description 
The XE2-HK is a kit containing a heatsink and mounting hardware for field installation of a 
standard heatsink onto Xenus Plus XE2 model servo drive. To order an XE2 drive with heatsink 
fitted at the factory, add “-H” to the model part number. 
installation 
1) Place the heatsink fins-down on a work surface. 
Orient the heatsink so that the edge with part 
number is away from you. The hole for the XE2 
grounding lug should be to your left. 
2) Remove the clear protective film from the thermal 
material and discard it. Place the thermal material 
onto the heatsink in the placement area which is 
marked with four white “L”.  
Apply light pressure to ensure that the thermal 
material is flat. 
3) Peel the white protective layer away from the 
thermal material. Do this slowly from one corner 
so as not to lift the thermal material from the 
heatsink. 
4) Align the XE2 as shown and lower onto the 
heatsink. 
If needed to adjust the position, lift it away from 
the thermal material and lower onto the heatsink 
again. 
5) Install the four mounting screws with flat washers 
 and tighten evenly. Torque to 17.8 lb-in (2.0 Nm) 
maximum. 
Note: If alignment markings 
are not on heatsink, use 
these dimensions to place
