Condensate pump 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 onboard condensate high level float switch wired into the equipment for alarm capabilities.
Condensate overflow CAUTION WATER DAMAGE Failing to perform the following procedure may result in condensate pan overflow and possible damage to the data center. Failure to follow these instructions can result in equipment damage. na2538a Connect the equipment condensate overflow line to an external drain using the fittings, as shown.

See “Rack temperature sensors” on page 33. In and out connections for A-Link. The terminators supplied with the equipment must be plugged into the first A-link port and the final A-Link port for the group. 10/100 Base-T Network port. Connects the equipment to the network; Status and Link LEDs indicate network traffic.
Rack temperature sensors The rack temperature sensors control the unit airflow and ensure adequate supply of cooling air to the server racks in the data center. gen0744a The unit is supplied with three external rack temperature sensors. These sensors, along with wire clamps and wire clips, are included in the installation kit supplied with the unit in a separate box. Installing the rack temperature sensors 1.
Water outlet temperature sensors There are two water outlet temperature sensors, one for top connection and one for bottom connection. These sensors are wired to the main board on the electrical panel. Top connection: Wire with green tie wrap in J23 The unit is delivered with top connection as the default configuration, i.e., the wire with a green tie wrap is positioned in connector J23 (marked with green) on the main board.
Building Management System (BMS). The Modbus interface allows each InRow RC to communicate with the BMS. Use a three-wire cable to connect each InRow RC in turn. Wire a terminator resistor (150 Ohm, 1/4 W) into the Modbus master and the final InRow RC between Modbus D0 and Modbus D1. This terminator is included in the installation kit (see “Install kit inventory” on page 4). Each InRow RC has a three-wire Modbus terminal on the user interface. A connector with screw terminals is used to attach wiring.
Network port The Network port allows communication from the InRow RC to the network.
Power Connections Wiring configurations Incoming power may be supplied to the equipment using the supplied power cords (ACRC500 and ACRC502, top only). Incoming power may alternately be supplied by field wiring (top or bottom routing). CAUTION ELECTRICAL HAZARD Only a licensed electrician or APC-trained personnel may connect power cords to the equipment. All wiring must be done in compliance with local and national codes. Failure to follow these instructions can result in equipment damage.
