Chapter 2 Install the CompactLogix 5370 L1 Controller
3. If you are not using local expansion modules, use the tongue-and-groove
slots on the right side of the controller to slide a protective covering onto
the controller. The protective cover ships with the controller.
The covering covers the exposed interconnections on the right side of
the controller. Failure to use a protective covering can result in
equipment damage or injury from electric shock.
If you are using local expansion modules, see Local Expansion Modules
on page 157 for more information on how to install them in a
CompactLogix 5370 L1 control system.
Install the Removable Terminal Block
A removable terminal block (RTB) is supplied with your wiring base assembly.
To remove, pull up on the RTB handle. This feature allows the mounting base
to be removed and replaced as necessary without removing any wires. To
reinsert the removable terminal block, proceed as follows:
1. Insert the end opposite the handle into the base unit. This end has a
curved section that engages with the wiring base.
2. Rotate the RTB into the wiring base until it locks itself in place.
