Precautions ConcerningInstallation

iv PAT- T 8kW
The PAT is a low-noise, highly efficient Constant Voltage (CV)/
Constant Current (CC) automatic crossover power supply that
employs a software switching system.
Capable to expand the system up to a maximum output of 40
kWby the master-slave parallel operation.
Communication functions for remote control also come
standard with the product.
The all models can also receive three-phase 200 Vac and
inputthree-phase 400 Vac input. In this manual, the three-
phase 400 Vac input models are often simply referred to as
“400 V input model.”
• Reduction of harmonic current and power transmission
loss
The power-factor improvement circuit reduces the effects of
harmonic currents on the input power line. It also
suppresses the peak current and reduces the power
transmission loss.
• Master-Slave parallel operation
Up to five power supplies can be connected in parallel to
expand the output power to 40 kW.
(Youcan expand the output power to 16 kWby connecting
two PAT850-9.4T power supplies in parallel.)
• Output limit function
Yo ucan set the upper limit of current and voltage that is
applied when setting the output.
This function is used to prevent setting inappropriate value
by mistake.
• Remote interface
Equipped with RS232C as standard. Youcan select the
GPIB, USB or LAN interface as a factory option.
The remote interface complies with IEEE 488.2 std 1992
and SCPI Specification 1999.0. Because the LAN interface
complies with the LXI standard, the construction of a highly
cost-effective system is possible.
•High efficiency and low noise
The PAT is a highly efficient, low-noise power supply that
employs a software switching system.
High power conversion efficiency has reduced the rise in the
internal temperature and has contributed to the product’s
compact and light design.
• Downsized input distribution device
The input distribution device (breaker) can be downsized,
because the built-in power-factor improvement circuit
reduces the required input current.
• Preset memory function of settings
Up to three output setting presets (combination of current
and voltage) can be saved.
Yo ucan simply select a preset to set the output without
having to set the voltage and current every time youuse the
PAT.
• Output on/off delay function
Yo ucan set a delay until the output is actually turned on or
off after turning the OUTPUT switch on or off.
For example, this feature is useful if youwant to turn the
output on/off by setting a time offset according to the load
characteristics.

1.3 Connectingthe Power Cable
This product is designed as an equipment of IEC Overvoltage Category II (energy-
consuming equipment supplied from the fixed installation).
p. 1-4 This product does not come with a power cable. The optional power cable (AC8-
4P4M-M6C) has crimping terminals (round M6 terminals, 12 mm wide) attached on
its PAT end. However, the switchboard end of the power cable has not been prepared
for connection. When you use the cable, attach crimping terminals to it that match
the screws of the switchboard that you will connect it to.
Fig.1-3 Optional power cable
Exercise the following precautions when preparing the power cable.
Possible electric shock.
• Turn off the switchboard breaker (switch that cuts off the power
supply from the switchboard) before makingthe connection.
• This product is an IEC Safety Class I equipment (equipment with a
protective conductor terminal). Be sure to ground the product to
prevent electric shock.
• Connect the ground terminal to earth ground.
• Be sure to have a qualified engineer connect the power cable to the
switchboard.
• Inside the power supply, an appropriate protective circuit is connected to
the input terminal. Be sure to connect the wires correctly by matching the
U, V, W, and (GND) between the switchboard and the product.
• The POWER switch of the product can be used to disconnect the product from
the AC line in an emergency. Provide adequate space around the POWER switch
so that the POWER switch can be turned off at any time.
Use a four-core PVC insulated cable for 600 Vac with a nominal cross-sectional
area of at least 8 mm2(At least 5 mm2for 400 V input model.)

Installation and Preparation
Connection procedure
Fig.1-4 Connecting the power cable
(example in which the optional power cable is used)
1 Check that the AC power line meets the nominal input rating of the
product.
A model with a nominal input rating of 200 Vac to 240 Vac can receive voltages within
the range of 180 Vac to 250 Vac. 400 V input models (whose nominal input rating is
400 Vac) can receive voltages within the range of 360 Vac to 440 Vac. The frequency is
50 Hz or 60 Hz.
Fig.1-5 Required power supply equipment
The PAT may be damaged.
• Do not connect a 400 V input model to a power line if the voltage between
any of the line’s phase terminals and the ground shown in Fig.1-5
exceeds 254 Vac.
2 Check that the POWER switch is turned off.
3 Attach crimping terminals to the cable that are appropriate for the PAT,
and then connect the cable to the AC INPUT terminal block as shown in
Fig.1-4.

switchboard.
Precautions ConcerningGrounding(Earth)
Be sure to ground the product for your safety.
Make sure to connect the GND terminal of the AC INPUT terminal block to the
GND terminal of the switchboard.
1.4 TurningOn
• The CONFIG parameters can be configured so that the output is
automatically turned on when the POWER switch is turned on. When this
function is enabled, the PAT powers up with the output turned on even if
the output was off when the PAT was turned off the last time. However,
there is a possibility that a load may break, if youconnect a different load
and turn the POWER and output on simultaneously without changing the
OVP and OCP settings to appropriate values.
Turningthe POWER switch on
1 Check that the power cable is correctly connected.
2 Raise the lever and turn the POWER switch on.
If an odd sound, odd odor, fire, or smoke occurs around or in the PAT, lower the
POWER lever to turn it off.
3 Check the firmware version on the front panel display.
p. 3-2
The voltmeter and ammeter show the PAT firmware version for approximately 1
second. The measuring value will be shown after the firmware version is displayed.

p. 3-28If the POWER switch is turned on for the first time after purchasing the PAT, the
PAT starts up in a factory default condition.
An inrush current flows up to 100 Amax. (40 Amax. for 400 V input model) when
the POWER switch is turned on. In particular, check that sufficient current capacity

is available in the AC power line and the switchboard if you are using multiple PATs
and turning on the POWER switches simultaneously.
If front panel display shows indicated in Table 1-1 after power-on, follow the
corresponding remedy. If the remedy does not correct the problem, contact your
Kikusui agent or distributor.
Table 1-1 Panel display during and after power-on
Turningthe POWER switch off
Lower the POWER switch lever to turn it off.
When the POWER switch is turned off, the front panel display shows the characters
indicated in the following figure for about 10 to 15 seconds.
Fig.1-7 Display at power-off
The PAT stores the panel settings (excluding output on/off condition) immediately
before the POWER switch is turned off. For these items, the PAT starts up using the
settings that existed when the POWER switch was turned off the last time.
If the POWER switch is turned off immediately after changing the settings, the last
settings may not be stored.
•When turning the POWER switch off and then back on, allowat least 10
seconds (40 seconds for 400 V input model) after the fan stops.
Repeated ON/OFF of the POWER switch at short intervals can cause
damage to the inrush current limiter or shorten the service life of the
POWER switch and the internal input fuse.
Panel Display Cause and Remedy
SYS1 ERR The PAT may have malfunctioned. Contact your
Kikusui agent.
SYS2 ERR
The calibration has not been completed normally.
Recalibrate. If “SYS2 ERR” appears even after
recalibration, the PAT may have malfunctioned.
