2 INTRODUCTION

The SmartRow DCR is an integrated component of the SmartRow™offering from Vertiv™. The system
includes a closed-loop, integrated cooling system and fire suppression. Assembly is a matter of
connecting the plenums and cabinets, then making electrical and piping connections.

The SmartRow DCR is available in three basic cooling configurations:

• 20-kW (N) Configuration—3- to 6-rack system capable of removing up to 20kW of heat (single
LiebertPDX/PCW).

• 20-kW (N+1) Configuration—3- to 6-rack system capable of removing up to 20kW of heat
(redundant LiebertPDX/PCW).

• 36-kW (N) Configuration—5- to 10-rack system capable of removing up to 36kW of heat (dual
LiebertPDX/PCWs).

Each configuration has different requirements and recommendations for setup and operation. Those
requirements are integral to effective operation of a SmartRow DCR.

The SmartRow DCR must be installed in an indoor, climate-controlled environment. The unit will not
protect electronic equipment if it is installed in an environment subject to extreme temperatures or
humidity.

This manual is to be used in conjunction with existing Vertiv™ product manuals for each component and
site-specific documentation and drawings. User and installation manuals ship with the equipment and are
also available at http://www.VertivCo.com/en-us/support/.

2.1 Operational Overview

The SmartRow DCR is an enclosed system to house and cool electronic equipment. The DCR racks house
the critical IT equipment, optional Rack PDUs and optional rack-mounted UPS units.

Cooling air is supplied by an integral Liebert PDX/PCW and conveyed to the racks with bottom plenums.
Heated exhaust air from the racks returns to the Liebert PDX/PCW through the top plenums. An
emergency fan system is included to exhaust air in the event of excessive internal temperature or a
primary cooling failure.

The DCR Control Panel and Fire Suppression System module contains the fire detection and suppression
system, fire strobe light and audible horn, the power/fire control interface, fire-suppression-system abort
and manual-release switches, emergency fan-reset controls, and the load-distribution center. The
fire-detection system uses a smoke detector to monitor the air in the SmartRow DCR for evidence of
combustion. If the smoke detector mounted in the return air plenum senses combustion products, the
system control activates audible and visual alarms and releases a fire-suppression agent (see Figure 7.1
on page61). The load-distribution center distributes power to powered loads inside the SmartRow DCR.

2.2 DCR Control Panel andFire-suppressionSystemCommissioningandTraining

A local qualified service representative will commission and arm the DCR Control Panel and Fire
Suppression System after the SmartRow DCR is fully installed and operational. The representative will
conduct training on the system during the same visit. The commissioning, arming and training cannot be
performed before all items in Cooling and Power Component Installation Checklist on page67, and Fire

Suppression System Installation Checklist on page68, have been completed.

3 PREPARATION

The application and installation location should be determined and prepared before the SmartRow DCR is
delivered. Proper planning will permit installing the required power and coolant connections and ensuring
proper clearances. The installation location must have:

• An indoor, climate-controlled environment free from moisture, flammable liquids, gases, and
corrosive substances.

• An environment that is maintained year-round at an ambient temperature between 35°F and
85°F (1.6°C to 29°C) and a relative humidity between 50°F and 85°F dry bulb and less than
60°F dew point.

• Sufficient height and clearance from ceilings, walls, fixtures and overhead sprinkler nozzles for
the SmartRow DCR, including its emergency fans

NOTE: The SmartRow DCR must be installed on a flat, level surface to maintain proper spacing and
provide tight seals. Leaving gaps in the field-applied gaskets will reduce cooling efficiency, increase
energy use and adversely affect fire-suppression system operation.

• Heat rejection coolant supply for the Liebert PDX/PCW

• Input power sufficient for:

• Each Liebert PDX/PCW—one or two units; each requires a separate input power feed.

• DCR Control Panel and Fire Suppression System, Emergency Fans and powered
equipment installed in the DCR racks

For details about any component’s requirements, refer to that unit’s user manual. The Liebert PDX/PCW
installation manual is SL-19800; Liebert iCOM™ user manual is SL-18835. These are delivered with the
unit and are available at http://www.VertivCo.com/en-us/support/.

damage is noted, notify your local Vertiv™ representative and the carrier immediately.

3.3 Unloading the SmartRow DCR

Before unloading the SmartRow DCR, refer to the manual for each component, particularly the Liebert
PDX/PCW and DCR Racks. These manuals are shipped with the SmartRow DCR and are available at
http://www.VertivCo.com/en-us/support/.

Vertiv | SmartRow DCR Installer/User Guide | 13

Read these manuals thoroughly. They include handling instructions and safety notices that must be
followed when unpacking, installing, operating and maintaining the SmartRow DCR.

Adhere to all warnings, cautions and installation, operating and safety instructions on the units and in
their manuals. Only properly trained and qualified personnel should move, install, operate or service this
equipment.

3.4 Required Set-up Tools and Equipment

The following tools are needed to set up a SmartRow DCR:

• 3/4-in. (19-mm) open end wrench or socket

• Ratchet to fit sockets

• Phillips-head screwdriver

• Flat-blade screwdriver

• Forklift or pallet jacks

• Scissors or knife

• Carpenter’s level, 3-ft long or longer

3.5 Heat Load Guidelines

Notice

Risk of exceeding cooling capability. Can cause equipment damage.

A SmartRow DCR 20-kW (N) configuration (one PDX/PCW cooling unit) or 20-kW (N+1)
configuration (two PDX/PCW cooling units) is capable of removing 20 kW of heat. A SmartRow
DCR 36-kW (N) configuration (two PDX/PCW cooling units) can remove 36kW of heat.
Exceeding that heat load limit, such as by overloading the DCR racks, can cause equipment in
the cabinets to overheat, resulting in equipment damage and voiding warranties.

Refer to the values in Table 3.2 below. The total system capacity and heat loads per cabinet must fall
withing these ranges. We recommend that higher-density loads be located in the center of the SmartRow
configuration. This avoids the need to manually adjust the air dampers when thermal-management units
switch in 2-unit configurations.

3. Repeat steps 1and 2 for the remaining dampers.

4. The damper slides must be opened varying amounts to provide adequate cooling for each
DCR Rack:

NOTE: The cooling air flow required by the equipment in a DCR Rack will vary according to several
factors, especially the distance from the Liebert PDX/PCW and each rack’s heat load. Do not obstruct
back draft dampers in the bottom plenum. We recommend running all rack PDU cables through the top
plenum.

a. After the SmartRow DCR is operational and the heat loads have time to equalize, check

the temperature in each DCR Rack with the racks’ doors closed via the 2Tsensors
connected to the CANbus port on the Liebert iCOM.

• If the 2T sensor reading of a rack is lower than the average leaving air temperature of the
other racks, close the inlet damper slightly to reduce cooling air flow.

• If the 2T sensor reading of a rack is higher than the average leaving air temperature of
the other racks, open the inlet damper slightly to increase cooling air flow.

b. Reposition the air-flow adjustment dampers to equalize the cooling in each rack as

needed, referring to Figure 4.27 on the next page:

• Loosen the wing nuts.

• Move the damper to the position you want.

• Tighten the wing nuts to make sure the damper doesn’t move during operation.

c. Repeat steps a and b until the system is equalized.

4.13 Air/Ventilation Management

Free rack space in the DCR racks must be blocked with blanking panels. Blocking the open space helps
optimize system cooling performance by minimizing short cycling of conditioned air.

Heat loads should be balanced as well as possible among the cabinets. This can be done by distributing
equipment evenly among the cabinets to avoid excessive heat concentration. Refer to Table 3.2 on
page14 for details.

4.13.1 Ventilation Requirements

• The maximum room temperature for a SmartRow DCR is 85°F (29°C).

• The air-supply inlet temperature to the room should match the output capacity of the
emergency fans.

• If the room is sealed, the air inlet opening size from the building should be 1.5 ft2(0.14m2) per
rack.

• If the ceiling space is not open to the rest of the building, a damper or grille of 1.5 ft2 (0.14m2)
per rack will be required.

4.13.2 Emergency-fan Notes

The emergency-fan assembly for each rack will move nominally 1160cfm (548 l/s) of air and are powered
from the Control Panel and Fire Suppression System through a factory-installed L5-20 receptacle on top
of the Top Plenum-PDX/PCW.

If the SmartRow DCR is installed in a dedicated room and airflow inlet and outlet openings to the room are
not provided, the emergency fans will remove cabinet heat for only a short time.

4.14 Cable Management

The SmartRow DCR includes factory-suppled cable-management accessories throughout the system,
taking advantage of industry best practices. Follow these cable-management guidelines to help ensure
optimal performance of your system.

4.14.1 Prepare for Cable Management

5 POWER CONNECTIONS

5.1 Power Connections to Liebert PDX/PCW

Provide input power to the Liebert PDX/PCW on its own dedicated circuit based on the specific Liebert
PDX/PCW configuration requirements. Input power to the Liebert PDX/PCW must not be connected
through the 225A 3PH or 125A 1PH load center in the DCR Control Panel and Fire Suppression System.
Refer to the Liebert PDX/PCW user manual that shipped with the unit and is available at
http://www.VertivCo.com/en-us/support/.

For electrical and piping connections, the Liebert PDX/PCW can be top-fed, bottom-fed or a combination
of the two. Connections are made through the knockouts in the bottom of the Liebert PDX/PCW electrical
panel/box. For top access, power wiring is routed through the Liebert PDX/PCW top piping chase.

NOTICE

Risk of improper power input. Can cause equipment damage or degraded cooling.

The Liebert PDX/PCW must be powered separately by a dedicated circuit. Power must not be
supplied from the 225A 3PH or 125A 1PH panel, in part because of potential electrical noise
problems.

5.2 Input Power Wiring Alternatives to DCR Control Panel andFireSuppression
System and Rack Equipment

The load-distribution center located inside the DCR Control Panel and Fire Suppression System requires
connection to either a 120/208VAC, 3-phase, 5-wire connection, or a 120/208VAC, 1-Phase, 4-wire
connection depending on the phase of the load-distribution center selected.

Two 120VAC, 15A branch breakers are supplied for:

• DCR Control Logic/Emergency Ventilation Fans

• Fire Suppression System

The user must supply branch breakers, whips and wiring for all rack equipment, including optional rack
PDUs, rack UPSs and general connectivity.

The SmartRow DCR Fire Suppression system and the Control-logic/Emergency-fan circuits must be
connected to an on-line, double-conversion UPS power source to ensure that the Fire-Suppression
system, Control Logic and Emergency ventilation fans do not lose power in the event of any type of power
interruption. The remote emergency-power-off (REPO) switch for the UPS may be a normally-open (N/O)
or normally-closed (N/C).

NOTE: The connection requirements to the SmartRow DCR for each system is different. UPS systems
with a N/O REPO switch must tie-in to terminals 25 & 26A, and the jumper between terminals 21 and 22
must be removed. UPS systems with a N/C REPO switch must tie in to terminals 25 & 26
(See the figure "SmartRow DCR control logic" in Technical-installation Illustrations on page81). It is
criticalthat this UPS is connected to the system correctly.

Vertiv | SmartRow DCR Installer/User Guide | 53

The remaining UPS systems that are connected to loads within the SmartRow DCR system must be N/C
systems. Please refer to the figure "SmartRow DCR control logic" in Technical-installation Illustrations on
page81,” for further details.

NOTE: To determine if an electrical disconnect is required to be installed in conjunction with the use of
the SmartRow DCR, consult local codes and agency requirements.

6 LIEBERT ICOM™ CONTROLS SET-UP

The Liebert iCOM provides control of the Liebert PDX/PCW and monitoring of conditions in the DCR
racks. If more than one SmartRow DCR is installed, the Liebert iCOM’s may be networked so that each can
be monitored or controlled from a single location.

Field-wiring is required for the Liebert iCOM, even if it is part of a stand-alone unit, as in a single SmartRow
DCR. Refer to the Liebert PDX/PCW installation manual, SL-19800, or to the Liebert iCOM user manual,
SL-18835. The manuals are available at http://www.VertivCo.com/en-us/support/.

The Liebert PDX/PCW with Liebert iCOM has Liebert IntelliSlot™ slots for use with optional
communication card:

• IntelliSlot UNITY-DP card

Each card employs the Vertiv™ Protocol to monitor and manage a wide range of operating parameters,
alarms, and notifications. The cards communicate with Vertiv™ software tools & services, including Trellis®,
Liebert SiteScan Web™ and Liebert Nform®. Visit www.VertivCo.com for the latest supported protocols.

The Liebert iCOM must be configured as stated in this section for the SmartRow DCR to operate properly.
These instructions are applicable to SmartRow DCR systems with one or two Liebert PDX/PCW units and
all cooling-system types (air-cooled, water/glycol and chilled water). These configurations must be made
on each cooling unit, even if the units are networked, because not all settings are shared. These Settings
are factory set, but the this documentation illustrates how to set them if anything were changed or was
malfunctioning for some reason.

6.1 iCOM Installation Prerequisites

• System fully assembled according to this document.

• 2T temperature sensors installed on the front (cold side) of each rack and the supply air
temperature sensor(s) properly located in the supply air stream.

• If the SmartRow DCR has two Liebert PDX/PCW cooling units, verify that they are connected
and communicating to each other via an Ethernet switch.

6.2 Liebert iCOM Setup for all SmartRow DCR Types

You will need to enter the Level 2 iCOM control password, 5010, to change parameters.

Make these settings in the Liebert iCOM Service Menu > Setpoints:

• S102 Temperature Control Sensor: Remote Sensor

• S103 Temperature Setpoint Act / Set: 65°F (this can be adjusted per customer preference)

• S104 Temperature Control Type: PI

• S106 Temp Proportional / Integral: 25°F/ 5 min.

NOTE: After the IT equipment is loaded and operational, if the SmartRow DCR system cooling capacity
is responding too slowly to heat load changes, decrease the Integral time, which dampens Liebert
iCOM’s rate of change). We recommend that you adjust the Integral time before adjusting the
Proportional setting.

• S108 AutoSet Enable: No

• S109 Temperature Deadband: 2°F

• S110 Supply Limit Enabled/Setpoint: No

Vertiv | SmartRow DCR Installer/User Guide | 55

6.2.1 Set Fixed Fan Speed to Factory-approved Level

To set the fan control to a fixed fan speed at the factory-approved level, select Service Menu > Fanspeed
Control >

• S146 Fan Control Sensor: Manual

• S153 - Fanspeed Dehum/No Power: 100/100

6.2.2 Prevent False High- and Low-Temperature Alarms

The Liebert iCOM is set at the factory for open rooms. The high number of air exchanges in the SmartRow
DCR may cause false alarms. These may be prevented by delaying the sensor triggers.

To delay the sensor triggers, make these settings in the iCOM Service Menu > Set Alarms:

• S219 REM Sensor Alarms / Init Delay: Com Set: 180sec
(Com Set means “common setpoint” for delaying all sensors.)

• S220 High and Low Remote Temperature Setpoints: 90°F / 55°F
(for remote 2T rack sensors)

NOTE: The system must use V4 IS cards (Unity) to report temperature alarms remotely.

6.2.3 Prevent Emergency Fan Activation by Warnings

To prevent warnings from activating the emergency fans, make this setting in the iCOM Service Menu >
Set Alarms:

S232: Warning Activates Alarm Relay: NO

Once the critical threshold is surpassed, the iCOM would generate an alarm and activate the emergency
fans.

NOTE: If a Warning occurs, it is recorded in the Event Log.

6.2.4 Control Cooling Calculation byRemote2TRackTemperatureSensor Readings

The Liebert iCOM automatically reverts to using the supply air temperature sensor in the base plenum if
it loses communication with the remote rack sensors. The return air temperature sensor should never be
used as a controlling sensor in the SmartRow DCR.

Make these settings in the iCOM Service Menu > Remote Sensors:

• Remote Sensors: Verify that all remote sensors installed on the front (cold) side of the racks are
set to “Control” not “Reference.”

• SB02: Max (This takes the average or maximum of the two temperature probes per 2T).

• SB03: Max (This takes the average or maximum of all the 2T sensor readings).

NOTE: Verify that the 2T temperature sensors are in an active air stream. Do not place the probes in
front of blanking plates. Additional 2T temperature sensors can be installed in the SmartRow DCR for
monitoring, such as determining the temperature in the rear of the racks. These sensors must be setup
as “Reference.”

These settings apply to a SmartRow DCR that has two Liebert PDX/PCWs, one operating and one in
standby mode.

Before making these changes, complete the adjustments in Liebert iCOM Setup for all SmartRow DCR

Types on page55.

These settings allow the cooling units to share the remote 2T temperature sensor data when the cooling
units are operating or on standby. This ensures that the temperature readings from all racks are factored
into the cooling capacity calculation (CFC: Call for Cooling). Additionally, if the heat load temporarily
exceeds the capacity of the SmartRow DCR’s operating cooling unit, the standby unit will be
automatically started to assist. When one cooling unit can again maintain the load the second unit will
return to standby mode (cooling and fans Off).

1. Make these settings in the iCOM Service Menu > System / Network Setup:

• S803 Teamwork Mode: 1

• S804 Teamwork is based on: Maximum

NOTE: The controlling temperature sensor (S102) must be properly selected (see Liebert iCOM Setup

for all SmartRow DCR Types on page55) before setting the Teamwork Mode, followed by setting

Standby and Cascade modes.

2. Make these settings in the iCOM Service Menu > Standby Settings / Lead-Lag:

• S502 Number of Standby Units: 1

• S503 Rotation Frequency: Every WED (schedule for convenient day)

• S504 Rotate at: 09:00 (schedule at convenient time)

• S505 Rotate by: 1

NOTE: We recommend scheduling the cooling system rotation to occur at a time the person in charge
of the SmartRow DCR operation is present.

• S515 Cascade Units: Cooling

• S516 Cascaded Units Delay: 3 min

• S517 Cascaded Units Quick Start: 0 min

Vertiv | SmartRow DCR Installer/User Guide | 58

6.4.1 Prevent High-temperature Threshold fromStartingAllLiebertPDX/PCWs

The high-temperature threshold, when enabled, will prompt the Liebert iCOM to start all cooling units.
The function is intended to prevent high temperatures in the SmartRow DCR. However, when the second
Liebert PDX/PCWis activated by this parameter, the cooling unit will remain On until you manually
acknowledge it’s activation by pressing the horn button on the Liebert iCOM or over remote monitoring.

To prevent the high-temperature threshold from starting the second Liebert PDX/PCW, go to the Service
Menu > Standby Lead-Lag > S513: Start all Standby units by HT. Change the setting to “NO.”

NOTE: While this setting is disabled, the combination of Teamwork Mode and Cascade settings will
achieve the same result (see Additional Settings for 20-kW, 3-to6-rackSystems—N+1cooling Only

(2PDX/PCWs-onecoolinguniton,oneinstandby) on the previous page). During thermal overload

scenarios the redundant Liebert PDX/PCW will be activated to provide supplemental cooling and
automatically reset when no longer needed.

NOTE: The default high temperature threshold is 80°F. The user may reset this threshold once the
temperature drops 4°F below the setpoint. This threshold operates only off the return air temperature
sensor.

6.4.2 Prevent False High-humidity Alarms

Delaying the humidity alarm will prevent false high-humidity alarms during a rotation of cooling units. The
humidity sensor in the standby Liebert PDX/PCW will report a false high humidity reading because it is
briefly not in an active air stream.

To delay the alarm, make this setting change in
Service Menu > Set Alarms (Page 4) > S241 High humidity: 120 second

The default delay is 30 seconds. The maximum is 9,999 seconds.

6.5 Additional Settings for 36-kW, 5-to10-rackSystems—NCooling Only
(2PDX/PCWs - both units on)

These settings apply to a SmartRow DCR that has two Liebert PDX/PCWs operating at a time. The
system’s cooling capacity is 36 kW.

Before making these changes, complete the adjustments in Liebert iCOM Setup for all SmartRow DCR

Types on page55.

6.5.1 Ensure Even Airflow to all Racks During Low Heat Load

The compressor in the secondary Liebert PDX/PCW may shut off if the heat load is low. The intent of the
setting is to avoid over-cooling and undesired dehumidification. This change rotates the designation of
“primary cooling unit” between the cooling units to help balance compressor run hours. If the fan in the
secondary PDX/PCW unit were to shut-off, some racks would experience hot spots. These settings also
ensure that the temperature readings from all racks are factored into the cooling capacity calculation

7 DCR CONTROL PANEL AND FIRE SUPPRESSION SYSTEM

The SmartRow DCR must be installed in compliance with all applicable national, state and local fire codes.
An emergency power off (EPO) switch is provided as one means of meeting regulations. Additional field­supplied connections to the system may be required, depending on the applicable regulations, the
equipment configuration and the user’s operational preference.

The DCR Control Panel and Fire Suppression System has been fully tested and certified at the factory.

The DCR Control Panel and Fire Suppression System is shipped with wiring that, if required by local fire
code, must be field-connected to the shutdown circuits of the Liebert PDX/PCW and any connected UPS
systems.

Under NFPA regulations, systems protected by a clean fire-suppression agent can be left with the UPS
and HVAC systems operational at the discretion of the owner and local fire officials.

The DCR Control Panel and Fire Suppression System should be field-connected as a separate zone to the
building fire detection and alarm system.

If the SmartRow DCR is installed in a dedicated room, an additional strobe and horn may be installed at
the entrance to the room. Contact your local authorized service representative if required.

7.2 Recovering from EPO Circuit Activation

In the event that the EPO circuit is activated by the local EPO button on the SmartRow DCR or by a field­supplied REPO button and the system is shut down, the following steps must be taken to recover:

1. If a Shunt-Trip Main Circuit Breaker is being used, reset the Shunt-Trip Main Circuit Breaker.

2. Disengage the EPO circuit:

NOTE: You must reset the EPO or REPO button that activated the circuit to reset the circuit. Pressing a
button that did not originally trigger the circuit will not reset the circuit.

a. If the local EPO button on the DCR activated the circuit:

• For a Non-latching EPO button on the DCR: Push the EPO button to disengage the
circuit.

• For a Latching EPO button on the DCR: Pull the button back to disengage the circuit.

b. If a remote EPO (REPO) button activated the circuit, reset the REPO button that

activated the circuit using the reset function of the field-supplied button.

Once cleared, the thermal-management units in the SmartRow DCR automatically start via
their dedicated power supply.

3. Turn the Local Emergency Power Off Override Timer past the 1/2-hour position.

NOTE: If needed, you may turn the timer to a maximum of 2 hours. If time is running low, turn the timer
past the 1/2-hour mark again to continue the bypass.

Vertiv | SmartRow DCR Installer/User Guide | 64

4. Reset the UPS that powers the SmartRow DCR control circuit and fire-suppression control
circuit.

a. If the SmartRow DCR is powered by a stand-alone Liebert UPS, refer to the corresponding

procedure in the manual for the UPS to start-up the UPS. If it will not restart, put the UPS
in bypass and restart the remaining equipment. For assistance putting a Liebert 3-phase
UPS in bypass and for service support, call 800-543-2378. For a Liebert single-phase UPS,
call 800-222-5877, option #1.

b. If the SmartRow DCR controls, and emergency fans are connected to rack-mounted

UPSs, you must manually restart the UPS(s). Refer to the corresponding procedure in the
manual for the UPS to start-up the UPS.

The Fire-suppression System is protected from commercial power failures by an integrated battery and
battery charger. In the event of a commercial power failure, the fire-suppression system continues to
operate in idle mode from this battery for up to 48 hours. Upon restoration of commercial power, the
battery charger automatically recharges the battery to float state.

7.3 Recovering from a Fire Suppression System Activation

In the event of a fire suppression system activation, contact your local fire-suppression representative for
