Warning:
 To connect the inductive load (relay, electromagnetic contactors, motor ... etc.
）
, please
install RC network or Varistor beside the coil.
 Please install fuse (the spec can
’
t greater than contact limits) in the loops for safety
concern.
 Please use isolated cable to prevent the interface as far as possible.
 Please have soldering or terminal for cable.
 Based on the safety considerations, please keep more than 15cm with other control, motor
and power cables and wiring independently; please keep the vertical wiring if it is
necessary for cable staggering.
 All operations can NOT exceed the limitation of spec.
