*1: Outputs are in accord with the specification of SDV526.
*2:
SWD2D is supplied from external power supply and outputs voltage via SDV526.

ALM T
erminals on SWD2D
Each terminal group has a pair of ALM terminals for sending a contact signal when fuse is
broken. When any fuse (1A to 4A, 1B to 4B, L and N) of a terminal group is broken, the con-
tact of the ALM terminals becomes closed. When all the fuses of the terminal group are nor-
mal, the contact of the ALM terminals stays open.
When the external relays are connected, a surge absorber should be used for inhibiting the
noises.

READY Terminals on the SBD2D
When statuses of power supply and fuses are all normal, the output from READY terminals
will be energized, i.e., the contact becomes closed. When power supply fails or any of the
fuses fails, the output from READY terminals will be de-energized, i.e., the contact becomes
opened.
If an external relay is used, a surge absorber should be used for noise prevention.
l
LED Status
When the power supply is normal, the LED is on. Otherwise, the LED is off.
