System Design -
Typical Constant Pressure Systems
The following diagrams show typical single pump and multi-pump systems using the AQUAVAR con-
troller. Connection can be made directly to a water supply or water can be drawn from a supply tank or
well. In the case of supply tanks and wells, level switches, (item 10) can be used to shut down the
pumps when water is low. In the direct connection, a pressure switch on the suction side (item 8) can
be used.
A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintain pressure in the line when there is no demand. This will keep the pumps from continuing to run. With the
AQUAVAR controller, it is not necessary to have a large tank for supply purposes. In selecting a tank,
make sure it can withstand maximum system pressure
. The tank should have a capacity of at least
10% of the maximum system flow rate in gpm. Pre-charge the tank to the following:

4. Review all instructions and warnings prior to performing any work on the AQUAVAR controller.
5. Any safety decals MUST be left on the AQUAVAR controller unit and pump.
6. In addition to instructions contained in this manual, you must meet any local safety, electrical, or
plumbing codes and requirements. Installation, maintenance, or repair work must only be
carried out by trained, skilled, and qualified personnel, using proper protective gear and
tools.
7. The AQUAVAR controller drive head must be disconnected from the main power
supply before attempting any operation in the electrical or mechanical part of the
system.
Safety Instructions
When in operation, the motor can be stopped, but power remains at the drive head. The
motor and pump could start unexpectedly and produce serious injury. When the AQUAVAR
controller drive head is connected to the main power supply, the inverter power supply
and master control unit are also connected to the power supply.
Inspect AQUAVAR controller for any damage after unpacking from shipping crates.
Report any damage immediately to the carrier or distributor/dealer immediately.

8. The AQUAVAR controller has electronic safety devices which will stop the motor in the event of
electrical or thermal faults. This does not remove power to the AQUAVAR controller.
9. The system must be properly grounded before being put into operation. Use a common
ground for the entire system.
10. High voltage tests of the AQUAVAR controller may damage the electronic components.
Before carrying out such a test, bridge the incoming and outgoing terminals L1 - L2 - L3 - U - V W. Isolate the motor from the AQUAVAR controller drive to avoid incorrect capacitor metering inside
the AQUAVAR controller.
Safety Instructions
FAILURE TO DISCONNECT AND LOCKOUT ELECTRICAL POWER AND WAIT
FIVE MINUTES FOR C APACITOR DISCHARGE BEFORE SERVICING AQUAVAR
CONTROLLER CAN C AUSE SHOCK, BURNS, OR DEATH.
WARNING!
TOUCHING THESE COMPONENTS SERIOUSLY ENDANGERS LIFE! Voltages of up to
800 volts are possible (higher if there is a fault).
Before removing the AQUAVAR controller drive top cover, the system must be discon-
nected from the main power supply. After switching off the power supply, you must
wait at least 5 minutes before starting work on or inside the AQUAVAR controller drive
head. This allows the capacitors in the circuit to be discharged by the discharge
resistors.
Note
Care must be taken when connecting external control wires and jumpers to avoid short circuit to neighboring components.
Note
Repair of electrical faults can lead to the automatic restart of the motor and pump.
You must remove all main line power to the AQUAVAR controller before attempting to
correct a fault.

Installation Procedures
Step 2 - Mounting the AQUAVAR
II
controller:
AQUAVAR Controller
The AQUAVAR controller may be installed as a wall or panel mounted unit. The AQUAVAR controller may
be mounted up to 60 feet away from the pump motor*. In addition, alternative motor enclosures
may be selected such as ODP, explosion proof or wash down motors in addition to the TEFC enclosure required for on the pump mounting.
Typical applications for the AQUAVAR Wall Mount controller include:
1. Hazardous environment applications including high heat, humidity or combustibility.
2. Installation to an existing pumping system with non-standard motors.
3. Installations where the operator desires all controls to be grouped together.
Mounting of the AQUAVARII Controller
1. An alternative mounting style is used in the AQUAVAR
II
controller configuration.
In this style, the AQUAVAR
II
controller is supplied with a fan and mounting bracket already
installed and can be mounted to a wall or panel.
2. The mounting bolts for all units should be 1⁄4". The length of bolt and the strength of the
mounting surface must be adequate to support the weight of the AQUAVAR
II
controller.
3. The AQUAVAR
II
controller may be positioned up to 60 feet from the pump motor. The pump
motor must be three phase. Unlike the standard AQUAVAR controller, the motor may be
ODP, TEFC or explosion proof.*
4. Mount the AQUAVAR controller to the panel, wall or frame using bolts at the points indicated
on the following drawings. Be sure the unit is level and secured to the mounting surface
before continuing.
5. Ensure plenty of airflow for the AQUAVAR controller, when mounting.
*NOTE: If the AQUAVAR
II
controller is more than 60 feet wire length to motor, then the use of a
load reactor (impedance coil) is required.

Step 3 - Preliminary Inspection
Before storing or installing the AQUAVAR controller, thoroughly inspect the device for possible
shipping damage. Upon receipt:
1. Remove the controller from its package and inspect exterior for shipping damage. If damage is
apparent, notify the shipping agent and your sales representative.
2. Remove the cover and inspect the controller for any apparent damage or foreign objects.
Ensure that all mounting hardware and terminal connection hardware is properly seated,
securely fastened and undamaged.
3. Read the technical data label affixed to the controller and ensure that the correct horsepower
and input voltage for the application had been purchased.
4. If you will store the controller af ter receipt, place it in its original packaging and store in a
clean, dry place free from direct sunlight or corrosive fumes, where the ambient temperature
is not less than -20ºC (-4ºF) or greater than +65ºC (+149ºF).
Step 4 - Installation Precautions
Improper installation of the AQUAVAR controller will greatly reduce its life. Be sure to observe the
following precautions when selection a mounting location. Failure to obser ve these
precautions will void the warranty!
1. Do not install the controller in a place subjected to high temperature, high humidity, excessive
vibration, corrosive gases or liquids or airborne dust or metallic particles. See Technical Data
Appendix B for temperature, humidity and maximum vibration limits or contact factor
y.
2. Do not mount the controller near heat-radiating elements or in direct sunlight.
3. Mount the controller vertically and do not restrict the air flow to the heat sink fins.
4. The controller generates heat. Allow sufficient space around the unit for heat dissipation.

Step 5 - Considerations for Mounting AQUAVAR Controllers
in Host Enclosures
The AQUAVAR controller is available from stock in a variety of enclosures that meet the requirements
of almost any application. Yet, special applications (such as use in washdown environments or in
integrated systems) may make it desirable to mount AQUAVAR controllers in a host enclosure.
When the AQUAVAR controllers are mounted in a host enclosure, the watts dissipated by the drives
must be dissipated by the host enclosure. If this is not accomplished, the control circuitry of the
AQUAVAR controller will be damaged.
Two techniques are available for mounting AQUAVAR controllers in a host enclosure:
• The controllers may be entirely enclosed in the host enclosure or
• The controllers may be mounted with their cooling fins outside of the host enclosure.
The following sections discuss these two mounting techniques in greater detail.
Models Entirely Enclosed in the Host Enclosure
When an AQUAVAR controller is entirely enclosed in a host enclosure, the host enclosure must be
properly sized to dissipate the heat generated by the controller and any other power-dissipated
by the various models of the AQUAVAR controller at various switching frequencies. Use this
information to adequately size the host enclosure.
Models with Fins External to the Host Enclosure
By mounting an AQUAVAR controller so that its heatsink fins are outside of the host enclosure, you
may select a smaller host enclosure than that required when the controller is mounted entirely
inside the host enclosure. For most applications with this type of mounting, typically you will not
need such additional cooling devices as fans, heat exchangers or air conditioners.
The amount by which the load on the host enclosure is reduced is the amount of watts dissipated
by the heatsinks of the controllers. Table 3 shows the watts dissipated by each AQUAVAR model
after deducting the amount of watts dissipated by the heatsinks of the model. Use the values
shown in the table to adequately size the host enclosure.

Step 6 - Maintenance
Minimum Torque Values to Secure Cover
If you remove the cover of an IP55 AQUAVAR controller, it is imperative that the cover be
closed and re-secured with sufficient tightness to maintain environmental integrity. The table
below specifies the torque values for the bolts that secure the covers on the various models.
Step 7 - General Wiring Information
Wiring Practices
When making power and control connections, observe these precautions:
• Follow all Federal, State, NEC codes and local codes.
• Never connect input AC power to the motor output terminals T1/U, T2/V or T3/W – or
damage to the controller will result.
• Power wiring to the motor must have the maximum possible separation from all other power
wiring. Do not run in the same conduit, this separation reduces the possibility of coupling
electrical noise between circuits.
• Cross conduits at right angles whenever power and control wiring cross.
• Good wiring practice also requires separation of control circuit wiring from all power wiring.
Since power delivered from the controller contains high frequencies which may cause
interference with other equipment, do not run control wires in the same conduit or raceway
with power or motor wiring.
Considerations for Power Wiring
Power wiring refers to the line and load connections made to terminals L1/R, L2/S, L3/T and
T1/U, T2/V, T3/W respectively. Select power wiring as follows:
• Use only UL recognized wire. (Shielded or armored wire is recommended for power and motor
wiring.)
• Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V (Class 1 wire)
for 460 Vac and 575 Vac systems.

25-75 HP, 460 and 575 Vac input 12 in-lbs 1.35 Nm
Electrical Connections continued
• Use circuit breakers on the incoming power lines.
• Grounding must be in accordance with NEC and CEC. If multiple AQUAVAR controllers are
installed near each other, each must be connected to ground. Take care to not form a ground
loop. Maintain a common ground.
• Wire must be made of copper and rated 60 / 75ºC (unless otherwise specified in the table
below). Refer to Tables 4, 5 and 6 for recommended wire gauges and temperature ratings.
Considerations for Control Wiring
Control wiring refers to the wires connected to the control terminal strip. Select control wiring
as follows:
• Shielded wire is recommended to prevent electrical noise interference from causing improper
operation or nuisance tripping.
• Use only UL™ recognized wire.
• Wire voltage rating must be at least 300 V for 230 Vac systems.

Step 8 - Input Line Requirements
Line Voltage
See the Power and Current Ratings table for the allowable fluctuation of AC line voltage for your
particular model. A supply voltage above or below the limits given in the table will cause the
drive to trip with either an overvoltage or under voltage fault.
When supplying line voltages other than the factory default values (either 230 Vac, 460 Vac or
575 Vac depending on the model), set the Supply Voltage parameter to the appropriate value.
Exercise caution when applying the AQUAVAR controller on low-line conditions.
For example, and AQUAVAR controller will operate properly on a 208 Vac line – but the maximum
output voltage will be limited to 208 Vac. Now if a motor rated for 230 Vac line voltage is
controlled by this drive, higher motor currents and increased heating will result.
Therefore, ensure that the voltage rating of the motor matches the applied line voltage. If other
than 60 Hz output is desired, proper V/Hz can be programmed into the AVII by setting the
Nom Mtr Voltage and Nom Mtr Freq parameters.
Use of Isolation Transformers and Line Reactors
The AQUAVAR controller is is per fectly suitable in most cases for direct connection to a power source
as specified in this manual and the technical nameplate affixed to the unit. There are however a
few cases where a properly sized isolation transformer or line reactor should be employed to
minimize the risk of drive malfunctionor damage or nuisance tripping:
• As noted in
Table 7
, transformer sizing, when line capacity is greater than 10 times the KVA
rating of the drive. Consult the factory for assistance in sizing the reactor.
• When power factor correction capacitors are employed on the drive’s power source.
• When the power source is known to be subject to transient power interruptions or
significant voltage spikes.
• When the power source supplying the drive also supplies large devices such as DC drives
that contain controller rectifiers.

Phase Imbalance
Phase voltage imbalance of the input AC source can cause unbalanced currents and excessive
heat in the drive’s input rectifier diodes and DC bus capacitors. Phase imbalance can also damage
motors running directly across the line.

Note that when testing for a ground fault, do not short any motor lead (T1/U, T2/V or T3/W) back
to an input phase (L1/R, L2/S or L3/T).
As shown in Diagram 5, it is necessary to provide fuses and a disconnect switch for the input AC
line in accordance with all applicable electrical codes. The drive is able to withstand a 110% over
load for 60 s. For maximum protection of the drive, use the fuses listed in Tables 9, 10 and 11

board of the AV IIdrive. (The actual control board cannot be accessed by the user.) These
terminals are prewired by the factory with color coded wires below.
Note that due to labeling constraints, the labels for some terminals start on the left (either on
the side or top of the terminal block), are interrupted by the terminal screw, and then finish on
the right (either on the side or top of the terminal block). For example, terminal A11 is labeled
with A on the left side of the block and 11 to the right of the terminal screw on top of the
block. Similarly, terminal NC2 is labeled with N to the left of the terminal screw on top of the
block and then C2 on the
right side of the block.
As is shown in the figure,
the terminals are divided
into four terminal blocks,
each of which pulls apart
for ease of field wiring:
• TB1 - analog input,
analog output and
digital output terminals.
• TB2 - output relay 1 (R1).
• TB3 - output relay 2 (R2).
• TB4 - digital input
terminals.
Table 12 starting on the
next page describes the
control terminals.
Cable connector will fit on one way only! Do not force on or damage may occur.

Table 12: Description of AV II Drive Control Terminals (Internal Drive)
Terminal Description
TB2 Terminal Block
Common terminal for the first auxiliary relay. The function of the relay is
RC1 set by parameter R1 Configure. The default setting is for the relay to
activate when a fault is detected (Drv Flted).
NC1 Normally-closed contact for the first auxiliary relay. It will open when the
relay is activated.
NO1 Normally-open contact for the first auxiliar y relay. It will close when the
relay is activated.
TB3 Terminal Block (Drive Run Contacts)
Common terminal for the second auxiliary relay. The function of the relay
RC2
is set by parameter ROUT R2 Config. The default setting is for the relay
to activate when the drive is running.
The contact ratings are 115 VAC at 1 A or 230 VAC at 0.5 A .
NC2
Normally-closed contact for the second auxiliary relay. It will open when
the relay is activated.
NO2
Normally-open contact for the second auxiliary relay. It will close when
the relay is activated.
TB4 Terminal Block
Enable terminal. A jumper is placed between this terminal and the +2
terminal at the factory. You may replace this with a contact if desired. The
EN
circuit from EN to +24 must be closed for the drive to operate.
Note that unlike all other terminals, this terminal cannot be configured
for “pull-down logic.” That is, a high input to this terminal is always
regarded as true – and must be present if the drive is to operate.
Digital inputs. The function of a digital input is configured by the
D3 to D10 parameter with the same name as the digital input in the DI Configure
parameter group.
Digital input. In 3-wire control, this must be a Stop input. In 2-wire
D2 control, it may be configured to another function with parameter
D2 Configure.
D1 Digital input. This must be a Start or Run input.
6. For multi-pump systems:Use a three core shielded cable to connect terminals 1, 2, and 3
on X5 between the AQUAVAR controller units. These are the RS-485 inter face connections.
(See Diagram 11 and 13). Note: either RS485 port can be used.
• Connect pump one to pump two, two to three, and three to four (maximum is 4 pumps).
7. External pressure switch or float switch- (if used) to check incoming pressure and low/no
suction. Connect to terminal block X1 at the 6 and 7 location. Refer to Diagram 11.
When using a suction pressure switch, set the cut off at the maximum NPSH required by the pump.
8. External on/off
If used to turn the AQUAVAR controller on or off from an external panel or controller, connect to
terminal block X1 at the 4 and 5 location (refer to Diagram 7, page 24).
9. Analog output of pressure
A meter can be connected to X9 pins 2 and 1 for remote display of actual system pressure.
The meter must be 0-10 VDC volt with no more than 2 mA.
10. Second Sensor Input
The ground pin (X1-10) used for analog output can also be used to bridge a connection for
a second sensor. This can be digital (on/off) such as a switch which would be connected
between X1-10 and X1-14. Another choice is a sensor with a voltage signal of 0-10V or 2-10V
which would be connected to X
1-10 and X1-13. A final choice is a 4-20 mA current sensor
which would be connected to pins X
1-10 and X1-12.

Installation Procedures
Power supplies using G.F.I. breakers will cause nuisance tripping which will result in the
AQUAVAR
controller displaying an “undervoltage” fault.
Note
If an external switch is NOT used, install a jumper wire between X1 Locations 4 and 5.
