Wiring Connections
Before performing any wiring or connection operations, ensure that controller power is OFF. Serious
damage to sensitive components on the controller may occur if wiring changes are made while
controller power is on.
Figure 4 – The SB-293 Satellite Board
The following instructions assume that TB-10 is pointed up. With one exception (the general-purpose
relay outputs), all connections to the SB-293 satellite board are made on the left side of the unit (see
Figure 4). Specific information for making each wiring connection is provided in the Terminal Block
Connections section listed below.
Terminal Block Connections
Follow these instructions as you make your wiring connections. Select the wire to be installed. Strip
away 1/4 inch of insulation from the wire, place the wire into the appropriate slot on the terminal
block, and tighten the corresponding screw on the top of the terminal block (see Figure 5 on page
16). Make a firm connection, but be careful not to over tighten the screw.
Please note that all of the terminal blocks slide off the SB-293 Satellite Board should it become
necessary to disconnect any installed cables. Firmly grasp the connector and pull it away from the
controller's printed circuit board (see Figure 5 on page 16).
