PNOZ X7

Installation

The unit should be installed in a control cabinet with a protection type of at least IP54.
}
Use the notch on the rear of the unit to attach it to a DIN rail (35 mm).
}
When installed vertically: Secure the unit by using a fixing element (e.g. retaining
}
bracket or end angle).
