1. Safety instructions  

The 5 kV high voltage power supply conforms to all 
safety regulations for electrical measuring, control, 
monitoring and laboratory equipment, as specified 
under DIN EN 61010, Section 1, and the equipment 
has been designed to meet protection class I. It is 
intended for operation in a dry environment, suit-
able for the operation of electrical equipment and 
systems.    

Safe operation of the equipment is guaranteed, 
provided it is used correctly. However, there is no 
guarantee of safety if the equipment is used in an 
improper or careless manner.      

If it may be assumed for any reason that non-
hazardous operation will not be possible (e.g. visi-
ble damage), the equipment should be switched off 
immediately and secured against any unintended 
use.      

In schools and other educational institutions, the 
operation of the power supply unit must be super-
vised by qualified personnel.      

 

Before using the power supply unit for the first 
time, confirm that the specifications printed 
on the rear side of the housing are compatible 
with the local mains voltage. 

 

Before using the power supply unit for the first 
time, check the housing and the mains lead for 
any damage. In the event of any malfunc-
tion/operational defect or visible damage, 
switch off the unit immediately and secure it 
against unintended use.      

 

The instrument may only be connected to the 
mains via a socket that has an earth connec-
tion. 

 

Before making any connections, check the 
experiment leads for damaged insulation and 
exposed wires.    

 

Replace a faulty fuse only with one matching 
the specifications stated at the rear of the 
housing.      

 

Disconnect the equipment from the mains 
before replacing a fuse.   

 

Never short the fuse or the fuse holder.    

 

Never cover the air vents in the housing. This is 
necessary in order to ensure sufficient circula-
tion of air required for cooling the internal 
components of the equipment.    

 

The equipment may only be opened/repaired 
by qualified and trained personnel.
