Power Connection
The graphic below shows the power connections for the CH01M-AD, with one DC and one AC
power supply. When two supplies are connected, they are redundant, and the installed card device will
continue operation if only one supply is active.
The DC input utilizes a screw terminal block. Follow the proper polarity for DC, attaching the
negative DC voltage lead to the "-V" terminal and the positive DC voltage lead to the "+V" terminal.
Connect an Earth ground lead to the terminal marked "FG" (frame ground). DC voltage range input is
from 18 to 75VDC.
For AC power input, just firmly seat the IEC type power plug into the jack. The AC voltage range is
100-/- 10%. As long as the AC source is grounded, the ground will connect to the CH01/xx
chassis from the IEC connector.
Each power supply has a respective toggle switch which then sends the input power to the internal
supplies. The switch is OFF when set to "0" (zero) and is ON when switched to "1" (one).
