2.3.2 Removing and Installing Wire Channel Covers
Install the wire channel covers over the wiring channels once the wiring
of the terminal blocks is complete. Wire channel covers are located on
the front of the ROC800 housing.
To remove a wire channel cover:
1. Grasp the wire channel cover at both the top and bottom.
2. Start at the top or bottom and pull the wire channel cover out of the
wire channel.
To replace a wire channel cover:
1. Align the wire channel cover over the wire channel, allowing
unobstructed wire access.
2. Press the wire channel cover into place until it snaps.
Note: The tabs on the left side of the wire channel cover should rest in
the slots on the left edge of the channel.
2.3.3 Removing and Installing Module Covers
Before you insert an I/O or communications module, remove the
module cover over the empty module slots in which you intend to install
the modules. Although you are not required to remove the power to the
ROC800 to perform this procedure, caution is always advisable when
working with a powered ROC800.
To avoid circuit damage when working inside the unit, use appropriate
electrostatic discharge precautions (such as wearing a grounded wrist
strap).
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous state
before performing procedures. Performing these procedures in a
hazardous area could result in personal injury or property damage.
