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 removing cover and

changing the position of any jumper or the EOL switch on the controller. Failure to disconnect

power before changing a jumper or EOL switch position 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:

1. Place your fingernails under the two cover lift tabs (Figure 3) 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.

Setting the End-of-Line (EOL) switch

About this task:

Each controller has an EOL switch, which, when set to ON, sets the controller as a terminating device on the

bus. See Figure 11 for the EOL switch location. The default EOL switch position is Off.
