1 Use a twisted two core shielded wire for the power wire.
2 Shows input resistance of Q68ADV.
3 "A.G." terminal does not normally require wiring. However, it can be used as GND
for compatible equipment ground under the followin g conditions.
(1) When there is a difference in polarit y between "A.G" and "GND for compatible
equipment".
(2) As an alternative for 0 V input when only the + side is open on a ± wire.
4 Always use a ground. In addition, ground the FB of the power supply module.
