The Eaton Cutler-Hammer 92-01273-03 Operator Interface Terminal has a power voltage range of 18 to 30 Volts DC. This operator interface terminal is a video control panel for devices from the Eaton 1575 PM and 1500 Power series. It is recommendable to test this video control panel before installing it in the industrial enclosure it is intended for. There are 3 steps for testing the unit. The first is connecting the operator interface terminal to a DC power source by using a removable connector shipped with the PanelMate unit that operates at 24 Volts DC. The second step involves powering up the video control panel after connecting the DC power source's connector to it. The unit conducts a diagnostic analysis, and a list of the different checks are displayed as they are carried out in this step.

When the Eaton Cutler-Hammer 92-01273-03 PanelMate Terminal completes this testing process, it goes back to then state it was in when it was switched off. The third step of the testing process is to use the Offline Mode menu to carry out the system diagnostics. On the third and last step, the users need to choose the template called the "Execute Diagnostics" template and press the "Execute" button. A new screen with choices will pop up. On the screen, the users will be able to carry out tests, including keypad tests, display tests, and battery and tone tests. The users can also set the time and date on this screen. The Eaton Cutler-Hammer 92-01273-03 Terminal has an operating temperature between 0 and 50 degrees Celsius for grayscale display units and 0 to 40 degrees Celsius for color display units. It has a storage temperature between -20 to 60 degrees Celsius for both display types. The terminal has a relative humidity range from 20% to 80% non-condensing for grayscale units and from 20% to 90% non-condensing for color units.
