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

Isolation voltage
Signal input:
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 28.1 for application notes.

Restriction apply when using the signal and relay contacts in a Haz-Loc environment:
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.

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.
