Normal Operating Conditions
Supply voltage
AC power supply : 90 to 250 VAC
DC power supply : 10 to 32 VDC (only for the subunit (DS400/DS600) of a DC power supply
model)
Supply frequency
50Hz
±2%, 60Hz ±2%
Ambient temperature
Main unit : 0 to 50 °C
DS400/DS600 Subunit :
when floor-mounted : 0 to 50

Shock
Not allowed
Magnetic field
400 A/m max. (50/60Hz)
Position
Unit should be positioned left-right horizontally
Installation location
Room
Installation height
Altitude up to 2,000 m
Installation category based on IEC 1010-1
II* 1
Pollution degree based on IEC 1010-1
2* 2
Warm-up time
At least 30 minutes after power switch-on.
*1 Installation category is the specification of the inpuls withstanding voltage which is also called as
overvoltage category.
*2 Polution degree is the level of foreign body adhesion such as the solid, liquid, and gas which decrease
the wuthstanding voltage, 2 means general indoor atmosphere.
