Description of Each Part
23
Each common needs to be in a floating condition at a withstand voltage of 1,500 VAC or more
above the earth and the portions between the common ports need to be insulated. If the power
supply equipment you use connects to the earth, use isolation amplifiers to insulate signals.
10) FIL
．
VOLT indicator
（
Red
）
This lights up to indicate that a voltage is applied to the filament.
11) MAIN circuit breaker
This is the main power switch of this power supply.
This trips if the panel of the power supply main unit is not normally closed.
12) EXT
．
START connector
This enables one to turn on/off the power supply and to turn off (trip) the MAIN circuit breaker by
external contacts.
For a self-holding type, make connections following Fig. 4.4. For a single contact type, you can turn
on/off by inserting a contact between Pin No. 1 and No. 3.
If you do not use this function, short-circuit between Pin No. 1 and No. 3.
Be sure to do the wiring of the EXT. START connector following Fig. 4.4. If the power supply is
turned on without wiring connectors, the fan of the power supply main unit rotates but the indicators
does not light up and the power supply does not work correctly.
