FloBoss 407 Instruction Manual
B-10
Rev 5/00
Connect the Remote MVS to a suitable earth ground per applicable codes and standards. Two means of
grounding are available on the unit: internal and external. To use the internal ground to meet U.S. and
Canadian requirements, connect to the ground terminal inside (a ground lead wire is supplied in the
MVS101R). To meet IEC and CENELEC requirements, use the external ground lug to connect to earth
ground.

Figure B-10. Signal Hook-Up for a Remote MVS Installation (MVS205 shown)
The FloBoss 407 allows up to four MVS devices to be connected on its communications bus in a multi-
drop connection scheme.
The address of each MVS must be set prior to final wiring of multiple
MVS devices.
For proper operation of multiple MVS devices, each MVS device must have a unique
address. Refer to Section B.5 for information on setting these addresses.
Once a unique address is set for each MVS in the multi-drop configuration, connect like terminals to
like. This means all the “A” terminals on the devices are electrically connected to the FloBoss 407 “A”
terminal and so on. The wiring can be done entirely from the FloBoss 407 with an individual cable to
each Remote MVS, or by wiring in parallel (daisy-chaining) though each Remote MVS.
Pay close attention to not reverse the power wires.
These connections should always be made with
power removed from the FloBoss 407. Double-check for proper orientation before applying power. If
the connections are reversed and power is applied, the MVS and the FloBoss 407 processor board may
be damaged.
