the manual in order to protect against personal injury or damage the equipment.
GROUND Indicates protective Ground Terminal
CAUTION
The CAUTION symbol indicates a potential hazard. It calls attention to a procedure, practice or
condition which, if not followed, could possibly cause damage to equipment. Such damage may
invalidate the warranty. If a CAUTION is indicated, do not proceed until its conditions are fully
understood and met.
WARNING
The WARNING symbol indicates a potential hazard. It calls attention to a procedure, practice
or condition which, if not followed, could possibly cause bodily injured or death. If a WARNING
is indicated, do not proceed until its conditions are fully understood and met.
Power Supply
The equipment is intended to operate with a power supply not to exceed 250 volts between phase and neutral or between
phase and ground. A proper ground connection through the ground connector of the power cord is essential for safe
operation.
Grounding the Generators
The generators are grounded through the power cord. To avoid electric shock, plug the power cord into a properly installed
receptacle which was tested by a qualified electrician. Have the test performed before connecting equipment.
Without the protective ground connection, all parts of the generators are potential electric shock hazards. This may include
components which appear to be insulated. The equipment MUST NOT BE USED if this protection is altered.
Use the Proper Power Cord
Use only power cords and connector specified for your product. Use only power cords in good condition.
Use Proper Fuses
To avoid fire hazard, use only fuses as specified in the parts listing for your product - matching type, voltage and current
rating.
Do Not Remove Covers or Panels
To avoid personal injury, do not operate the generators without panels and covers.
Do Not Operate in an Explosive Environment
Electric Overload
Never apply power to a connector which is not specified for that particular voltage/current.

CAUTION
Before using this equipment, read the user manual and the
separate delivered safety manual carefully
1.3. Responsibility of the operator
These operating instructions form an essential part of the equipment and must be available to the operator at all times. The
user must obey all safety instructions and warnings.
CAUTION
The purpose of this instrument is the generation of defined interferences signals for EMI immunity
testing. Depending on the arrangement of the test rig, the configuration, the cabling and the properties
of the EUT itself, a significant amount of electromagnetic radiation may result that could also affect other
equipment and systems.
The equipment is designed to operate in industrial environment. For operating in other or sensitive
environment, such as light industry, airport area…, the user may use a shielded room for operate.
The user himself or herself is ultimately responsible for the correct and controlled operation of the rig.
In case of doubt, the tests should be carried out in a Faraday cage.
1.4. General hazard
Before applying power to the system, verify that your product is configured properly for your particular application.
WARNING
The generators and their accessories operate at high voltages.
Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme
caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above (below) chassis ground.
The design of external insulation must be such that it exceeds the maximum impulse voltages of the
generator (5.5 kV or 7.0 kV).
Only qualified personnel who deal with attendant hazards in impulse generators, are allowed to perform installation and
servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis. Similarly, other
power ground lines including those to application and maintenance equipment must be grounded properly for both personnel
and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
The user must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent
contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even
when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal
injury by any sudden component failure.
Neither AMETEK CTS GmbH, nor any of the subsidiary sales organizations can accept any responsibility for personnel,
material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.
