Powering Up/Powering Down the Device
Do not attempt to connect power or disconnect power from the unit in a hazardous
area. Ensure the area is non-hazardous. Failure to do so could result in an explosion.
1. Remove the front end cap.
2. Terminal block TB1 includes connections for DC power (+DCIN, -DCIN) and
battery/solar power (+SPIN, -SPIN). Battery power (which is also used with solar
power) has its own internal connection.
Plug in TB1 to activate DC or solar power. If your device uses an internal
battery and it is not connected, connect it as discussed in Connecting the
Main Battery Pack.
Unplug TB1 to deactivate DC or solar power. If your device uses an internal
battery, disconnect the main battery.
3. Replace the front end cap. Screw it clockwise (eight full turns) until it is tightly
sealed to the enclosure.
This turns on (or turns off) power from an external power supply or from the battery
pack/solar panel.
Note
When you turn power on, the backlight on the HMI module lights, momentarily turns
off and then remains lit while the INPUT LED blinks. After approximately one minute
the initialization process completes and the HMI starts to display live data.
