We recommend reading this document before installing the equipment, which must be operated only by qualified personnel.
Introduction Liebert EXL S1 1.3. Terms used 1.3.1. Service Bypass A switch that provides continuous supply to the load via the bypass input power line during maintenance work; also referred to as the maintenance bypass. 1.3.2. Static Bypass Switch A thyristor switch which connects the load directly to the power line; also referred to as a static switch or static bypass.
(built to IP20, with optional filters available for special conditions). However, it is not possible for Vertiv to ensure that foreign bodies will not be introduced during on-site installation, or when the UPS doors & covers are "open" and the electrical terminals are exposed to allow power line connections to be made by the electrical contractor/installer.

Liebert EXL S1 Installation 3.8. Connecting the batteries UPS are supplied without the battery switch. It is mandatory that the Customer provides an external battery protection device, ensuring that they are correctly rated. Auxiliary signal contacts shall be assigned to a programmable input of XP11, so that the status of the switch can be monitored during the normal operation.
Installation Liebert EXL S1 Notice The most common battery type used in UPS installations is the valve regulated battery. Valve regulated cells are not sealed. The amount of gas given off is less than for flooded cells, but when planning the battery installation, allowance must be made for adequate ventilation and heat dissipation.

Liebert EXL S1 Normal and safe operation 5. NORMAL AND SAFE OPERATION 5.1. Function The uninterruptible power supply (UPS) is connected between line power and electrical load. It protects the load from line power interruptions and power failures. Warning To avoid overheating inside the UPS, do not operate the unit for extended periods with the rectifier running, the Inverter switched off and the Bypass switch open.
Normal and safe operation Liebert EXL S1 5.1.4. Communication The UPS offers several interfaces for communication with computers. Further information is included in chap. 4. on page 5.2. Special features 5.2.1. Safe and reliable operation • Real on-line functioning, i.e. complete de-coupling of the load from all abnormalities in line power •...
5.4. Maintenance Bypass Switch (not available for 600/800/1000/1200kVA) Liebert EXL S1 is equipped with a Maintenance Bypass Switch (QS3) that allows the user to perform maintenance on the UPS without interrupting the supply to the load. Transfer to and from Maintenance must be done in accordance with the procedures 3 and 4 described in para 5.7.
Normal and safe operation Liebert EXL S1 5.5. Operating modes The UPS has four different operating modes. These are described below. 5.5.1. On-line operation Normal UPS operating mode. The connected loads are supplied from line power via the Inverter. The batteries are charged as necessary.
Liebert EXL S1 Normal and safe operation 5.5.3. Bypass operation In this operating mode, the connected loads are supplied from line power via the Static Bypass Switch. The Static Bypass Switch is used to provide power to the loads. If an overload or short-circuit on UPS output occurs, the Static Bypass Switch is automatically activated to provide uninterrupted power to the loads.
Normal and safe operation Liebert EXL S1 5.6. Placement into service 5.6.1. Forming If the UPS devices have not been used for one year or more, the intermediate circuit capacitors must be reformed. If the UPS devices are placed into service within one year after delivery (check nameplate), this action is not necessary.
Liebert EXL S1 Normal and safe operation 5.7. UPS switching procedures The following procedures refer to para 5.3. on page Warning If static switch module and relative switches are not assembled, refer to MSS user manual. 5.7.1. Procedure 1: UPS TURN-ON PROCEDURE Starting with the UPS completely deenergized, this procedure explains how to switch on the UPS and set it to Normal Operating Mode.
Normal and safe operation Liebert EXL S1 5.7.3. Procedure 3: TRANSFER FROM NORMAL MODE TO MAINTENANCE BYPASS MODE Starting with the UPS in the Normal Mode, this procedure explains how to transfer the load to Maintenance Bypass and shut down the UPS.
Liebert EXL S1 Normal and safe operation 5.8. Inverter STOP/START procedures 5.8.1. Single UPS - Start Inverter UPS in Bypass mode: To start the inverter and transfer the load to the inverter touch ‘Inverter On’ on the touch screen. 5.8.2.

6. MAINTENANCE 6.1. Maintenance intervals Vertiv recommends that regular maintenance checks be carried out on-site by an authorized customer service. The UPS informs the user when the normal service life of a fan has ended. A replacement fan is recommended.
PARALLEL CONFIGURATION 7. PARALLEL CONFIGURATION Up to 8 Liebert EXL S1 units can be connected in parallel to increase power capacity and thus to provide more secure power to the load (redundancy). The modules in parallel exchange information via a 37-wire shielded cable.
PARALLEL CONFIGURATION Liebert EXL S1 7.3. Communication between UPS blocks UPS units exchange information through the connector cable (37 pin connector). Fig. displays the loop circuit, which is electronically monitored. The communication cables are shielded and must be run separately and away from the power cables.
Liebert EXL S1 PARALLEL CONFIGURATION 7.4.2. Procedure 2: UPS TURN-OFF PROCEDURE Starting with each UPS in Normal Mode, this procedure explains how to switch off the UPS units. When this procedure is followed completely, the output voltage will be completely turned off and any load(s) connected to the UPS output will be shut down.
PARALLEL CONFIGURATION Liebert EXL S1 7.4.4. Procedure 4: TRANSFER FROM MAINTENANCE BYPASS MODE TO NORMAL MODE Starting with each UPS in Maintenance Bypass, this procedure explains how transfer the load to Normal Mode and start the UPS. On each UPS, perform the following procedure:...

Technical data Liebert EXL S1 The modules cabinet is 2100mm wide and the switches cabinet is 750mm wide. The sum of these two widths is greater than the width of the fully assembled unit, which is indicated in the table. This difference is due to the protrusion of some connecting bars and closures from the modules cabinet, which need to be assembled to the switches cabinet during the installation in field.
