• Tools Required: Electric drill; #25 (0.1495”) drill bit; screwdriver or nut driver (as required
for customer supplied mounting screws); and four #8-32 self-tapping machine screws.
• The ELECTRA-flo G5 transmitter can be mounted in any position provided it is secured
using all four mounting holes.
• Reasonable consideration should be given to clearances for electrical connections.
• Once a suitable location is found, use the transmitter as a template to mark the centers of
the four mounting holes.
• Drill four pilot holes at the marked locations. With the unit in position, install the four #8-
32 screws.
3.5 POWER and SIGNAL CONNECTIONS
The REMOVABLE* terminal strips for power and signal are located in the lower portion of the
transmitter and are accessible by opening the hinged cover. (See figure on next page for the exact
location of the terminal strips.) Two conduit openings are provided in the bottom of the transmitter
enclosure; one for power and one for signal wiring.
Recommended wire gauge (14 AWG is the maximum wire gauge - no more than two wires
recommended per terminal):
Power wire = 14 AWG to 18 AWG
Signal wire = 14 AWG to 22 AWG
* To aid in the wiring of both power and signal wires, J1-J4 are removable by pulling the terminal
strip straight up and off the circuit board. Once wiring has been completed, replace the terminal
strip by aligning it with the receptacle and inserting firmly.

IMPORTANT NOTE
The ELECTRA-flo G5 transmitter terminal connections for power and signal wire are
labeled on the board for installation convenience. Power wiring is located at terminal strip
J4. Signal wiring is located at terminal strips J1-J3.
