Installation
AC Power Considerations
The 8033 can be configured to operate at nominal line voltages of 100, 120, 220, or 240 VAC.
Normally, this configuration is done at the factory and need not be changed before operating the
instrument. Check to be sure that the voltage printed on the back panel of the instrument matches
the power−line voltage in your area. Refer to Chapter 5, Maintenance, if it is necessary to reconfigure
the input AC voltage range.
To avoid electrical shock hazard, connect the instrument to a properly earth grounded,
three prong receptacle only. Failure to observe this precaution can result in severe
injury or death.
Tilt-Foot Adjustment
The MPS−8033 has front legs that extend to make it easier to view the display. Place the 8033 on a
stable base and rotate the legs downward until they lock into position.
Rack Mounting
The MPS−8033 may be rack mounted by installing a rack mount flange on each side of the
enclosure. The rack mount accessory kits contain detailed mounting instructions. Refer to Table 1.2
on page 3 for applicable rack mount accessory part numbers.
Power-Up Sequence
Connect the MPS−8033 to an AC power source. Turn the KEYLOCK switch clockwise to the ON
position to supply power to the instrument and start the power up sequence.
The power−up sequence takes about six seconds. Initially, all LEDs illuminate and the seven−
segment display denotes "8888". Then, all LEDs and the display are extinguished while the
microprocessor executes a device self−test. If the self test fails, error message E720 is displayed.
Refer to Appendix A for an explanation of error messages.
