1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, snap-in brackets provided.
INSTALLATION PRECAUTIONS
- The thickness of the panel must be between 0.8 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, the device must be installed properly to ensure
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.
2 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.
- Power supply for TC3224N9R: 115... 230 VAC.
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 the device was moved from a cold to a warm place, the humidity may have caused
-
condensation to form inside. Wait about an hour before switching on the power.
Make sure that the supply voltage, electrical frequency and power are within the set
-
limits. See the section TECHNICAL SPECIFICATIONS.
Disconnect the power supply before doing any type of maintenance.
-
- Do not use the device as safety device.
For repairs and for further information, contact the PENN sales network.
