MEASUREMENTS AND INSTALLATION
For the dimensions and drilling template, see Figure 2 and Figure 3. Fit the controller to a panel
with the snap-in brackets supplied.
INSTALLATION PRECAUTIONS
-
Ensure that the thickness of the panel is between 0.8 mm and 2.0 mm (1/32 and 1/16
in)
-
Ensure that the working conditions are within the limits stated in the
TECHNICAL
SPECIFICATIONS
section.
-
Do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or
shocks.
-
In compliance with safety regulations, install the device correctly to ensure adequate
protection from contact with electrical parts. Fix all protective parts in such a way so as
to need the aid of a tool to remove them.

ELECTRICAL CONNECTION
Important
-
Use cables of an adequate wire gauge for the current running through them.
-
To reduce any electromagnetic interference, connect the power cables as far away
as possible from the signal cables.
For the electrical connection diagram, see Figure 4.

PRECAUTIONS FOR ELECTRICAL CONNECTION
-
If you use an electrical or pneumatic screwdriver, adjust the torque to a maximum of
0.5
N•m
(4 in. lb).
-
If you move the device from a cold to a warm place, the humidity may cause
condensation to form inside. Wait an hour before you switch on the power.
-
Make sure that the supply voltage, electrical frequency, and power are within the set
limits. See
TECHNICAL SPECIFICATIONS
.
-
Disconnect the power supply before you do any type of maintenance.
-
Do not use the device as safety device.
-
For repairs and further information, contact the Penn sales network.
