OTHER CHILLER PANEL INSTALLATION
For all other applications, the SC-EQ Comm Card in-
cludes an optional enclosure. The optional enclosure
does not include communication cables due to the vari-
ety of types and lengths that may be required.
Never install the SC-EQ Comm Card outside the con-
fines of a building unless within another enclosure
rated IP 65/NEMA 4x or higher.
The SC-EQ Comm Card can be mounted as a stand-
alone enclosure either on the outside surface of the
chiller Micro Panel (close coupled), or on a smooth
surface within close proximity of the chiller panel en-
closure.
For mounting on a Micro Panel, the line voltage power
is supplied by a power source in the Micro Panel.
IMPORTANT: Make sure that the cover is securely
fastened to the enclosure and the internal ground wire
is attached before placing the SC-EQ in operation.
These steps help to minimize Radio Frequency Inter-
ference (RFI) from being generated and picked up.
