4. PRECAUTIONSFORUSE
1) Checking the supplyvoltage
*Use thePS Series within the ratedsupplyvoltage range.
The power rating ofthePS Series is90to 132/180 to250VAC, single-phase,
50/60 Hz.
'<The ratedvoltage is indicated onthe rating platebeside the power input
terminals onthe rearpanel.
*The supplyvoltage rating (100VAC range or200VAC range) issetinthe
factory. Ifyou want to change the factory-set rating, pleasecontact
your dealer orour distributor.
2) Connecting thepower cord
Use the power cordincluded inthe accessories. Screw it onto the power input
terminals, then be sure toputthe protection cover onto the terminalblock.
10
WARNING

3) Power cord
*The power cordsuppliedwith the PS6-60,6-120,10-35,10-70,20-18,20-36,
36-10,36-20, 60-6,or60-12hasa rating of125V,10A.Itmaybe
connectedwith a wall socket ofa commercial AC power line. Ifan available
wall socket isofa parallel 2-pintype, usethe adapterplugincluded in
the accessories.
*The power cordssuppliedwiththree models otherthan theten shown above
have a rating of125V,15A.IfthePS Series istobe used fora load
over the power cord rating, remove the 2-pinplug from the power cord, fit
the wire tips withcrimp terminals orthe like, thenconnect the terminals
to the power distribution board ofthe available commercial power line.
Remove the 2-pinplug,
thenfit the wires withterminal lugs.

4)Precautions for applicat ion in floating cond i t i on
If thePS Series power supply unit is used inthe floating condition, a high
potential difference maybe produced between the frame GNDand output
terminals. If they are short-circuited in such a condition, a measuring
instrument oran electric loadconnected tothePS Series maybe broken.
If you touch the frame GNDand output terminals simultaneously by mistake, you
maygetan electric shock. Usethe greatest care. If highpotent ial
difference is produced between the frame GNDand output terminals, itmay
remaincharged inthe noise reducing capacitor even after use.In such a case,
connect a resistor of500kQorso between the frame GNDandthe positive
id negative output terminals to discharge the capacitor. (The capacitor is
discharged fora second orsowhena 500kQ resistor is connected.)
5) Notesonthe output terminals
*The PS Series isa floating type power supply unit. If itsoutputshould be
grounded, connect any output terminal onthe rear panel tothe frame GND
terminal with theGND cable included inthe accessories.
*A maximum of20A is outputthrough the output terminals onthe front panel.
If output current exceeding 20A is required, be sure tousethe output
terminals onthe rear panel.
1)
Checking the controlterminals and switches
onthe rear panel and notes on them
*A part ofthe remote control terminals is connected with the positive
terminal (+S terminal). Power supply or resistor used for remote control
should be floated. For detaiIs, readthrough the operation instructions
given below.
12
CAUTION

*The switches onthe rear panel are used to select an remote control method
and to change over the voltage remote sensingfunction. They aresetas
shown below inthe factory:
Only switch 1 is
set ON.
2) Notesonthe instalI ation condi t ions
and load applicat ions
*The ratedoperation temperature ofthePS Series is between 0 and 50°C.
If itis used atan extremely high ambient temperature, a built-in thermal
protector circuit functions and turns thepower relay off.
*DonotusethePS Serieswith theair intake inthe front panel andfan port
in the rear panel blocked. Keepa clearance of30cmormore between either
port andan objectnext to it. Donot allow hotairto enterinto the
unit through theair intake inthe frontpanel.
*DonotusethePS Series ina placesubject to dust,corrosive gas,etc.
*The PS Sereis isa switching type power supply unit. Note that itmay
have bad influences upon highly sensitive measuring instrumentsplaced onor
beside itor connected with thesameACpower line that thePS Series is
connected with.
*The PS Series isa switching type power supply unit. Donotuseitinthe
places orfor applications shown below:
1. UseinanEMI measuring site ora shielded room
2. Useinan adjustment and inspection line of receivers, tuners, etc.
3. Usefor loadsaffected by switchingnoises or ripples intheAC line
13

3) Notes onpoweron procedure
*When approx. a second has passed since thePS Series is powered on, decimal
points are displayed onthe voltage and currentindicator LED's. In approx.
three seconds sincethen, all digits and segments of these LED's goon.
Then, theOUTPUT switch becomes functional in approx. a second. In principle,
the OUTPUT switch is inactive when the power is turned on.
(Approx. a second after power on)
Onlydecimal
points goon.
Voltage and currentindicator LED's goon.
OUTPUT switch is inactive.
*When thePS Series is powered on,theAC line voltage may drop temporarily,
since largerushcurrentflows through thePS Series. Thus, be careful to
use other measuring instruments onthe same AC power line that thePS Series
is connected with.
Approx. three seconds
(Initial condition)
14

4) Notes on poweroff procedure
When the power of the PS Series is turned off with thePOWER switch on it, the
ALARM LEDonthe front panel goes on, which does not mean a trouble or
abnormality ofthePS Series. Ifthe power is turned on againwith the
ALARM LED lighting, the ALARM LED keeps lighting and operation ofthePS
Series is disabled.Beforeturning onthe power again, be sure to confirm
that theALARM LED is off.
The ALARM LED goes on.
Beforeturning onthe power again,
besure to confirmthat theALARM LED is off.
