tripped breakers may prove harmful to the
contents of the building. Therefore it is strongly
recommended to install backup devices and alarm
or warning devices. Spare equipment should also
be available at the owner’s site. Equipment
manufactured by the manufacturer is protected
against normal line surges. High surges caused
by thunder storms or power supply equipment
may damage this equipment. For added security
against line voltage surges it is recommended that
surge and noise suppression devices be installed
at the electrical distribution panel. Use of shielded
cable for probes is recommended for protection
against lightning. These devices are available
from most electrical supply distributors.
RECOMMENDATIONS
The manufacturer recommends that all installation
procedures described herein be performed by a
qualified electrician or installation technician.
Further more the manufacturer recommends to
test all the functions and equipment connected to
the VPM, including the alarm system and backup
devices, after installation, after changes to the
installation and every month after that.
Fuse verification and replacement, as well as the
proper setting of control values shall be the
responsibility of the owner of this equipment.

difficult to remove, drill out if possible.
It is strongly recommended to install PVC conduits.
Make sure that the cables are water tight.
2.3.2 - Connecting 115VAC Fans
Refer to figure 1.
•Connect L1 of the power source to terminal 1 for fan 1.
•Connect the ground wire of the power source to the
ground wire in the housing of the unit.
•Connect the neutral side of the power source to the
neutral of fan 1.
•Connect the live lead of fan 1 to terminal 2.
2.3.3 - Connecting 230VAC Fans
Refer to figure 2.
•Connect L1 of the power source to terminal 1 for fan 1.
•Connect the ground wire of the power source to the
ground wire in the housing of the unit.
•Connect L2 of the power source to the appropriate
terminals of fan 1.
•Connect the appropriate lead of fan 1 to terminal 2.
Do not apply power to the control panel until all con-
nections have been completed!
Maximum load of 10 amps per stage only.

2.3.4 - Connecting to the master control
•Install a 18 - 22 AWG cable pair between the VPM-
1 and the LX control. The maximum cable length is
of 500 feet (150m).
•Connect one end of the cable to the (+) and (-)
terminals of the VPM-1 low voltage terminal block.
Refer to the bottom left corner of figures 1 or 2.
•All wires between the master control and the VPM-
1, as well as the probes should be shielded.
•Do not place low voltage cable into power conduit.
2.4 POWERING UP
Before powering up the VPM-1,
•Screw the faceplate to the casing of the unit using
the four screws previously removed.
•Verify the fan’s motor specifications. The current
must not exceed 10 A per stage
•To test the unit use the manual override parameter
indicated on the master control.
•When you have completed verifying the fan
operation, set the manual override parameter on
the master control to AUTO.
When using 3 phase power, ensure that the
phase supplying the master control and variable
fan is the same. Otherwise the control signal of
the master control will be too early or too late and
the fan will not rotate as expected.
