Provide surge protection. Filter electromagnetic interference (EMI) andradio frequency interference (RFI). Minimize surges or interference present in the utility power and protect devices connected on the same branch as the UPS.
Continuouslyfloat-charges the batteries from precisely-regulated utility power whenever the UPS is plugged in.
Valve-regulated, non-spillable, lead-acid batteries.
NOTE: To maintain battery design life, operate the UPS in an ambient temperature of 59°F to 77°F (15°C to 25°C).
Raises the DC voltage from the battery to the optimum operating voltage for the inverter. This allows the inverter to operate continuouslyat its optimum efficiency and voltage, thus increasingreliability.
In normal operation, converts utility ACpower to regulated DC power for use bythe inverter while ensuring that the wave shape of the input current used bythe UPS isnear ideal. Extracting this sine-wave input current ensures efficient use of utility power and reduces reflected harmonic distortion making cleaner power available to devices that are not protected bythe UPS.

6 Inverter
7 Internal Bypass
8 Outlet group Output receptacles.
When utility power fails, the inverter receives DC power from the DC-to-DC converter. In either operating mode, the UPS inverter remains on-line, generating clean, precise, regulated AC-output power.
In the unlikelyevent of UPS failure such as overload or over-temperature, automatically transfers the connected load to bypass.
To manually transfer the connected load from inverter to bypass, see Transferring from Normal to
Bypass Mode on page40.

1.6.1 Maintenance Bypass

On 5-kVA to 10-kVA models, the UPS includes manual maintenance bypass in a removable section of the rear of the UPS. Maintenance bypass keeps connected equipment powered with utility power and allows replacement of the UPS in the event of a UPS malfunction.
NOTE: The bypass power path does not protect the connected equipment from disturbances in the utility power supply.

1.7 UPS States and Operating Modes

NOTE: See LED Indicators on page42, for description of the run-indicator and alarm-indicator LEDs mentioned in this section.

1.7.1 Normal Mode

When utility power is normal, Normal mode employs the rectifier and inverter to provide voltage- and frequency-stabilized power to the load. The charger charges the battery in normal mode. On the front­panel display, the run-indicator (green)is On, the alarm indicator is OFF, and the buzzer is silent. Figure
1.13 on the facing page, shows a diagram of normal mode.

1.7.2 Bypass Mode

Bypass mode supplies power to the load from the bypass source (utility power) if an overload or fault occurs during normal operation. On the front-panel display, the run indicator (green) is On, the alarm indicator (yellow)is On, and the buzzer beeps once each seconds. The LCD "Current" screen displays "On Bypass." Figure 1.14 on the next page, shows a diagram of bypass mode.
NOTE: If utility power fails or if the utility voltage goes outside of the permissible range during bypass­mode operation, the UPS shuts down and no output is supplied to the load.

1.7.3 Battery Mode

Battery mode supplies battery power to the load if utility power fails or if the utility voltage goes outside of the permissible range. On the front-panel display, the run indicator (green) is On, the alarm indicator (yellow)is On, and the buzzer beeps once each second. The LCD "Current" screen displays "On Battery." Figure 1.15 on the facing page, shows a diagram of battery mode.
NOTE: The batteries are fully-charged before shipment. However, transportation and storage inevitably cause some loss of capacity. To ensure adequate back-up time, charge the batteries for at­least 8 hours before first start-up.
NOTE: If utility power fails and the batteries are charged, you may cold-start the UPS in battery mode and use battery power to extend system availability for a time.

1.7.4 ECO Mode

NOTE: ECO mode is only available on a single-UPS system.
The energy-saving ECO mode reduces power consumption by powering the load via bypass if the bypass voltage is normal or by powering the load via the inverter when the bypass voltage is abnormal. You can use ECOmode to power equipment that is not sensitive to power-grid quality to via bypass and reduce power consumption.
NOTE: During Eco mode, if a bypass-failure or abnormal-bypass-voltage notification appears when the output is not overloaded, the UPS will transfer to Normal Mode. However, if a notification showing bypass failure or abnormal bypass voltage appears when the output is overloaded, the UPS will shut down the bypass.

Page 22

1.7.5 Maintenance Bypass Mode

NOTE: 5-kVA to 10-kVA models include an MCB to switch the load to bypass. On 16-kVA to 20-kVA models, a dry contact may be used to trigger maintenance bypass.
Used when the UPS requires maintenance or repair, Maintenance-bypass mode powers the connected equipment with utility power while electrically isolating the internal UPS components.
NOTICE
Risk of power interruption. Can damage the connected equipment.
If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode, the UPS may shut down without notice and shut-off output power to the load.
NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit http://www.VertivCo.com/en-us/support/ or contact your local Vertiv representative.

2.6.1 Branch Circuit Breaker

The installer must provide an upstream branch circuit breaker, see Table 2.2 below, for the ratings. The input circuit breaker on the distribution box and the output circuit breaker on the rear of the power distribution box disconnect all power between the main cabinet and the distribution box. Figure 2.4 on the facing page, shows a diagram of the circuit breakers.
Observe the following guidelines and specifications when making the hard-wire input and output connections:
Provide circuit-breaker protection according to local codes. The mains disconnect should be within sight of the UPS or have an appropriate lock-out.
Maintain service space around the UPS or use flexible conduit.
Provide output-distributions panels, circuit-breaker protection, or emergency disconnects according to local codes.
Do not install input and output wiring in the same conduit.
Models equipped with a manual bypass breaker pass bypass power directly to the bypass breaker from the input terminal block. The input circuit breaker on the distribution box does not disconnect power from the manual bypass breaker.

2.7.3 Connecting a Remote Emergency Power-off (REPO) Switch

The UPS includes an EPO connection in the dry-contact port. See the appropriate figure for your model in
Rear Panels on page4, for the location of the port.
UPS ships with a REPO jumper installed, allowing the UPS to operate as a normally-closed switch system (fail-safe). Opening the circuit disables the UPS. To connect a REPOswitch that opens the circuit to shut down the rectifier and inverter and power-off the UPS, use a cable from the remote switch to plug into the REPO-port on the UPS.
33
Page 38
In normal conditions, the REPO switch cannot cut off the UPS input power. When the REPO switch trips, the UPS generates an alarm and immediately cuts-off output power. When the emergency condition is resolved, the UPS will not return to normal operation until you reset the REPO switch and manually power­on the UPS.
To make the cable for the REPO connection:
Figure 2.11 below, shows the cable required to make the connection. We recommend using 18AWG to
33AWG (0.82mm2to 0.33mm2) copper-core cable.
1. Remove the insulation from the end of two cables.
2. Insert the stripped end into the plug terminals 1 and 2 respectively, then press down the terminals. Make sure that the cables are secure in the plug to prevent failure because of loose contact.
To connect a UPS to the REPO switch
CAUTION: To maintain safety (SELV) barriers and electromagnetic compatibility, signal cables should be shielded and run separately from power cables.
1. Connect one end of the cable to the remote switch, see Figure 2.11 below.
2. Remove the factory-installed jumper from pins 7 and 8 of the dry-contact port on the UPS
3. Connect the plug to pins 7 and 8.

2.8 Installing a Parallel System

10-kVA, 16-kVA, and 20-kVA models may be configured in a parallel system. The UPS parallel system provides N+X(1≤N+X≤3,X=0or1) parallel configuration. Nstands for the basic parallel sets, Xstands for the redundant sets.
All electrical requirements, including external-distribution panel and branch circuit breaker, apply to each UPS in a parallel system, which are then connected in ring configuration for redundancy and additional reliability. System load information can be accessed via any controller/display in the system.
The following are requirements for the parallel-connected system:
Each UPS must have the same capacity and must be connected to the same mains/utility source.
If a residual-current detector (RCD) is required, if must be correctly-set and installed before the same neutral-line input terminal. See safety and regulatory information, available at
https://www.vertivco.com/ComplianceRegulatoryInfo.
The output of each ups must be connected to the same output bus.
2 Installation
35
Page 40
The parameter configuration for each UPS must be identical.
Because the parallel system is not fitted with auxiliary-contact detection devices for the output circuit breaker or the maintenance-bypass circuit breaker of each UPS, You must strictly-follow the procedures for transferring between operating modes when removing a single UPS from the parallel system before maintenance and when adding a single UPS after maintenance. Failure to observe the procedure may affect the reliability of the load power supply.
Figure 2.12 below, shows an example of the 10-kVA model connected as a 2+1parallel system connected in a ring configuration.
NOTE: 8-kVA models do not support parallelling at this time.
NOTE: You must use Vertiv parallel cables for the connection.
NOTE: If a fault occurs during parallel-system operation, shut-off the system and make sure the cables are connected correctly, see Figure 2.12 below.
CAUTION: Risk of improper disconnection. Can equipment damange. Do not disconnect parallel-system cables while the system is operating.
