The DC-UPS is equipped with relay contacts and signal inputs for remote monitoring and controlling of the unit. 

 

Ready: 

Contact is closed when battery is charged more than 85%, no wiring failure are recognized, input 
voltage is sufficient and inhibit signal is not active. 

Buffering:  

Contact is closed when unit is buffering. 

Replace Battery: 

Contact is closed when the unit is powered from the input and the battery quality test (SOH test) 
reports a negative result.

Inhibit: 

The inhibit input disables buffering. In normal mode, a static signal is 
required. In buffer mode, a pulse with a minimum length of 250ms is 
required to stop buffering. The inhibit is stored and can be reset by 
cycling the input voltage. See also section 27.1 for application hints.

The Buffering, Ready and Replace Battery contact is intended to be used for a separately investigated nonincendive field wiring 
and/or field wiring apparatus. The DC-UPS may be located in a Class I, Division 2 (Group A, B, C or D) hazardous (classified) 
location. Associated apparatus must be installed in accordance with its manufacturer's control drawing and Article 504 of the 
National Electrical Code (ANSI/NFPA 70) for installation in the United States, or Section 18 of the Canadian Electrical Code for 
Installations in Canada.  
Selected associated apparatus must be third part listed as providing nonincendive field circuits for the application, and have Voc 
not exceeding Vmax, Isc not exceeding Imax. 
 
Non associated nonincendive field wiring apparatures shall not be connected in parallel unless this is permitted by the associated 
nonincendive field wiring apparatures approval.  

June. 2010 / Rev. 1.3  DS-UB10.241-EN 
All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time  
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.
