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.
Properly ground all the Machinery connected to the ESRS unit.
