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.
