Connecting the measuring unit
Cable entry
• Cable gland: M20x1.5
• Cable entry: G ½ or ½ NPT
• PROFIBUS PA M12 plug
Supply voltage
The following values are the voltages across the terminals directly at the instrument:
Current consumption
approx 13 mA for the range of voltages given above
Overvoltage protector
The level transmitter Micropilot M with T12-housing (housing version "D", see ordering
information) is equipped with an internal overvoltage protector (600 V surge arrester) according to
DIN EN 60079-14 or IEC 60060-1 (impulse current test 8/20
μ
s, Î = 10 kA, 10 pulses). Connect
the metallic housing of the Micropilot M to the tank wall or screen directly with an electrically
conductive lead to ensure reliable potential matching.
Connection with M12 plug
The Micropilot M PROFIBUS PA sensor version with M12 plug is supplied ready wired and need
only be connected to the bus by means of a suitable cord set.
