 +The Long and Short connection cables are similar and can be interchanged if the user needs. The Long cable is usually used to connect to the main unit but this is not mandatory; any of the cables can be used.
  
-  * 1x USB to UART converter (to connect the PC to the External bus port, the fastest communication option with the lowest latency) 
-  * 1x Power + Data hub board to inject power into the bus 
-  * 1x 12V Power supply 
-  * 2x USB adapter to Power + Data hub cables 
-  * 2x Power + Data hub to RH8D unit cables

 The hand is assembled by means of 8 screws located on the back (“wrist”) position. These screws are designed with common spacing in mind, being compatible with assembly on Robotis Dynamixel Pro Series (such as used in Thor-Mang). The hand is assembled by means of 8 screws located on the back (“wrist”) position.

 Assembly screws are already pre-assembled (in green). Remove them, including the washers. Pay attention to NOT remove the screws in red or any other screws as they are structural to the hand assembly. Assembly screws are already pre-assembled (in green).

-The wrist rotation has slightly over 180º of range. Therefore, for correct assembly, rotate central hub so that triangle in center part aligns with top triangle in outer shell. This corresponds to neutral angle. Wrist will rotate 90 degrees left and right from this position+The wrist rotation has aproximately 180º of range. Therefore, for correct assembly, rotate central hub so that triangle in center part aligns with top triangle in outer shell. This corresponds to neutral angle.

-Use supplied M2.5x16mm screws to mount unit. Take care to notice that screws must enter the unit between 12mm and 16mm. This means supplied screws can be used with mounts up to 4mm thick. If thicker mount is to be used, please use longer screw accordingly. +
- +
-After this step and without applying power, manually rotate unit to confirm assembly was performed correctly. Unit should turn around 180º total.+
  
-IMPORTANT:+Use the pre-assembled M2.5 bolts to mount the unit to your robot.
  
-When tightening screws do not push them inScrews should be tightened by rotation only.+**IMPORTANT:** Bolts must enter the unit between 12mm and 16mmAny longer will damage the internals of the unit and may prevent correct rotation of the Wrist; any shorter and appropriate fixation may not be provided.
  
-BEST PRACTICE: we suggest applying thread lock glue to the screws holding the handUse of the washers is recommended but not necessarydepending on the mount material+After this step and **without applying power, manually rotate unit to confirm assembly was performed correctly**If you feel any blockage within the 180 degree rangeplease consult with our technical team through the email support@seedrobotics.com **before powering and using** the unit.
  
-Complete the assembly by connecting a Dynamixel cable from the hand to the nearest interface (servo or PC adapter).+** FINAL NOTES:** 
 +  * When tightening screws __do not press or push them in__. Screws should be tightened by rotation only. 
 +  * Use of the washers is recommended but not essencial, depending on the mounting bracket and your own individual needs. 
 +  * Complete the assembly by connecting the appropriate cable to the main connector at the back of handSee [[common:connectorpinouts_connectionoptions|Connection Diagrams and Connector Pinouts]]
