l Atmospheric pressure: 86 to 106kPa
2.2 Mounting Process
（1）Cut out rectangle holes on the panel for installing the controller according to the required hole size.
When installing more than one controller, the minimum horizontal and vertical distance between two holes should be
25mm and 30mm respectively.
（3）Insert the controller into the hole on the panel.
（4）Insert mounting bracket in the slot for mounting the controller.
（5）Push the mounting bracket tightly to connect the instrument and the panel firmly.
