Application 

 

 

This manual is designed to help you install the MaxPlus™ 211 Option Spindle amplifier. 

 
 

Unpacking and Inspection 

 

 

Carefully unpack the amplifier and inspect it for visible damage. Check items against the 
packing list. Report any missing or damaged items to your supplier.  

 
 

Warranty and Service 

 

 

The amplifier is warranted to be free from defects in workmanship and materials for a period 
of two years from the original shipment by MTS Automation. 
 
During the warranty period, a defective amplifier unit will be repaired or replaced as outlined 
below. 
 
Before requesting return authorization, please try to verify that the problem is within the 
amplifier, and not with external devices. 
 
To arrange for repair or replacement, please contact: 

 

MTS Automation Customer Service 

(507) 354-1616 
(800) 967-1785 

Monday–Friday, 8:00–4:30 Central Time 

 

• 

You must provide the model and serial number from the labels on the amplifier. 

 
• 

You must provide an explanation as to why the unit is being returned. 

 
• 

You will be issued a return authorization number which must be marked on the return shipment and 
on all correspondence.
