Mounting the ESRS Unit
Use the ESRS unit 4 mounting screw holes (screw not included) to mount the
unit. Connect the Display Panel to the ESRS unit via the RJ45 socket using the
CAT-5 cable. Longer CAT-
5 cables (10’, 20’, 50’, 100’
and
150’
) are available
to increase the distance between the ESRS and the Display Panel. Refer to
the Display Panel installation manual for the correct installation instruction.

ESRS Unit Wiring Installation
Use a minimum of 16 American Wire Gauge (AWG) (SAE J3788 or J1128)
according to American Boat and Yacht Council (ABYC) [or equivalent
international standard] marine grade wire to connect all devices and power
to the ESRS. Connect the wire to the ESRS
unit by pushing a 1/8” flathead
screwdriver into the square opening on the top of the terminal block. This
opens the spring cage allowing a stripped wire to be installed into the round
hole on the connector. See Figure 1.
