InRow RC Installation34
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).
