Removing the Controller cover
Important:
Electrostatic discharge can damage controller components. Use proper
electrostatic discharge precautions during installation, setup, and servicing to avoid damaging
the controller.
Important:
Disconnect all power sources to the controller before you remove the cover
and change the position of any jumper on the controller. Failure to disconnect power before
changing a jumper can result in damage to the controller and void any warranties.
The controller cover is held in place by four plastic latches that extend from the base and snap into
slots on the inside of the housing cover.
To remove the controller cover, complete the following steps:
1. Place your fingertips under the two cover lift tabs on the sides of the housing cover and gently
pry the top of the cover away from the base to release the cover from the two upper latches.
2. Pivot the top of the cover further to release it from the lower two latches.
3. Replace the cover by placing it squarely over the base, and then gently and evenly push the
cover on to the latches until they snap into the latched position.
