InRow RC Installation Manual36
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.
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. If
the configuration is changed from top to bottom, switch the
wire already positioned in the connector J23 with the wire
labeled with a green and a white tie wrap. This wire is part of
the wire harness inside the electrical panel.
Communication connections
A-Link connections: The A-Link bus connection allows communication between cooling units. Only one
InRow RC needs to be defined through the display. The numbering of the other InRow RCs (up to a maximum
of twelve) will take place automatically.
To enable the equipment to work as a group, link the units using the supplied cables or CAT-5 cables with RJ-
45 connectors as shown. Terminators (120 Ohm, 1/4 W) must be inserted into the open A-Link ports at the first
and last InRow RC.
The maximum wire length for the entire group may not exceed 1000 m (3,280 ft).
