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.   

 

Figure 1 Terminal Block Slot 

 Properly ground all the Machinery connected to the ESRS unit.
