SAFETY SUMMARY
This power source contains high voltage and current circuits, which are potentially lethal.
Because of its size and weight, mechanical stability must be ensured. The following safety
guidelines must be followed when operating or servicing this equipment. These guidelines
are not a substitute for vigilance and common sense. California Instruments assumes no
liability for the customer’s failure to comply with these requirements. If the power source is
used in a manner not specified by California Instruments, the protection provided by the
equipment may be impaired.
BEFORE APPLYING POWER
1. Verify the correct three phase input voltage is applied to the unit. Input ratings are shown on the
model and serial number tag located at the rear of the unit.
2. The chassis and cabinet of this power source must be grounded to minimize shock hazard. A
chassis ground is provided at the input terminal block. This is located in the front of the cabinet
on the lower left hand side. The lower front cover panel must be removed to access the line
input and ground connections. The chassis ground must be connected to an electrical ground
through an insulated wire of sufficient gauge.
FUSES
Use only fuses of the specified current, voltage, and protection speed (slow blow, normal blow, fast
blow) rating. Do not short out the fuse holder or use a repaired fuse.
DO NOT OPERATE IN A VOLATILE ATMOSPHERE
Do not operate the power source in the presence of flammable gases or fumes.
DO NOT TOUCH ENERGIZED CIRCUITS
Disconnect the power cable before servicing this equipment. Even with the power cable
disconnected, high voltage can still exist on some circuits. Discharge these voltages before servicing.
Only qualified service personnel may remove covers, replace components or make adjustments.
DO NOT SERVICE ALONE
Do not remove covers, replace components, or make adjustments unless another person, who can
administer first aid, is present.
DO NOT EXCEED INPUT RATINGS
Do not exceed the rated input voltage or frequency. Additional hazards may be introduced because of
component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS
Do not modify this instrument or substitute any parts. Additional hazards may be introduced because
of component failure or improper operation.
MOVING THE POWER SOURCE
When moving the power source, observe the following:
1. Remove all AC power to unit.
2. Don not attempt to lift by hand. Raise the levelers and push the unit using two people to prevent
injury or use forklift equipment with a qualified operator.
ALLOW CAPACITORS TO DISCHARGE
Capacitors in the power source may hold a hazardous electrical charge even if the power source has
been disconnected from the mains supply. Allow capacitors to discharge to a safe voltage before
servicing internal circuits or touching exposed pins of mains supply connectors.

User Manual – Rev AJ California Instruments
1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of all power systems that use the MX Series power sources with the
programmable controller.
1.1 General Description
The MX Series AC and DC power source systems are high efficiency, floor standing AC and DC
power sources that provide a precise output with low distortion. Available voltage ranges are
150 Vac, 300 Vac and 400 Vac in AC mode and 200 Vdc and 400 Vdc in DC mode. The MX303Pi and MX45-3Pi can operate in either single or three-phase mode. The MX30 and MX45 is
also available in just single or three-phase mode. All other models always operate in threephase mode.
Models with a -1 or -3 designation provide full front panel operation but do not include certain
features such as arbitrary waveform generation unless added as an option at the time of order.
Models with the Pi controller offer several additional standard features, including the RS232C,
USB, LAN (option) and IEEE-488 interfaces, arbitrary waveform generation, dual voltage ranges
and additional measurement functions.
The MX Series units are contained in a compact floor standing enclosure on casters. This allows
the units to be moved around more easily.
Read the installation instructions carefully before attempting to install and operate the MX Series
power systems.
1.2 Manual organization and format
All user documentation for California Instruments power sources is provided on CDROM in
electronic format. (Adobe Portable Document Format) The required Adobe PDF viewer is
supplied on the same CDROM. This manual may be printed for personal use if a hardcopy is
desired. To request a hardcopy from California Instruments, contact customer service at
support@calinst.com. There will be an additional charge for printed manuals.
This manual contains sections on installation, normal use, maintenance and calibration. If the
MX system is equipped with a GPIB, RS232C, USB or LAN interface, refer to the MX
Programming manual for information on using the remote control interfaces and command
syntax. The programming manual is provided on the same CDROM as this user manual.

1.3 Different Model Series
There are two versions of the MX Series product, Series I and Series II. This user manual
covers both MX model series with top level assembly part numbers 7003-400 (Series I) and
7003-422 (Series II). The difference between the Series I and the Series II is the controller used.
The Series II uses a newer controller design but retains backward compatibility with the Series I
products. The part number is shown on the model / serial number tag on the back of the MX
series. All Series II will have a firmware revision of 4.0 or higher. The firmware revision is
displayed briefly at power up on the LCD display and can also be queried over the bus by using
the *IDN? command.
Differences between the two model series are restricted to:
Reduced number of measurement calibration coefficients on Series II.
Increased measurement sampling rate on Series II.
Maximum DC offset range in AC+DC mode is 250Vdc on Series I, 220Vdc on Series II
Where relevant, differences are highlighted throughout the user manual.

Misc. Options
-ES Emergency Shut off switch. This option key lock push button is installed
on the front panel of the master MX if ordered with the MX system. When
pushed in, the main AC contactor is opened disconnecting the AC input
power to the MX input transformer. Note that the controller (and LCD
display) will still be powered up but no power is available to the amplifiers
and there will be no output power either. The controller runs off the LV
supply, which must be turned off with the front panel breaker.
After the ES has been pushed, the provided key will be required to
release it. Once the ES button has been released, the MX must be
powered down using the front panel circuit breaker and turned back on to
start up again.
Note: For multibox MX Systems (MX90 and up with more than one
controller and front panel controls, each of which having an ES
emergency switch, to connect a BNC cable between the cabinets for the
ES connection. For 3 or more cabinets with controller, this BNC can be
daisy chained using BNC T connectors.
Note: Do not misplace the 2 keys provided, as no duplicates are
available from CI. If lost, the ES switch must be replaced. In that case,
contact California Instruments customer service. (
support@calinst.com ).
