Liebert STS2 Communication and Product Options

Liebert STS2 Communication and Product Options

Liebert STS2 has a wide choice of monitoring and

communications options to keep you connected to your

critical power protection system.

RS-232 Terminal Port — Standard on all units, this port is primarily used as an alternate user interface to configure, control, and diagnose the system.

Input Contact Isolator (ICI) Board — Customizable input relays allow alarms from other devices to be displayed on Liebert STS2 display. Provides an interface for up to eight user inputs. External messages and alarms can be routed to the unit, via the ICI.

Programmable Relay Board (PRB) — Programmable output relays for custom customer alarms and connections. Up to two PRBs can be installed in the Liebert STS2 to route system events to external devices.

Comms Board — Includes a terminal block to provide a DTE connection to an external modem. This board also provides a direct connection to a Liebert SiteScan® Web system, via an RS-422. SiteLink-12 or SiteLink-4 is required for SiteScan to communicate with the Liebert STS2.

Liebert IntelliSlot™ 485 Web Card ADPT

Allows systems to be viewed from the network using a web browser.

Delivers SNMP, Telnet and web management.

Provides security using HTTPS message encryption.

Supports 10 and 100 MBit Ethernet for legacy and modern networks.

Provides compatibility with Liebert MultiLink shutdown software, to prevent data loss and ensure data availability.

Supports Liebert SiteScan WEB enterprise monitoring software, to provide trending for proactive analysis and maintenance to ensure facility uptime.

Interfaces to Liebert Nform alarm notification software, to facilitate quick corrective action.

Liebert IntelliSlot 485 Web Card ADPT provides connectivity to any TCP/IP-based Ethernet network to allow the device to communicate with network management systems (NMS) via SNMP. Events can be transmitted to the NMS to provide remote status monitoring,

plus fault and alarm detection. The card includes an RJ-45 port for an Ethernet connection, via Category 5 cable. The card can also integrate the system with an existing Building Management System (BMS) or out-of-band monitoring, using Modbus.

Options and Accessories

Seismic Anchors — To ensure stability for the unit in the event of seismic activity, anchors are available for securing the unit to a concrete floor to meet seismic Zone 4 requirements.

Seismic Floor Stand — Designed to level the unit and provide bottom cabling access without relying upon a raised floor for support. Available in 18, 24, 30, 36 inch heights.

Distribution Cabinet (Up to 600A) — An output distribution cabinet mounts on the side of the STS2. It is a full height section with hinged doors to allow for easy access. The cabinet contains one vertically mounted I-line panelboard for load distribution. The panelboard is totally enclosed with an accent cover that provides access without exposing other portions of the unit. The panelboard provides space for 100A through 250A three-pole branch circuit breakers. It also includes a separate isolated neutral bus bar and safety-ground bus bar for the neutral and safety-ground connections.

Redundant Output Breaker — An output plug-in, non- automatic circuit breaker provides redundancy in the output power path. The breaker is connected in parallel with the output plug-in non-automatic circuit breaker.

Input Junction Boxes and Cable (Up to 600A) — The input junction box option is available to simplify input connections to the STS2. Two input junction boxes and the associated flexible 10-foot long input cables are provided with this option. Available with bottom cable entrance only, typically when the unit is located on a raised floor.

Remote Source Selection — An optional Remote Source Selection board may be installed in your STS2. This option allows you choose the preferred input source from a remote location. Terminal connections enable you to remotely select a preferred source in the same process as the local source transfer selection.

Key Lockout Switch — The key lockout switch activates a software lockout of the touch-screen display to prevent manual transfers and configuration changes. When locked out, the touch-screen becomes a read only display. A key is needed to perform manual transfers or change settings.
