2.1 Installing the OP37/Pro
The OP37/Pro is suitable for installation in
 19” (48,26 cm) cabinets/racks,
 front panels of control cabinets and desks.
!Caution
 In order to prevent the operator panel overheating,
– the unit must not be exposed to direct sunlight (this also prevents the
keyboard sealing film fading)
– the vent slots on the unit casing must not be covered over when the unit
is in its installed position.
 When installing the OP37/Pro, take the following points into account:
– The temperature inside the OP rises when it is installed on a slant. The
angle of inclination must not exceed 25 ° (refer to Appendix A). If not
installing the unit vertically , reduce the maximum ambient temperature,
e.g. by means of additional heat removal facilities (fan).
– The operator panel must not be installed horizontally since the cooling
principle of the heat pipe would not work any more.
Note
The IP65 enclosure rating of the front panel is only guaranteed if
 the seal on the front panel of the OP is properly seated
 the OP is correctly installed using the screw clamps supplied.
If you want to change the labeling of the function keys, perform the steps prior
to installing the OP37/Pro as described in Section 2.3.
Plan suf ficient space so as to be able to open the OP37/Pro even when it is in -
stalled. For example, when you replace the back-lighting, it must be possible to
swing a plate (refer to Figure 6-3 on page 6-4) through 90  after opening the
OP.
The OP37/Pro has a depth of approximately 330 mm with swung-out plate, as
measured from the front panel.
Use the section bars of the cabinet or rack manufacturer concerned to mount
the OP37/Pro.
Mounting dimensions of the OP37/Pro for a standard 19” cabinet:
W idth: 19” (48.26 cm) height: 7 height modules
The OP/OP front panel is fixed to the frame sections by means of four screws.

To install the unit, proceed as follows:
1. Make a mounting cutout in the front panel having a size of
436-1.5 x 295
-1.5
(width x height in mm).
The front panel must not be thicker than 16 mm. You will find details of the
useful depth in the T
echnical Data contained in the appendix.
2. Insert the operator panel in the prepared cutout from the front. T ake suit -
able precautions to prevent the OP from falling out of the front panel until
it has been properly secured.
3. Securely attach the OP to the front panel using the six screw clamps

supplied. Figure 2-1 shows the positions for the screw clamps.

2.3 Labeling Function Keys
When the unit is supplied, the operator panel function keys are labeled as fol -
lows:
 F1 to F20 and
 K1 to K16.
A set of unlabeled strips is included with the OP . This means that you can pre -
pare labels for the OP specifically for your system.
T o replace the labeling strips proceed as follows:
1. Place the unit face down.
!Caution
Make sure the OP is disconnected from the power supply .
2. W ith reference to Figure 2-4, release the rivets

Note
The

Electrical Installation
The basis for trouble-free operation is electromagnetic-compatible PLC design
and the use of interference-free cables.
The guidelines for the interference-free installation of your PLC apply to the
electrical installation of your operator panel too.
!Caution
 All signal links must use shielded wiring only .
 All connectors must be secured by screws or catches.
 Signal lines must not share a common cable duct with high-power cables.
