1 I MPORT A NT S AFETY I NSTRUCTIONS SAVE THESE INSTRUCTIONS This manual co ntains important ins tructions that shoul d be followe d during the ins tallation and maintenance of the Liebert STS2. ! WARNING The unit is supplied by more than one power source.
2 O VERVIEW OF M ANUAL The Liebert STS2 Instal lation, Opera tion and Maintenance Manu al is organized in a logical progression so that you can follow the procedures in the order provided to get your Liebert STS2 installed and run ning. Read the entire manual before proceeding w ith the unpacking and i nstallation of the Liebert STS2.
Safety Precautions 3 1.0 S AFETY P RECAUTION S Read this manual thoroughly before working with the Liebert STS2. Be sure to review the warning under Important Safet y Instructions on page 1 . Refer to the Handling Considerations on page 5 before attempting to move the unit.
Unpacking and Inspection s 4 2.0 U NP ACKING AND I NSPECTIONS A high-quality installation begins on the receiving d ock. The Liebert STS2 and its packag ing should be inspected when the unit is deli vered. If the packaging is not da maged, unpack the unit and conduct an internal inspect ion before beginning the installa tion process.
Unpacking and Inspection s 5 2.2.1 Handling Considerations The static switch is bolted to a wooden shipping pall et to allow handling by forklift equipmen t or a pallet jack. Easily Moved — The unit is furnished with i ntegral castors t hat allow the unit to be rolled in to place after it has reached its location and is removed from the pall et.
Location Cons iderations 6 3.0 L OCATION C ONSIDERATIONS The Liebert STS2 should be placed in a clean, cool and dry location . The Liebert STS2 requires o nly front access for install ation and maintenance. Back or side access is not required. Adequate space is required above the unit for conduit (i f configured as such) and cooling air flow .
Location Cons iderations 7 3.4 Altitude The standard units are designed for full load operation up to 4000 feet (1200m) abov e sea level. See Figure 1 for recommended deratings for altitu des greater than 4000 feet (1200m).
Locating the Lieb ert STS2 8 4.0 L OCATING THE L IEBERT STS2 This section provides instru ctions for leveling th e Liebert STS2 and anchoring the unit to the floor, should that be required.
Power and Con trol Wir ing 9 5.0 P OWER AND C ONTROL W IRING All power and control wiring should be installed by a qualif ied electrician. All power an d control wiring must comply with the NE C and applicable local codes. Unless otherwi se labeled, use the recommended tightening torque as shown in Table 24 - Torque tightening.

Operating Instructions for the Touch Screen Interface 69 10.4.1 Byp ass Procedures for Source 1 To bypass the swit ch for Source 1: 1. Verify that Source 1 is supplyin g power via the Mimic. • If the Color Gr aphical Display i s not availabl e, check the gate drive r board LEDs thro ugh the slots in the control pan el.
Operating Instructions for the Touch Screen Interface 70 10.4.2 Byp ass Procedures for Source 2 To bypass the swit ch for Source 2: 1. Verify that Source 2 is supplyin g power via the Mimic. • If the Color Gr aphical Display i s not availabl e, check the gate drive r board LEDs thro ugh the slots in the control pan el.
Alarm and Faults 71 11 . 0 A LARM AND F AULT S Alarms and faults are events that are triggered wh en the operation of the Liebert STS2 falls outside the defined parameters. These events can also be triggered by: user actions, such as cha nging configurations, clearing logs, etc.
Alarm and Faults 72 1 1.2 Event and History Logs The system tracks events through the Events Log and tracks sig nificant ev ents through the History Logs. These logs allow you to quickly spot trends or diagnose problems that the unit may have had. Both logs are written in nonvolatile memory.
Alarm and Faults 73 The History Log has the following fiel ds: • Replay Rate — indicates how l ong it take s for t he replay to pl ay. Use the UP and DOWN b uttons to set the time. • Status — the status of the Liebert STS2 at the po int of the current fram e in the replay.
Alarm and Faults 74 T able 8 Event messages ID Alarm Message Description/Cause Action 001 S1 SCR SHORT One or more of the SCRs for Source 1 have shorted an d fail ed. D, F, A, E 002 S2 SCR SHORT One or more of the SCRs for Source 2 have shorted an d fail ed.

Communication Interfaces 76 12.0 C OMMUNICATION I NTERFACES The Liebert STS2 monitoring system of fers several choices for communications. The RS-232 te rminal port is standard on all un its. Th e port is located inside the front door, to the left of the touch screen/LED front panel mounting as shown in Figure 28 .
Communication Interfaces 77 12.1.1 Connecting and Using a T erminal An RS-232 connection can be used to connect the Liebert STS2 to either a terminal or a PC running terminal emulation software . If you ar e unsure of the cable pin out, see 15.2.10 - Terminal Port Connections .
Communication Interfaces 78 12.1.2 Configuring the Lie bert STS2 via the T erminal The SPT command is used to configure the syst em s setpoints. The SVT sy ntax for the setpoints consists for four parameters: SPT [ group ] [ item ] [ value ] where the parameters are: • SPT — is the terminal command that is used to configure setpoints.
Communication Interfaces 79 Va l u e P a r a m e t e r Item settings, depending on what they are, use various value types. Table 10 provides a list of the possible value types and their descript ion. Table 11 shows the variou s groups, the settings co ntained within, and th e type of value it requi res.
Communication Interfaces 80 Group 3: User Settings 1 SCR1 Fast Undervoltage Setpoint Integer In % of nominal below nomin al 2 SCR1 Slow Undervoltage Setpoint Integer In % of nominal below nomin al 3 S.
Communication Interfaces 81 12.1.3 Setting Bitp acked Options with the T erminal Five sets of options and features settings are available through the terminal to control the system operation.
Communication Interfaces 82 Critical Option Enabling bit0—EnableManual_IPeakReset bit1—EnableAutoRestart bit2 through bit15 - not used (set to 0) Non-Critical Optio n Enabling bit0 — EnableAutoReXfer bit1 through bit15 — not used (set to 0) The bits are set in reverse orde r, from bit 15 on th e le ft to bit 0 (zero) on the right.
Communication Interfaces 83 Putting the T erminal Command T ogether For example, a unit only has the Remote Source Se lection and Dual-Output Breaker opti ons installed. Checking the bits list under Options_1 on page 81 , bits 7 and 0 each must be set to 1 to indicate that these option s are installed.
Communication Interfaces 84 12.1.4 Setting Event Masks with the T erminal The event masks can be customized via a terminal . The command SPT4?<ENTER> displays all fault s and alarms, along with t heir asso ciated event masks. A plus sign (+) means that particular event mask is enab led, while a min us sign (-) means that mask is disabled.
