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.

Installation Removing Doors and Panels WARNING MOVING PARTS HAZARD • Do not open doors and panels if the equipment is operating Failure to follow these instructions can result in death, serious injury, or equipment damage. CAUTION UNPROTECTED PARTS Be careful when placing doors when removed from the equipment. Spring latches are easily damaged. Failure to follow these instructions can result in equipment damage.
Positioning the Equipment Service access na1565a An area of 1143 mm (45 in) of clear floor space in front and 914.4 mm (36 in) in back of the equipment is required for service. All required maintenance can be performed from the front or back of the equipment. Dimensions are shown in mm (in). Leveling The leveling feet provide a stable base if the floor is uneven, but cannot compensate for a badly sloped surface.
Stabilizing the Equipment Floor brackets To prevent the equipment from moving from its final location (if it is not joined with an enclosure), use the included bolt-down kit (AR7701). Follow the installation instructions included with the kit. Joining to enclosures NetShelter™ SX enclosure. Two joining brackets are installed on the front and rear of the equipment. Depending on how the holes on the joining brackets are used, you have the option of either 24-in or 600-mm spacing. 2.
Mechanical Connections Piping Note: Ensure coolant water quality complies with guidelines set forth in IB0125GB001. Water. Install shutoff Hot Aisle Containment valves for routine service and emergency isolation of the equipment. When a CDU is not used, you must install circuit setters to regulate the chilled water flow for each InRow RC air NetShelter conditioner. See “Piping Diagrams,” beginning on page 8. CDU NetShelter NetShelter Top piping examples shown PDU UPS Layout and piping considerations.
Connect piping See “Piping Diagrams,” beginning on page 8, for recommended valve, flexible adapter, and strainer installation locations. 1. Route all piping 1 to the InRow RC in compliance with all local and national codes. Note: Circuit setters are required to regulate the flow of chilled water to each piece of equipment. When a CDU is used in conjunction with the equipment, circuit setters are not required, as the CDU provides the flow-regulating function.
na1575a Condensate pump. The pump is factory-wired and piped internally to the lower condensate pan. The pump is capable of moving liquid a maximum of 15.2 m (50 ft), including a maximum lift of 4.9 m (16 ft). For example, if your lift is 3 m (10 ft), you have 12.2 m (40 ft) of usable run. The pump also uses an on-board condensate high level float switch, which is wired into the InRow RC alarm input for local and remote alarm capabilities.
Condensate pump drain installation. The condensate drain line is coiled inside the equipment, allowing you to route the condensate drain line for either top or bottom use. See the table “Piping and electrical access locations” on page 11 for more information. Use the provided grommets to properly secure and protect the condensate drain line. Top routing Note: Comply with all local codes when installing the condensate drain line to the proper drain system.
Filling and Purging When the equipment is properly piped, begin the filling process (top piping configuration shown). DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Turn off all power supplying this equipment before working on the equipment. Failure to follow these instructions will result in death or serious injury. 1. Open the 2-way supply valve and the 2-way bypass shutoff valve. 2. Using a 2.5-mm hex key, turn the flow control actuator to the fully open position.
3. Slightly open the top coil vent. 4. At the water supply, open the appropriate valves to begin letting water slowly enter the equipment. 5. At the equipment, close the top coil vent when water begins slowly flowing out of the vent. Top coil vent a. Open all valves (no greater than 76 l/m [20 gpm]), allowing the water supply to reach the highest possible flow to the equipment for 45 seconds. na1768a 6. At the water supply: b. Close the valves to a 3.8–11.4 l/m (1–3 GPM) flow for 60 seconds. c.
Electrical Connections The following electrical connections are required in the field: • Feeds A and B • A-Link • Network Management Card • Temperature sensor • Communication (building management system) See the electrical schematic (located on the lid of the electrical box) for all electrical connections. Make all electrical connections in accordance with national and local codes. See the InRow RC nameplate for voltage and current requirements.
Power connections Power cords may be routed through the top of the equipment (standard) or through the bottom (optional). Top wiring configuration Screws Top power cord entrance (standard). 1. Route power cords through the equipment to the top power cord access, as shown. 2. Push the power cords through the hole at the top power cord entrance. 3. Secure the plate to the underside of the equipment top with four Phillips screws (provided). Plate na1581a 4.

A-Link ports Note: All input and output connections should be wired as Class 2 circuits. Depending on the equipment configuration, additional control connections may be required for the A-Link remote communications through APC Network Management Card support or other equipmentmonitoring software. A special RJ-45 terminator is provided and must be installed if both A-Link ports are not otherwise used, as shown. Active flow controllers (AFC).

Form C alarm contacts and shutdown input Remote switch using internal power (24 Vdc shown) 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.
Temperature sensor Remote temperature sensor na2271a 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 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. Install the temperature sensor. 1.
