2 VST Variable Speed Pump Installation and User’s Guide
Electrical Installation
Note: ALWAYS reinstall the drive lid onto the field wiring compartment when leaving the pump unsupervised during
servicing. This will prevent foreign matter (i.e. rainwater, dust, etc.) from accumulating in the drive.
Note: When connecting the pump to an automation system (IntelliTouch
®
, EasyTouch
®
, SunTouch
®
Control Systems
and IntelliComm
®
Communication Center), continuous power must be supplied to the pump by connecting it directly
to the circuit breaker. When using an automation system, be sure that no other lights or appliances are on the same
circuit.
Wiring
1. Be sure all electrical breakers and switches are turned
off before wiring motor.
2. Be sure that the supply voltage meets the requirements
listed on the motor nameplate. If these requirements
are not met, permanent motor damage may occur.
3. For wiring sizes and general guidelines for proper
electrical installation, please follow the specifications
defined in the National Electric Code and any local
codes as required.
4. Use strain relief and be sure all electrical connections
are clean and tight.
5. Cut the wires to the appropriate length so they do
not overlap or touch when connected.
6. Reinstall the keypad after wiring the pump by plugging
the cover back into the drive wiring connection and
re-seating the keypad in the desired orientation with
the four (4) corner screws.
Note: Ensure that the keypad cable is not pinched
between the drive and keypad during re-seating.
Grounding
1. Permanently ground the motor using the green ground
screw, as shown below. Use the correct wire size
and type specified by National Electrical Code. Be
sure the ground wire is connected to an electrical
service ground.
2. The pump should be permanently connected to either
a circuit breaker, 2-pole timer or 2-pole relay.
Note: If AC power is supplied by a GFCI circuit
breaker, the pump should be wired on its own
independent circuit unless the pump is operated
in tandem with a Pentair salt chlorine generator.
Bonding
1. Bond the motor to the structure in accordance with the
National Electrical Code. Use a solid copper bonding
conductor not smaller than 8 AWG. For Canadian
installations, a 6 AWG or larger solid copper bonding
conductor is required. Run a wire from the external
bonding screw or lug to the bonding structure.
2. Connect the wire from the accessible bonding lug
on the motor to all metal parts of the swimming
pool, spa, or hot tub structure and to all electrical
equipment, metal conduit, and metal piping within 5
feet (1.52 meters) of the inside walls of the swimming
pool, spa, or hot tub. Run a wire from the external
bonding screw or lug to the bonding structure.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This pump must be installed by a licensed or certified electrician or
a qualified service professional in accordance with the National Electrical Code and all applicable local codes and ordinances.
Improper installation will create an electrical hazard which could result in death or serious injury to users, installers, or others due
to electrical shock, and may also cause damage to property.
Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in
death or serious injury to service people, users or others due to electric shock.
Read all servicing instructions before working on the pump.
Note: When the pump is started and stopped by removing
power with a relay or timer, a two-pole device should
be used to apply and remove power to both POWER
LINE TERMINALS.
Pentair offers 2-Pole 20 Amp GFCI breakers (P/N
PA220GF) which offer 6 milliamp personnel protection
while meeting 2008 to current NEC Standards for Pool
Pumps.
STORED CHARGE - Wait at least sixty (60)
seconds before servicing.
