16 Installing the XM-720 Machine Monitor
3 4-20mA operation requires a jumper at terminals 25 & 26 (or terminals 28 & 29) if 4-20mA output is not used.
Otherwise the associated meter on front panel will not function properly. Refer to Connecting the 4-20mA
Outputs on page 29 for more information.
Connecting the Power Supply
The XM-720 monitor accepts inputs from 100-240V ac (47 to 63 Hz). The
internal power supply has internal (not accessible) input fuse. No other
protection is required. In order to meet local requirements, please consult local
codes and regulations for proper installation. Maximum rating of an
overcurrent protective device shall not exceed 15A.
Wire the AC power connections to the back panel as shown in Figure 2.4.

Connecting the Relays
The XM-720 monitor has both Normally Open (NO) and Normally Closed
(NC) relay contacts. Normally Open relay contacts close when the control
output is energized. Normally Closed relay contacts open when the control
output is energized.
The alarms associated with the relay and whether the relay is normally
de-energized (non-failsafe) or normally energized (failsafe) depends on the
configuration of the monitor.
