2.

 

Check that the input voltage polarity is correct. 

3.

 

Check that the input voltage is within the 
specified limits, see front label.  

4.

 

The converter may be in current limit due to 
excessive output current or an external short-
circuit on the output. 

 

Disconnect the input. 

 

Disconnect the load.  

 

Connect the input again and measure the 
output voltage.  

If the converter now starts the load was too 

heavy or there was a short-circuit.  

 

If there is an external short-circuit, remove 
it. 

 

If the load is too large, decrease the load or 
consult your Polyamp dealer. 

5. 

 

The unit is broken. Contact your Polyamp 
dealer. 

 

6.2

 

The input fuse blows when the input 
is connected 

1.

 

Check that the input voltage polarity is correct. 

2.

 

Check that the input fuse is of time 
delay type and with correct current 
rating. See 

Table 1

3.

 

The unit is broken. Contact your Polyamp 
dealer. 

 

6.3

 

The converter starts and stops 
repeatedly 

1.

 

The converter may be in current limit due to 
excessive output current, a too capacitive load 
or an external short-circuit on the output. 

 

Disconnect the input. 

 

Disconnect the load.  

 

Connect the input again and measure the 
output voltage.  

If the converter now starts the load was too 

heavy or too capacitive or there was a short-
circuit.  

 

If there is an external short-circuit, remove 
it. 

 

If the load is too large, decrease the load or 
consult your Polyamp dealer. 

 

If the load is too capacitive (approximately 

>

1000

µ

F), consult your Polyamp dealer.
