2.2 Power Connections
AC Power Connections
Instructions
1. Jumper selectable for 90 to 132
OR
180 to
264 VAC operation. Confirm AC power configuration
before applying power. See section 4.2 pg# 19
2. *A direct or low impedance AC ground (earth
ground) MUST be used for proper operation.
3. To reduce the possibility of noise interference, AC
power lines must be isolated from signal lines.
DC Power Connections
Note: AC/DC power can be connected simultaneously,
using DC power as an uninterrupted power source.
*A direct or low impedance earth ground MUST be used
for optimum performance.
