4. Cabling the Interface
i)
Gently pry the clear locking
tab outside of the yellow jacket
on both ends of the cable as
shown.
Ensure yellow jacket has not moved out of
position when inserting to the Midas
or LON
®
Module connectors (clear tab is to rest on top of
the yellow jacket bubble).
Caution: Do not over-extend the tab as damage
may result.
ii)
Bend the cable into 1½ loops
as shown. The two connectors
should be approximately 3 cm
apart. This is to reduce torque
on the installed connector.
iii)
Plug the cable into the Midas
and the Interface as shown.
Loosen the black plastic cable
locker on the bottom of the
Midas. Slide this clamp under
the cable locking tab to
prevent the tab from being
depressed. Tighten the locker.
