SPECIFICATIONS
Since significant current may be drawn from this unit,
it is advisable to leave the
mA
terminals open. The
current
OVLD
LED will remain on if the
mA
termi-
nals are open, and this indicator may be disregarded.
The
OVLD
indicator will be off and will behave nor-
mally under normal operation.
