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 on page 17 for the TB1
location.

CAUTION!
Do not make any connections to unassigned or unused terminals.
2.3.2.2 CE Mark Compliance
IMPORTANT: CE Mark compliance is required only for units used in EU countries.
For CE Mark compliance, you must use shielded cable and connect the shield to a cable gland (see Figure 3 on
page 7). After you make all the necessary electrical connections, seal the unused cable entry holes with standard
conduit plugs or their equivalent.
Note: If you make the modifications as discussed here, your unit will comply with the EMC Directive 2004/108/EC.
Note: For CE compliance, the I/O cables must be shielded. The shields are to be grounded within the TMO2D to the
closest location. Shielded cable is not required when installations include metal conduit.
