Figure 2.12 Operating principle diagram
Vertiv | Liebert® APS™ Installer/User Guide |
21
2.5 Operating Modes
The Liebert APS is a true online double-conversion system, with the following operating modes:
•
Normal Mode
•
Backup Mode
•
Auto Restart Mode
•
Bypass Mode
2.5.1 Normal Mode
The power-module rectifiers derive power from a utility AC source and supply regulated DC power to the
inverter. The module’s inverter regenerates precise AC power to supply the connected equipment. The
battery charger is in the power module and maintains a float-charge on the batteries of the UPS. The
optional charger module can also charge the batteries to maintain a quicker recharge time for long backup time applications.
2.5.2 Backup Mode
When AC utility fails, the connected equipment is supplied power by the inverter, which obtains energy
from the battery modules. The output power will not be interrupted during the failure or restoration of the
AC utility/mains source.
2.5.3 Auto Restart Mode
After a power outage and complete battery discharge, and once AC utility is restored, the UPS
automatically restarts and resumes supplying power to connected equipment. This feature is enabled at
the factory, but can be disabled by you. You can also program two auto-restart delay settings from the
LCD:
•
Battery capacity level (%)
•
Countdown timer
2.5.4 Bypass Mode
The bypass provides an alternate path for power to the connected equipment and operates as follows:
•
Automatic: In the event of an internal fault or the inverter overload capacity be exceeded, the
UPS performs an automatic transfer of the connected equipment from the inverter to the
bypass source.
•
Manual: If the UPS needs taken out of service for limited maintenance or repair, manual
activation of the bypass causes an immediate transfer of the equipment from the inverter to
the bypass source.

3.3.1 Installation Site Considerations and Clearances
Consider the weight and size of the Liebert APS when deciding where to install the unit. Verify that the
floor can support the weight of a fully-loaded unit, with any accessories and external cabinets.
The UPS is air-cooled by internal fans. Air is drawn into the front of the UPS and exhausted through
ventilation grilles in the back. Verify that the UPS will be in a well-ventilated area with at least 6-in.
(153-mm) clearance behind for ventilation and at least 39-in. (1-m) clearance in front for service and to
meet local and national building codes.
3.4 Removing the UPS from the Pallet
The unit frame is bolted to the shipping pallet for safety during shipping. We recommend keeping the
unit bolted to the pallet and using a pallet jack to transport the unit to the installation location.
NOTE: The UPS is very heavy. At least two people should unload it from the pallet.
To unload the UPS:
1.

3.7.2 Connecting Cables on a Transformer-Based UPS
NOTE: After the output transformer is installed, if the start-up is on bypass, the UPS has a 6-cycle
inrush current that is up to 20 times the rated output current. This must be taken into account when
selecting the input-overload protection device at the AC-input supply-distribution point.
To avoid random tripping on startup, we recommend that the AC-input supply be protected with a
circuit breaker capable of withstanding this initial inrush (the MCB is derated according to the D curve
or TYPE 4).
This UPS is fitted with EMI filters. Earth leakage current is less than 40 mA. Transient and steady-state
earth leakage currents may occur when starting the UPS. This should be taken into account when
selecting transient RCCB or RCCD (leakage-current devices of the UPS and load).
The MCB of the AC power supply connected to the UPS input must bear this warning:
"Disconnect the connection with UPS before maintaining this circuit"
The warning is required because the UPS has no auto-feeding protection device.
The UPS grounding should be in accordance with local regulations.
A junction box is factory-installed on all models of the Liebert APS to ease cable connection.
Select the appropriate input cables according to Table 3.5 on the facing page and Table 3.6 on the
facing page based upon the UPS rating and mains frequency. Emerson recommends sizing the frame’s
overcurrent protection and wiring to permit easier UPS system upgrades.

Configuring the Bypass Voltage
The UPS bypass voltage is factory-set to 208 V (the jumper copper bar is installed). If you have a utility
supply of 200 V/220 V/230 V/240 V, you must change the bypass-voltage jumper to ensure correct
output voltages when in bypass mode. The bypass voltage jumper settings are shown in Figure 3.17 on
the next page and Figure 3.18 on the next page. Refer to Table 3.8 on page 41 for the proper setting
according to the AC mains voltage configuration.

Configuring the Neutral/Earth Jumper
The UPS contains an isolation transformer that generates a neutral conductor for the connected load.
The UPS is a separately-derived source and contains a neutral/earth jumper. You may need to remove a
factory-installed neutral/earth-jumper copper bar to comply with local codes and regulations.

accommodate varying site requirements.
To connect an external battery cabinet:
1.
Locate the DC circuit breaker on the front bottom of the EBC frame behind the bottom two
bezels, and verify that the circuit breaker is open.
2. Attach the EBC cable ground wire to either the ground-wire connection points labeled "5" or "6"
in Figure 3.25 on the facing page or Figure 3.26 on page 46 (Depending on whether or not
the UPS has a transformer).
•
Choose the connection point with the easiest access and that applies the least amount of
stress to the ground wire after the DC connector is installed.
•
Connect one ground wire to the UPS and the other to the EBC.
IMPORTANT! Do not continue with installation until the ground wires are firmly installed.
3. After the frame grounds are properly bonded together, connect one end of the battery power
connector to the external battery connector on the rear of the UPS frame as shown in Figure
3.25 on the facing page or Figure 3.26 on page 46, depending on your system.
4. Connect the other end to the closest corresponding port on the rear of the EBC frame.
5. Install and tighten the grounding screw on the battery cable assembly, on both the UPS and
EBC ends.
This screw also secures the cable assembly to the frames to prevent accidental disconnection.

6. For new systems that included an EBC, the EBC communication card should already be
installed in the UPS frame (IntelliSlot Port #3, typically).
•
If it is not installed, obtain the EBC communication card and insert it into any open
IntelliSlot port (preferably Port #3).
•
Connect the provided EBC communication cable to the UPS and EBC as shown in Figure
3.25 below or Figure 3.26 on the next page, depending on your system.
7. Check the EBC DIP-switch settings on the top rear of each EBC frame, and verify that they are
set correctly according to Table 3.12 on page 47.
7. Close the EBC DC circuit breaker and replace the bezels back onto the EBC.
WARNING! Risk of hazardous voltage between UPS frames. Can cause damage to equipment,
injury and death. Failure to open the EBC DC circuit breaker before connecting or
disconnecting the battery cable between the UPS and EBC frames can result in hazardous

6.3.1 Removing Power, Battery and Charger Modules
WARNING! Risk of heavy unit falling over. Can cause equipment damage, injury or death. Read
all of the instructions before attempting to move the unit, lift it, remove packaging or prepare
the unit for installation. The UPS presents a tipping hazard. Do not remove more than one
module at a time. Failure to do so may cause unit to tip over and cause serious injury.
1.
Remove bezel cover to locate the faulty module. The yellow fault LED is illuminated on the
faulty module.
NOTE: When removing bezels from a transformer-based UPS, note which have filters and replace them
accordingly. Bezels from the modules have air filters. There are no filters on the bottom three
transformer bezels. The transformer has a separate air filter.
NOTE: If your system does not contain a redundant module, you may need to manually place the UPS
into manual bypass before removing modules to avoid accidental loss of output power for the
connected equipment.
