*1 It is necessary to have the unit repaired if the load is short-circuited resulting in the fuse melting down. Note that the fuse
cannot be replaced by the user.
*2 It is necessary to supply 12/24 V DC to the S terminal externally.
*3 In case of an inductive load, a surge killer should be connected (0.1

F capac approx. 100
Ω
resistance) in parallel
with the load. Also, in case the load contains a DC voltage component, a flywheel diode should be connected as well.
*4 A built-in fuse is not used in this unit. Install a 6 A fuse at the common terminal in order to prevent the external wiring
from burning out.
