b.2.2 Power Input
Make sure the POWER switch on the back of the SDPROC is OFF. On one end of the AC
line cord is a universal connector that will fit securely into the AC inlet receptacle at the
rear of the SDPROC. Make this connection. Per your specifications at the time of your
order, on the opposite end of the AC line cord is a plug compatible with the AC power
receptacle you intend to use for AC power supply. Make this connection to the AC
power supply receptacle. The SDPROC is capable of receiving 85VAC to 240VAC and
50/60Hz power without any need for jumpering or compensation.
ƽ Use only the AC power line cord supplied with the instrument. Do not attempt to
force or manipulate the plugs of the AC line cord in any way. If it does not fit
easily and securely, contact your distributor or Aalborg
7.

INSTRUCTIONS section of this manual for details on controls and displays.
