SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Important
Please follow the safety instructions in the PMX Operating Manual and in the separate
"Safety Instructions" document (enclosed with the device).
2 PURPOSE OF THE MANUAL
This Quick Start Guide sets out the key points when mounting a PMX device and connect
ing it to a PC, making it easy for you to start gathering measurement results with your
PMX.
It also provides a concrete example of setup with commonly used transducer types.
Important
This Quick Start Guide does not replace the detailed PMX Operating Manual.

Fig. 4.1 Mounting on a support rail
1. Loosen the four rear panel screws (Torx Tx10) (1).
2. Push the side panels forward (2).
3. Screw on the support rail mounting (3) (about 5Nm). Four positions (Ato D) are op
tionally possible (two positions for 7.5 mm rail).
4. Screw the side panels (2) back on.
5. Attach the PMX to the support rail (4).
Notice
Device damage by dropping the PMX due to difficulty of attaching/detaching the PMX.
HBM recommends using a DIN support rail (DIN EN 60715) with a height of 15 mm. When
using a smaller support rail (7.5 mm high), it should be packed, to make it easy to attach/
detach the PMX.
The 7.5 mm support rail can only be used in the top two positions (A and B).

To ensure sufficient grounding of the PMX, the support rail must be connected to func
tional ground .
Both the support rail and the PMX must be free of paint and dirt at the mounting location.
uConnect the PMX housing to ground via the grounding screw.

Fig. 4.6 PMX with cable holder
To ensure that cables running from and to the PMX are fastened securely and reliably, an
optional plate can be secured to the top and bottom of the PMX mainframe to fasten the
cables using two M4 hexagon socket screws for each plate.
Holes in the plate can be used to fasten the cables using cable ties.

5.1 Preparing the measurement system
5.1.1 Connecting transducers
All PMX plug-in cards (PX401, PX455, PX460, PX878) are supplied as standard with easy-
fit push-in plug terminals. But you can also obtain screw-type terminals from Phoenix
Contact (www.phoenixcontact.com
).
The clamping area is 0.2mm2(AWG24) to 1.5mm2(AWG16). If you need to connect
multiple wires to one terminal, adapt the wire cross-sections accordingly. Use 10mm
wire end ferrules (without plastic collars) to connect the wires to the terminals wherever
possible.
Notice
The plug terminals are not interchangeable ex factory. Depending on the sensor type, plug
connection errors can damage the plug-in card.
Use the supplied coding pins to prevent interchanging.
The plug terminals can be protected by coding pins against interchanging. To do this,
insert a coding pin fully into one of the slots in the device sockets and snap it off from the
holder - see Fig. 5.1. Use a different slot for each plug terminal and transducer type. You
can also use more than one coding pin for one plug terminal.
Fig. 5.1 Coding pin 90% inserted
Remove the lug on the corresponding plug terminal connector, using a knife for example
(Fig. 5.2).

Attach the shield of the transducer cable to the ground connection provided on the PMX's
multipoint connector, in accordance with HBM Greenline information https://www.hbm.
com/Greenline.
Important
The ground terminal on the PMX is not a protective ground (connection optional).
The measurement system features automatic current limitation for each device card and
for the PMX basic device.
Connect your transducers to the measurement cards (plug terminals).

The PMX boots, and then displays its system status. The system LED must light up green.
This process takes a few seconds.
5.1.3 Connecting to a PC
Connect the PMX to a PC via the Ethernet socket.
ÑÑ
Cable: Standard Ethernet cable (Cat5)
The PMX is set to DHCP (automatic address assignment) at the factory. Set your PC to
DHCP as well. The IP addresses will then be set automatically. This process takes sev
eral tens of seconds.
