Power Cord and Power Connection
The Reference 3000 does not plug directly in the AC mains supply. Instead, the mains are connected to an
external power supply, which supplies a regulated 24-V DC output. This regulated DC is then connected to the
DC
Power In
jack on the rear of the Reference 3000 (see Figure 4-2).
The external power supply provided with the Reference 3000 is rated for operation from 100 to 240 V AC, at
frequencies from 47 to 63 Hz. It should be usable worldwide.
The Reference 3000 external power supply is delivered with a line cord suitable for use in the United States. In
other countries, you may have to replace the line cord with one suitable for your type of electrical outlet. You
must always use a line cord with a CEE 22 Standard V female connector on the apparatus end of the cable.
This is the same connector used on the US standard line cord supplied with your Reference 3000. See
Chapter 1 for specific safety information regarding line cord selection.
Caution:
If your facility owns both Reference 600’s and Reference 3000’s, you must
insure that the smaller power adapter from the Reference 600 is
not
used to power a Reference 3000. The
Reference 3000 will not power up with the smaller adapter. Fortunately, neither the Reference 3000 nor
the small power adapter will be damaged if connected in error.
