procedures for the power supply.
CAUTION
Always ground the equipment. Failure to connect the grounding cable to the
CSD-709 may result in electric shock or equipment malfunction.
The power supply input for the AC power type equipment features voltage of 100 V
to 240 V and frequency of 50/60 Hz.
The power consumption is about 10 W (at 100 VAC)
The tightening torque of the set screw on the connector board is as follows.
