2.3.2a Wiring: (cont.)
WARNING! Make sure that the +24 VDC wire (red) is connected to terminal TB1-1. Conn24 VDC to
any other terminal could cause bodily harm. It could also cause damage to the XMO2 PCB
requiring factory repair.
6. Tighten the side screws, and carefully plug terminal block TB1/TB2 back onto the XMO2 PCB.
7. Connect the other end of the cable in a similar manner to the TMO2D. Refer to Figure 11 on page 17 for the TB1
location.
