facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the ASR-002.
Avoid severe impact or rough handling that
leads to damaging the ASR-002.
Do not discharge static electricity to the ASR-
002.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the ASR-002 unless you are
qualified.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
AC Input voltage range:
230 Vac ± 15%
Frequency: 50/60 Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Disconnect permanently connected power input
before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.

GETTING STARTED
This chapter describes the ASR-002 power
controller in a nutshell, including its main
features and front/rear panel introduction.
ASR-002 Overview
ASR-002, which is a three-phase power controller, is able to controll
up to 3 single phase power supply units (ASR series only).
It effectively makes AC output conformed to 1P3W/3P4W that
generally unit requires, and also turns output into 3P3W via
designated wire method.
When the select single phase power is greater than the capacity of
2kVA, it is suggested that output should be connected to external
terminal for safety consideration.
