COMMUNICATION CABLES can enter the top or bottom of the UPS. Connection area is recessed below an acrylic cover so all cables are below the top panel skin. No front access is required. No requirement to go into bypass or shutdown power to access this area.

Liebert® EXL™ S1

TOUCHSCREEN CONTROL PANEL is intuitive to use, consistent with other Vertiv touchscreens, has customer configurable data and views, multiple user security levels and Status-At-A-Glance LED light.

STANDARD INPUT / OUTPUT cabinet offers top or bottom cable entry and optional single input jumpers.

Back Feed Disconnectect

Optional BACK FEED DISCONNECT (BFD) isolates back feed voltage from the upstream source, eliminating the need for a shunt trip accessory in the external upstream back feed breaker.

Sharing Inductors (SI)

Rectifier input, bypass, output & DC bus bars accessible in a SINGLE CABINET.

Common Mode Choke (CMC)

Top or bottom CABLE ENTRY for easy and flexible installation. Copper and Aluminum cables supported.

STRATEGICALLY SPACED BUS BARS for easy cable routing and termination. Expanded DC bus bars provide additional space for battery conductor terminations.

CONTROL BOARD SECTION houses all main PCBs in a single compartment.

CONTINUOUS DUTY STATIC SWITCH with dual speed thermostatically controlled AC centrifugal fans. This robust static switch has a high overload capability and works in conjunction with Liebert EXL S1 controls to provide fast transfers (<2 ms) from ECO mode.

600kVA/kW POWER CORES provide the highest available power density in this size UPS. Offers double conversion efficiency up to 97%.

SINGLE INPUT JUMPERS provide simple solution to single input applications.

MONITORED DC VARIABLE SPEED FANS (100,000 hour life) provide efficient front to top cooling. Liebert EXL S1 will continue to operate at full load after a fan failure depending on temperature and loading.

Back Feed Disconnect (BFD)

Optional SHARING INDUCTORS may be installed to ensure parallel UPS modules share the load evenly when powering the load through their static bypass switches. Some applications may require this option when it is difficult or impossible to match parallel UPS cable length

Sharing Inductors

Optional COMMON MODE CHOKE may be installed for applications that require dual asynchronous source input (i.e., applications where the rectifier and bypass input of the UPS are not fed from the same solidly grounded wye source).
