Why use an RI2 relay box?
If several LT or LS motors are operated using the same switch, you must always use a relay
box. If relay boxes are not used, the integral limit switches will soon burn out due to the
high inductive and capacitive voltages which are mutually generated.
A useful tip:
Always use the relay boxes and switches supplied by us for single operation
of 2 or more motors. The same applies to an automatic wind/sun screen.
