In the electronics head of the MVS101R (see Figure B-9), use the "+V" and "–V" terminals for power,
and the "A" and "B" terminals for signal wiring. Ensure power is turned off before connecting
wiring, and be sure correct polarity is observed; otherwise, equipment damage may occur.

Do not reverse polarity of the power wires (+ and -) while wiring the Remote MVS
units or circuits in the Remote MVS and elsewhere may be damaged. Double-check
for proper connections before applying power.
The terminals in the MVS205 head are labeled the same as the terminals on the MVS terminal block in
the FloBoss 407. Connect the FloBoss 407 and Remote MVS terminals one for one: A to A, B to B,
"+" to "+", and "-" to "-". Figure B-10 shows wiring for a typical Remote MVS installation.
