exists which will result in personal injury if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid possible injury or death.
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, can result in death
or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor
or moderate injury.

RELATIVE HUMIDITY (% RH)
RELATIVE HUMIDITY (%
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring. In addition, the room temperature and humidity combination should conform
to the environmental operating envelope as defined in the following graphics.
AMBIENT TEMPERATURE (°F)
Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended for
ceiling and wall applications. Apply rubber- or plastic-based paints to concrete walls and floors.
Insulate the room to minimize the influence of exterior heat loads. Reduce fresh air to the minimum required by
local and national codes and regulations. Fresh air imposes extreme load variation on the cooling equipment
from summer to winter and causes increased system operating costs.
Air distribution
The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and
discharging cooled air into a cold aisle.
NOTE: The equipment is designed for free air discharge or for use with the Rack Air Containment System or
Hot Aisle Containment System. The equipment is not intended to be connected to a duct system.
Incoming power supply requirements
WARNING
ELECTRICAL HAZARD
• Electrical service must conform to local and national electrical codes and regulations.
• The equipment must be grounded.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
InRow RC Installation Manual

Automatic Transfer Switch (ATS): The function of the ATS is to transfer the
load from feed A to feed B if the power is lost on feed A.
na2252a
• Feed A (Primary Power Feed) supplies power to all functions in the
equipment.
• Feed B (Redundant Power Feed) supplies power to all functions in the

Service access
An area of minimum 900 mm (36 in.) of clear floor space in front of and behind the equipment is recommended
for servicing (208V equipment), or 1067 mm (42 in.) for servicing 400V and 480V equipment. All required
normal maintenance can be performed from the front or rear of the equipment while in the row.
An area of minimum 1200 mm (48 in.) of clear floor space in front of or behind the equipment is recommended
to roll the equipment out of a row.
NOTE: Check local and national codes and regulations for further service access requirements.

Leveling the Equipment
CAUTION
SHOCK HAZARD
After reinstalling the front door, reconnect the ground wire and other wire connections.
Failure to follow these instructions can result in injury or equipment damage.
NOTE: The leveling feet at the corners of the equipment provide a stable base if the floor is uneven, but they
cannot compensate for a badly sloped surface.
1. Remove the front and rear doors. See “Removing the front and rear doors” on page 21.
NOTE: Before removing the front door, unplug the ground wires and any other wire connections that
may interfere with the removal of the doors.
2. For each leveling foot, insert a Phillips PH2 or slotted
screwdriver into the screw above the leveling foot. Turn
the screw to the right to extend the leveling foot until it
makes firm contact with the floor.

Condensate pump
na2345a
The pump is factory-wired and piped
internally to the condensate drain pan.
The pump can move liquid a maximum of
18 m (60 ft), which may include a
maximum lift of 3.5 m (11.5 ft) at a flow
rate of 87 l/hr (23 gph). For example, if
your lift is 3 m (10 ft), you will have 15 m
(50 ft) of usable run remaining. The pump
uses an on-board condensate high level
float switch wired into the equipment for
alarm capabilities.
CONNECTION

CONNECTION
THROUGH BOTTOM
The condensate drain line can be
connected through either the top or the bottom of the equipment using factory-installed male
quick connectors and tubing approved by local building codes that will allow the drain line
connector to be moved approximately 25 mm (1 in.) away from the equipment. This facilitates
removing the equipment from a row. Female quick connectors and reduction fittings are
supplied with the equipment. Connect the fittings as shown, then connect the drain line quick

The following electrical connections are required in the field:
• Controls (user interface, Network Management Card)
• Communication (A-Link, Building Management System)
• Power
NOTE: All electrical connections must be in accordance with local and national codes and regulations.
See the equipment nameplate for voltage and current requirements.
All low-voltage connections, including data and control connections, must be made with properly insulated
wires. Low-voltage wiring must be insulated based on the wiring with which it is routed. Wiring does not require
300-V insulation if it is separated from line voltage wiring. However, it will need 600-V insulation if it is wired in
the same cable tray as 480-VAC wiring.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Potentially dangerous and lethal voltages exist within this unit. More than one disconnect
switch may be required to energize or de-energize this equipment. Observe all cautions
and warnings. Failure to do so could result in serious injury or death. Only qualified
service and maintenance personnel may work on this equipment.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work
practices. See NFPA 70E or CSA Z462.
