Hazardous

 

Voltage 

 

 

HAZARDOUS VOLTAGE.  Disconnect before working on product 

DC supply voltage up to 300V, (+0V tolerance). 
 

DUAL SUPPLY. Disconnect both supplies before working on the product 

Hazardous voltage may be present on DC supply and 

PR-

, 

HV-SW-,

 

HV-SW+

 and 

PR+

 terminals. 

 

DISCONNECT DEVICE(S) 

Each Hazardous Voltage circuit which connects to the ITR shall incorporate a 
readily accessible disconnect device installed externally to the ITR. 
Disconnect devices shall have contact separation of at least 3mm. 
 

 

 

ITR Terminals 

 

 
 

 

HAZARDOUS VOLTAGE.  Stray conductors or loose connections. 

Provide insulation and strain relief on all Hazardous Voltage terminations to 
protect against electric shock hazard.
