Power Supply NGMO

Operator Information

1-2

4.00 / 07-2004

1.2.1 NGMO1

The Power Supply NGMO1 consists of the following assemblies:

•

Keyboard with LC Display

•

Processor

board

•

Analog board for Channel A

•

Power supply unit

1.2.2 NGMO2

The NGMO2 is equipped with two analog boards and therefore delivers
two separate voltage sources and signal channels. Apart from that the
Power Supplies are absolutely identical.

1.3 Purpose of the Handbook

The operating manual contain all the information you will need to use
the Power Supply NGMO.

This manual describes

•

safe installation and assembly,

•

appropriate and safe operation,

of the Power Supply.

Read the operating instructions carefully before you use the Power
Supply. The operating instructions contain important information which
must be acted on.

Apart from the information in the operating instructions, the statutory
safety regulations that apply in the country of use, the relevant techni-
cal standards and the regulations concerning the safe and appropriate
use of electrical equipment must also be observed.

The operating instructions belong to the unit and must always be avai-
lable at the place of use of the Power Supply NGMO.

The owner must observe national safety and environmental protection
regulations.
