ASD-120 SEQUENCED POWER DISTRO

normally closed or normally open contacts between each of the A to F terminals
and RELAY COM. The factory default is that the contacts are open when the asso-
ciated outlet is off (normally open).
The relay contacts may be easily converted to normally closed operation by
moving six “suitcase” jumpers on the ASD-120’s circuit board. To do this, first dis-
connect the unit from AC power. Remove the four screws that secure the top cover.
There are twelve small two-pin connectors labeled J1 through J12, located near
the left side of the largest circuit board. Six of the twelve are joined by small black
suitcase jumpers. To change the mode, gently pull them up and reposition them in
accordance with Table 4 below. Replace the top cover and screws.
