Safety Summary
The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these
precautions or specific WARNINGS given elsewhere in this manual will violate
safety standards of design, manufacture, and intended use of the instrument.
Chroma assumes no liability for the customer’s failure to comply with these
requirements.
BEFORE APPLYING POWER
Verify that the power is set to match the rated input of this
power supply.
PROTECTIVE GROUNDING
Make sure to connect the protective grounding to prevent an
electric shock before turning on the power.
NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding
wire, or disconnect the wiring of protective grounding terminal.
Doing so will cause a potential shock hazard that may bring
injury to a person.
FUSES
Only fuses with the required rated current, voltage, and

Programmable AC Source 61601/61602/61603/61604 Quick Start Guide
1. Introduction
The series of Chroma AC source 61601/61602/61603/61604 are high
efficiency AC source which provide sine wave output with low distortion,
and accurate measurement of power. The DSP microprocessor
generates accurate, stable output voltage and frequency. The PWM
design of power stage allows for full volt-ampere into loads. The front
panel has both RPG (rotary pulse generator) and keypad controls for
setting the output voltage and frequency. The LCD provides a complete
operating state of the unit to the user. Remote programming is
accomplished either through the GPIB bus or the RS-232C serial port.

2. Installation
2.1 Inspection
After unpacking the instrument, please inspect any damage that may have
occurred during the shipment. Save all packing materials in case the
instrument has to be returned one day. If any damage is found, please file
a claim with the carrier immediately. Do not return the instrument to the
factory without obtaining the prior RMA acceptance from Chroma.
2.2 Preparation for Use
In the beginning, the instrument must be connected with an appropriate AC
line input. Then, since it is intelligently cooled by fans, it must be installed
in sufficient space for circulation of air. It should be used in an area where
the ambient temperature does not exceed 40°C.
2.3 Requirements of Input Power
2.3.1 Ratings
Input Voltage Range : 90 ~ 250 Vac, single phase
Input Frequency : 47-63 Hz
Max. Current : 61601: 8 A
61602: 16 A
61603: 21 A
61604: 28 A
CAUTION The AC source will be damaged if it is operated at an
input voltage that is outside its configured input range.
2.3.2 Input Connection
The input terminal block is located on the rear panel of the instrument.
The power cord must be a three-conductor cord rated at least for 85°C.
The power line input must have a current rating which is greater than or 2-1

Programmable AC Source 61601/61602/61603/61604 Quick Start Guide
equal to the maximum current rating of the AC source. Do not use three
separate wires to connect power to the input of the AC source. Do the
following things one by one:
1. Remove the safety cover from the back of the AC source.
2. Screw the power cord to the terminal blocks of the AC source as
follows:
Green or green/yellow wire to the terminal labeled “G”.
White or blue wire to the terminal labeled “N”.
Black or brown wire to the terminal labeled “L”.
3. Slip the safety cover over the ac input terminal strip, and secure the
cover with two screws.
WARNING To protect the operators, the wire connected to the GND
terminal must be connected to the earth ground.
Under no circumstances shall this AC source be
operated without an adequate ground connection.
Installation of the power cord must be done by a professional and in
accordance with local electrical codes.
2.4 Power-on Procedure
WARNING Before turning on the instrument, all protective earth
terminals, extension cords, and devices connected to
the instrument must be connected to a protective earth
ground. Any interruption of the protective earth
grounding will cause a potential shock hazard that could
result in personal injury.
Apply the line power and turn on the power switch on the front panel. The
AC source will do a series of sel tests. The LCD on the front panel will
light up and display as below:
SELF TEST

Programmable AC Source 61601/61602/61603/61604 Quick Start Guide
Meanwhile, the AC source does the memory, data and communication self
test. After the routines of the self test are done, the display shows the
MODEL number, and the serial number of the AC source, and it shows an
“OK” at the right side of each test item indicating that the item is no problem.
It takes about six seconds to complete the routines of the self test. Then
the display shows the versions of software as below.

If any failure is detected on a certain item, an “ERROR CODE” will be
shown at the right side of that item. The error messages and
trouble-shooting are shown on 6.2 in Programmable AC Source 61601/
61602/61603/61604 User’s Manual. The test item "3. REMOTE "shows"
<EMPTY>, if the option board (with GPIB and RS-232) is not connected.
After finishing memory, data and communication self-test, the AC source
do the power output self test. In this procedure, the output relays are in
OFF status to sure not harming the load connecting on output terminal.
The AC source will program 300Vac and measure the voltage. If the
measured voltage is over 300V±5V, the power self-test is failed, and the
display will show "NG". If it's ok, the display is shown as below. Then, it
changes to MAIN PAGE automatically.

CAUTION 1. The user can do diagnosis if error or NG happened
in power-on self-test procedure. Please see 6.2
in Programmable AC Source 61601/61602/61603/
61604 User’s Manual.
2. The inner digital circuit of AC source maybe not
reset if turn off power then turn on immediately.
