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 w h en 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 b y California In struments, 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. Do 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 the mains supply connectors.

User Manual – Rev B FCS Series II
1. Introduction
This instruction manual (P/N 5000-967) contains information on the installation, operation,
calibration and maintenance of the FCS Series II AC power sources.
FCS Series II models are different from the original FCS Series in the following areas:
• New higher performance controller with arbitrary waveform capability is used.
• Standard RS232 and USB interfaces have been added in addition to GPIB.
• Optional Ethernet LAN interface is available. (Option –LAN).
• The front panel keyboard display is more user friendly with full decimal keypad for data
entry.
• Number of available output voltage range options has been reduced to 135/270
(standard), 156/312 or 200/400.
1.1 General Description
The FCS Series II AC Power Source is a high efficiency, cabinet AC Power Source/Analyzer
combination that provides a precise output and advanced measurements. Standard output
voltage ranges are 135 Vac and 270 Vac RMS. The FCS II Series is available in either single (-
1) or three-phase (-3) mode. Three phase units offer an optional single-phase mode for both
modes of operation.
For power levels above 18 KVA, two or more FCS series units can be combined using the
system interface in a parallel mode of operation. These multi chassis systems consist of one
master unit with controller and one or two auxiliary units without controllers. Only the master unit
has a front panel keyboard and display.
Read the installation instructions carefully before attempting to install and operate the FCS
Series II power systems.

Inspect the unit for any possible shipping damage immediately upon receipt. If damage is
evident, notify the carrier. DO NOT return an instrument to the factory without prior approval.
Do not destroy the packing container until the unit has been inspected for damage in shipment.
If possible, retain the container in the event the system ever has to be returned to the factory for
either repair of upgrades.
A forklift should be used to remove the FCS cabinet from its shipping crate. Once on a level
floor, the cabinet can be pushed in place using it’s own casters. Levelers at each corner may be
used to prevent the unit from moving. Levelers are not intended to support the entire weight of

AC input connections are to be made directly to the input terminal block (TB1) of all units that
make up an FCS system. The input block is located on the lower right hand corner of the back
of the FCS18 chassis when facing the back. It is labeled “TB1” and “INPUT”. To connect AC
input wiring, remove the safety cover from the input junction box using a screwdriver to gain
access to the terminal block.
A Ground (earth) wire must be connected to the chassis of the AC power system using the
ground connection of the AC input connecter block. The mains source must have a current
