Room Preparation
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring.
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. Use the minimum required amount of
fresh air for make up to comply with local and national codes and regulations. Fresh air imposes extreme
load variation on the cooling equipment from summer to winter and causes increased operating costs.
The equipment is designed as a sensible cooling air conditioning unit for in-row use in data centers. The
equipment does not have humidification or dehumidification control. Room humidity must be within
acceptable operating conditions before starting equipment. If operated in spaces where the humidity
is in the unacceptable operating conditions section of the Operating Guidelines chart (see the InRow RC
Operation and Maintenance manual) the equipment condenses excess water vapor from the air. This will
exceed the pumping capacity of the condensate pump, causing the equipment to send an alarm and shut
down to avoid overflowing the condensate pan. The condensate pump runs until the fluid level in the pan
is reduced, and the alarm is automatically reset. The equipment self-regulates in this manner until normal
operating conditions are present.
Note: The InRow RC is not intended to be used in an occupied office environment, due to
potentially high noise levels during peak loads. Install the InRow RC in a computer room
where people are normally present only for maintenance.
Incoming power supply requirements
See the electrical rating label on the equipment to determine the maximum possible current draw of the
equipment. Provide either a single outlet circuit or a Power Distribution Unit (PDU) with sufficient
capacity to handle all loads. Do not plug two InRow RC units into the same branch circuit or PDU.
The equipment must be grounded. Electrical service must conform to national and local electrical codes
and regulations.

Feeds A and B. The equipment is capable of receiving power through one of two separate feeds, feed
A or feed B. Use the display interface to configure the unit to receive power through feed A, feed B, or
both). If connected, feed B is the primary power input to the equipment by default; feed A is the backup
power input. The equipment receives power through feed B regardless of whether feed A is receiving
power. If power is removed from feed B, feed A takes over and supplies power to the equipment (if feed
A is connected). Connect the feed A and feed B cables to individual, breaker-controlled branch circuits
or to PDUs backed by separate Uninterruptible Power Supplies (UPS).
Note: Feed A and feed B must not use the same branch circuit, PDU, or UPS.
For more information on configuring power input feeds, see the InRow RC Operation and
Maintenance manual.

Field-supplied voltage
(12/24 Vdc or Vac)
A relay internal to the user interface is typically controlled by a user-defined alarm (malfunctioning fans,
for example). Before an alarm is detected, the voltage on the COM terminal is routed to the NC terminal.
When the alarm is activated, the relay is energized, causing the voltage on the COM terminal to be
routed to the NO terminal. The NO and NC terminals may be connected to remote indicator lights, a
warning buzzer, or another device to alert an operator to the presence of an alarm condition.
A remote disconnect switch may be connected to the shutdown inputs.
Leak detector port
Rope water detector (AP9325). Up to four optional rope water
detectors can be installed in series. The rope water detector
connects to the RJ-45 leak detector port located at the top of the
interface box.

sensor
The remote temperature sensor monitors the room temperature,
monitoring the environment surrounding the cooling equipment to
ensure that the conditioned air is cooling the area.
Note: The remote temperature
sensor comes coiled inside the
equipment as shown, and must
be mounted as follows, or the
equipment will not operate
properly.
gen0744a
Install the temperature sensor.
1. Route the rack temperature sensor through the hole in
either the top or bottom of the unit.
2. Route the sensor through either the top or the bottom
of the adjacent server rack.
3. Secure the temperature sensor cable to the front door
of the adjacent server rack at multiple locations using
the provided wire clips as shown. See “Installation
kit” on page 3.
The sensors must be installed where lack of sufficient
cooling air is most likely. The optimum position of the
rack temperature sensors will vary from installation to
installation, but should be located in the airflow to
allow accurate readings.
Servers most likely to have insufficient air or inadequately cooled air due to the recirculation of
hot air from the hot aisle include:
a. Servers positioned at the top of a rack.
b. Servers positioned at any height in the last rack at an open end of a row.
c. Servers positioned behind flow-impairing obstacles such as building elements.
d. Servers positioned in a bank of high-density racks.
e. Servers positioned next to racks with Air Removal Units (ARU).
f. Servers positioned very far from the equipment.
g. Servers positioned very close to the equipment.
