The monitor must be located in the safe area of the application plant in a sheltered interior environment.
The monitor is intended to be panel mounted in a position to suit reading of the displays and with access to the rear to enable

monitor is secured to the panel by two clamping brackets at opposite corners of the monitor chassis.
