This service information is designed for experienced repair technicians only and is not designed for use by the general public. It does not 
contain warnings or cautions to advise non-technical individuals of potencial dangers in attempting to service a product. Products 
powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the 
product or products deal within this service information by anyone else could result in serious injury or death. 

 

 

 

 

 

 

1.  When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated 

or damaged by the short circuit. 

2.  After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly 

installed. 

3.  After servicing, make the following touch current checks to prevent the customer from being exposed to shock hazards. 
4.  Always ensure cover label TBM4GU113 is correctly replaced before returning to customer (see Fig.1). 
 
 
 
 
 
 
 
  
 
 
 
 
 
 

1.  Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 
2.  Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth 

ground such as a water pipe, as shown in Fig. 2. 

3.  Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network. 
4.  Check each exposed metallic part, and measure the voltage at each point. 
5.  Reserve the AC plug in the AC outlet and repeat each of the above measure. 
6.  The potential at any point (TOUCH CURRENT) expressed as voltage U1 and U2, does not exceed the following values: 

For a. c.: U1 = 35 V (peak) and U2 = 0.35 V (peak); 
For d. c.: U1 = 1.0 V, 

Note:

 

The limit value of U2 = 0.35 V (peak) for a. c. and U1 = 1.0 V for d. c. correspond to the values 0.7 mA (peak) a. c. and 
2.0 mA d. c. 
The limit value U1 = 35 V (peak) for a. c. correspond to the value 70 mA (peak) a. c. for frequencies greater than 100 
kHz. 

7.  In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should 

be repaired and rechecked before it is returned to the customer.
