Procedures for Removal and Installation of Printed Circuit Board
STATIC ELECTRICITY HAZARD AND PREVENTION
Static electricity can easily damage the electronics of your telescope. Great care should
be observed in the handling of the electronics to prevent damage. Note that it is very
easy to generate several thousand volts of static electricity on plastic surfaces just by
handling them. This includes plastic bags, bubble wrap, styrafoam packing materials, as
well as indoor carpet. Take the following precautions:
• Work on metal or wooden surfaces.
• DO NOT work in an area with a rug on the floor.
• Be sure to discharge yourself by touching the metal of the telescope BEFORE
handling the electronics.
• DO NOT put the printed circuit board in a plastic bag unless you have the type
designed for holding electronics (conductive plastic bags).
• DO wrap the printed circuit board in aluminum foil before packing it in a box if
you don't have a conductive plastic bag.

  • Page 7 R.A. Motor Removal 1. Disconnect the R.A. Motor cable (7 Pin connector) from the Printed Circuit Board. 2. Remove the 2 hex (Allen) screws holding the RA Motor assembly to the drive base. Be very careful you don’t drop the hex screws down into the base as it’s very difficult to retrieve them, and you could jam the worm gear.
  • Page 8 R.A. Motor Assembly Installation 1. Align the RA motor assembly with the two threaded mounting holes. Note that some motor assemblies have a step in the base of the mount which requires a special mounting plate. We recommend you smear some grease on the base and mounting plate to hold them together while installing the motor assembly.

  • Page 10 Pic 5 Declination Motor Installation 1. Pass the power cable of the motor assembly through the opening I the fork arm and plug it into the RJ-45 jack inside the fork arm. 2. Center the motor assembly over the two threaded mounting holes in the fork arm housing.
  • Page 11 6. Semi-tighten the left mounting screw, push up on the motor block to level the assembly and tighten the right mounting screw. Tighten the left mounting screw. Check the worm gear and worm wheel meshing to ensure a good fit. 7.
