Step 4  Align the mounting bracket with the hole positions, insert bolt assemblies (flat washers, 
spring washers, and M12x40 bolts) into the holes through the mounting bracket, secure them 
using the shipped stainless steel nuts and flat washers, and tighten the bolts to a torque of 45 
N·m using an 18 mm socket wrench. 
 
The SUN2000 is delivered with M12x40 bolt assemblies. If the screw length does not meet the 
installation requirements, prepare M12 bolt assemblies by yourself and use them together with the 
delivered M12 nuts.
