Do not connect power cable to output terminals of the controller. Failure to comply could
cause controller damage and a fire.
4.2.2.4 Ground Terminal
Use grounding cables of dimensions regulated by electrical equipment standard. Shrink wiring
distance to prevent leakage current resulting unstable electrical potential at the terminal
distant from grounding terminal.
Do not use share the same grounding cable with welding machines or any controller requiring
large current. Failure to comply could cause controller or equipment malfunction.
Do not wind the grounding cable when multiple controllers are installed. Failure to comply
could cause controller or equipment malfunction.
Ensure the neutral of the input side and controller terminal "
to the local electrician regulations. TN and TT system are suggested for the controller primary
side.
4.2.2.5 Jumper
This controller complies with the European LVD standard EN 61800-5-1 (2007) reducing the
current leakage to below 10mA DC under testing condition regulated by IEC 60990 (1999).
Follow the instructions below to remove the jumper if an even lower current leakage to a even
lower level.
Removing the jumper may increase the signal interference.
