Using the AC Adapter
The AC adapter can be used to provide power to the
indicator if battery power is low and AC power is
available. Use only the adapter supplied with the
indicator.
To use the AC adapter, do the following:
1. Remove the top screw from the AC adapter
port cover.
2. Loosen the bottom screw, then rotate the port
cover to expose the AC adapter port (see
Figure 2).
3. Reinstall the top screw in the backplate.
4. Plug AC adapter from power outlet to the
indicator adapter port.
The IQ plus 590-DC enclosure cannot
be rated for NEMA 4X/IP66 applications
with the AC adapter port cover open.
Do not use the AC adapter in washdown environments.
Figure 2. AC Adapter Port Cover
When not using the AC adapter, close the adapter port
cover and reinstall all backplate screws. Use the
torque pattern shown in Figure 3 to prevent distorting
the backplate gasket. Torque screws to 15 in-lb (1.7
