Install the Counter Module Chapter 3
Use an RTB
(1)
or interface module (IFM) to connect wires to your module. To
use an RTB, follow the directions below to connect wires to the RTB. IFMs are
prewired prior to shipping. The counter module supports IFM catalog numbers
1492-IFM40F, 1492-IFM40DS24A-4, 1492-IFM40F-FS24A-4, and
1492-IFM40F-FSA-4.
RTB Types
Use one of these types of RTBs with your counter module:
• Cage clamp, catalog number 1756-TBCH
• Spring clamp, catalog number 1756-TBS6H
Each RTP comes with housing. Wire the RTB with a 3.2 mm (1/8 in.) maximum
screwdriver before installing it onto the module.
Cage Clamp
Follow these steps to wire a cage clamp.
1. Strip 9.5 mm (3/8 in.) maximum length of wire.
2. Insert the wire into the open terminal on the side.
3. Turn the screw clockwise to close the terminal on the wire.
The open section at the bottom of the RTB is called the strain relief area. The
wiring from the connections can be grouped with a plastic tie.
