully checked before leaving the factory.  Inspect shipping container and unit carefully for indication of 
improper handling.  If the unit has been damaged, make an immediate claim to the carrier. 

 

2. MOUNTING 

INSTRUCTIONS: 

 

The mixer is provided with five mounting feet for placement on a shelf.  An optional Rack Mount Kit (PA-RMK) is available 
for mounting in standard EIA 19” racks.  Refer to PA-RMK installation instructions (P83258) for mounting. 

 

CAUTION:  

These devices are not intended for use in hazardous locations as defined by the National Electrical Code (NEC). 

 

3. 

POWER AND GROUNDING (SEE FIGURE 1): 

 

The 115VAC line cord has a three-prong plug which should be plugged into a three wire grounded electric outlet.  It is very 
important to maintain the mixer ground for safe and trouble-free operation.  If there is no grounded electric outlet, connect earth 
ground of the AC line cord to a water or steam pipe. 

 

4. 

POWER SWITCH AND RECEPTACLE (SEE FIGURE 1): 

 

The ON/OFF power switch located on the rear panel controls both the internal power of the mixer and the accessory IEC female 
outlet. 

 

Note

:  The accessory to be attached and controlled by the ON/OFF switch must not exceed 3 Amps at 115VAC.
