3. INSTRUCTIONS ON USE

3-1. Checking Source Voltage

・

Use the PAR-A series power supply units in the rated source voltage range.

・

The rated source voltage of the PAR-A series power supply unit is AC100V, 115V, 120V, 200V,

220V or 230V (voltage fluctuation:

10%), single-phase, 50Hz or 60 Hz.

・

The rated source voltage of the PAR-A series power supply unit may be selected with two

switches on the bottom plate. Be sure to check the source voltage before using the unit. See

section "5-3. Changing Source Voltage" for the method of changing the source voltage setting.

3-2. Connecting AC Cable

・

Use an AC power cable suitable to the input voltage rating of the PAR-A unit. Make sure that the

power switch is switched off, and connect the power cable to the AC power inlet securely.

3-3. Precautions for Connecting Output Terminals

・

The PAR-A series is a multi-channel power supply unit, which outputs positive and negative

voltages. Do not short the output terminals of the units sharing the same COM. Otherwise, a

trouble occurs.

・

The PAR-A series is a floating type power supply unit. When it is used in the floating condition,

high potential difference may be produced between the frame GND and output terminals (and

COM terminal). If the frame GND and output terminals (or COM terminal) are shorted in this

condition, the PAR-A unit and/or instruments connected with it may be damaged. Normally,

short-circuit the GND (frame GND) and COM terminal with the shorting bar supplied with the

product. Make sure that the MAIN OUTPUT key switch is set to OFF before connecting or

removing the shorting bar between/from the COM or GND terminal.

3-4. Installation Environments

・

The allowable ambient temperature range of the PAR-A series power supply unit is from 0

℃

. Do not use the unit at a temperature over or below this range. If the unit is used in a hot

place and the internal temperature rises, the built-in overheat protection circuit works and turns

off the MAIN OUTPUT key. Do not use the unit in the condition where the vents in the top panel

and air outlet port in the rear panel are blocked. Blocking these ports will also raise the internal

temperature. Keep sufficient distances between these ports and objects. In some conditions,

hot air blows out of the air outlet port in the rear panel. Be careful.

・

Do not use the PAR-A power supply unit in a place with much dust or corrosive gas.

Such substance may enhance deterioration of the product.
