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 power supply before connecting the device;

connect according to explanation in the “4 - Electrical connections” section
on page 25;

in compliance with the 2014/30/EU norm on electromagnetic
compatibility, following precautions must be taken:
- before handling and installing, 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 shield and/or the connector housing
and/or the frame 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. Provide the ground connection as close as possible to the
encoder. We suggest using the ground point provided in the cap, use one
TCEI M3 x 6 cylindrical head screw with two tooth lock washers.
