1.1 Safety
•
Always adhere to the professional safety and accident prevention
regulations applicable to your country during device installation and
operation;
•
installation and maintenance operations have to be carried out by
qualified personnel only, with power supply disconnected and stationary
mechanical parts;
•
device must be used only for the purpose appropriate to its design: use for
purposes other than those for which it has been designed could result in
serious personal and/or the environment damage;
•
high current, voltage and moving mechanical parts can cause serious or
fatal injury;
•
warning ! Do not use in explosive or flammable areas;
•
failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture,
and intended use of the equipment;
•
Lika Electronic assumes no liability for the customer's failure to comply
with these requirements.
1.2 Electrical safety
•
Turn OFF the power supply before connecting the device;
•
connect the unit according to the explanation in the ”4 - Electrical
connections” section on page 14;
•
the wires of unused signals must be cut at different lengths and insulated
singularly;
•
in compliance with 2014/30/UE norm on electromagnetic
compatibility, following precautions must be taken:
- before handling and installing the equipment, discharge
electrical charge from your body and tools which may come in touch
with the device;
- power supply must be stabilized without noise; install EMC filters on
device power supply if needed;
- always use shielded cables (twisted pair cables whenever possible);
- avoid cables runs longer than necessary;
- avoid running the signal cable near high voltage power cables;
- mount the device as far as possible from any capacitive or inductive
noise source; shield the device from noise source if needed;
- to guarantee a correct working of the device, avoid using strong magnets
on or near by the unit;
- minimize noise by connecting the cable shield and/or the connector
housing and/or the sensor to ground. Make sure that ground is not
affected by noise. The connection point to ground can be situated both
on the device side and on user’s side. The best solution to minimize the
interference must be carried out by the user.
