ONNECTION OF THE REMOTE MAINTENANCE BYPASS 

 

An additional maintenance bypass can be installed on a peripheral electric control panel, for example to replace the UPS 
without interrupting power to the load. 

 

 

It is essential to connect the SERVICE BYPASS terminal (

see "View of UPS connections", point 2) to 

the auxiliary contact of the SERVICE BYPASS switch. Closing the SERVICE BYPASS switch (4), will 
open this auxiliary contact which signals the insertion of the maintenance bypass to the UPS. 

Absence 

of this connection could interrupt the power to the load and cause damage to the UPS. 

 

NOTE:   use cables with a cross-section compliant with the indications given in the “Cable Sizes” section.  
 Use 

1mm

cables with double isolation to connect the SERVICE BYPASS terminal to the auxiliary contact of 

the remote maintenance bypass disconnecting switch. 

If the UPS is fitted with an internal isolation transformer, ensure compatibility between the remote 
maintenance bypass and the neutral arrangements.
