SAFETY INSTRUCTIONS
This chapter contains important safety instructions that you must
follow during operation and storage. Read the following before
any operation to insure your safety and to keep the instrument in
the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the instrument.
WARNING
Warning: Identifies conditions or practices that could result in
injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that could result in
damage to the instrument or to other properties.
DANGER High Voltage
Attention Refer to the Manual
Earth (ground) Terminal

ISA-730 Instruction Manual/English
4 21/11/2016 Version No. 002
Frame or Chassis Terminal
Do not dispose electronic equipment as unsorted municipal
waste. Please use a separate collection facility or contact the
supplier from which this instrument was purchased.
Safety Guidelines
General Guideline
CAUTION
Do not place any heavy object on the instrument.
Avoid severe impact or rough handling that leads to
damaging the instrument.
Do not discharge static electricity to the instrument.
Use only mating connectors, not bare wires, for the
terminals.
Ensure signals to the RF input do not exceed +30dBm/
±25V DC.
Do not block the cooling fan opening.
Do not disassemble the instrument unless you are
qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows.
The instrument falls under category II.
Measurement category IV is for measurement performed at
the source of low-voltage installation.

SAFETY INSTRUCTIONS
21/11/2016 Version No. 002 5
Measurement category III is for measurement performed in
the building installation.
Measurement category II is for measurement performed on
the circuits directly connected to the low voltage
installation.
Measurement category I is for measurements performed
on circuits not directly connected to Mains.
Power Supply
WARNING
AC Input voltage range: 100V~240V
Frequency: 50/60Hz
To avoid electrical shock connect the protective grounding
conductor of the AC power cord to an earth ground.
Cleaning
Disconnect the power cord 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.
Operation
Environment
Location: Indoor, no direct sunlight, dust free, almost non-
conductive pollution (Note below)
Temperature: 5°C to 45°C
Humidity: 90% @ 45°C
(Pollution Degree) EN 61010-1:2010 specifies the pollution
degrees and their requirements as follows. The instrument

ISA-730 Instruction Manual/English
6 21/11/2016 Version No. 002
falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of
dielectric strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity
caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry,
non-conductive pollution occurs which becomes conductive
due to condensation which is expected. In such conditions,
equipment is normally protected against exposure to direct
sunlight, precipitation, and full wind pressure, but neither
temperature nor humidity is controlled.
Storage
environment
Location: Indoor
Temperature: -20°C to 60°C; <60°C/70% RH
Disposal
Do not dispose this instrument as unsorted municipal waste.
Please use a separate collection facility or contact the
supplier from which this instrument was purchased. Please
make sure discarded electrical waste is properly recycled to
reduce environmental impact.
Power cord for the United Kingdom

SAFETY INSTRUCTIONS
21/11/2016 Version No. 002 7
When using the unit in the United Kingdom, make sure the power cord meets the
following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with the coloured marking
identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal
marked with either the letter E, the earth symbol or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with
the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the
letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved HBC mains
fuse: refer to the rating information on the equipment and/or user instructions for details.
As a guide, a cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the connection method
used.
Any exposed wiring from a cable, plug or connection that is engaged in a live socket is
extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power
and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above standard.
