Power Supply Voltage Setting; Fig.6 Driver Circuit Box Position; Fig.7 Driver Circuit Box Interior - Ulvac MBS-053 Instruction Manual

Note
If the pump is operated whilst it is tilted, placed on its side or upside-down, the
pump will be damaged. Install the pump level with the inlet facing up as shown
in Fig. 1.

4.3 Power supply voltage setting

Power supply can operate with 1φAC100 toAC120V (50/60Hz), 1φ AC200 to
240V (50/60Hz), but it is necessary to modify setting of motor power supply
(motor driver) in 100V system and 200V system.

(1). Take off a power cable of a driver circuit box of Fig.6
(2). Remove cover of a driver circuit box 10 seconds later.
(3). Replace the electric voltage change connector which showed in Fig.7.
The connector of a red wire 100V system and connector of blue wire 200V
system.
(4). Install cover of a box certainly, and insert a power cable.
Warning
Power circuit is damaged when I apply voltage more than 150V by connector
setting of 100-120V. In addition, there might be the ignition.
Caution
Start an operation in a driver box after passing more than 10 seconds after pull
out the power cable. Because electricity is stored to capacitors in the box, it is
feared that you get an electric shock. Power supply circuit is damaged when
you install wrong power supply voltage selection connector and in addition of
ignition might. At the time of shipping, set electric voltage by request in an
order however confirm setting just to make sure.
