Drive.
• Before doing any service or maintenance inside
Drive or when connecting or disconnecting any wires
inside Drive:
1. DISCONNECT power.
2. WAIT 5 minutes for retained voltage
to discharge.
3. Open box.
• Before starting any wiring or inspection procedures,
check for residual voltage with a voltage tester.
• NEVER connect power wiring to Drive before
mounting the box.

Risk of fire. Can cause severe injury,
property damage or death if installed with incorrect
or inadequate circuit breaker protection. To ensure
protection in the event of an internal fault in the
Pentek Intellidrive, install the Drive on an independent
branch circuit protected by a circuit breaker (see
Table 2 for circuit-breaker sizing), with no other
appliances on the circuit.
Risk of burns. The Drive can become hot
during normal operation. Allow it to cool for
5 minutes after shut-down and before handling it to
avoid burns.
NOTICE To avoid damage to Drive or problems with
Drive:
• Connect output cables to 3-wire 1-phase and
3-phase submersible motors as follows:
Red to R, Yellow to Y, Black to B.
Any other order will reverse the motor rotation and
may damage the motor.
• Connect output cables to 2-wire 1-phase
submersible motors as follows:
Connect to Y and B only.
Connect Ground to green screw.
• Above ground 3-phase motors may have different
lead colors. Generally connect output leads
as follows:
R to L1, Y to L2, B to L3.
Verify rotation after startup.
• Do not modify equipment.
• Do not use power factor correction capacitors as
they will damage both motor and Pentek Intellidrive.
• Do not remove any parts unless instructed to do so
in Owner's Manual.
• Do not use a magnetic contactor on Drive for
frequent starting/stopping.
• Do not install or operate Drive if it is damaged or
parts are missing.
• Before starting Drive that has been in storage,
always inspect it and test operation.
• Do not carry out a megger (insulation resistance)
test on the control circuit of the Drive.
• Do not allow loose foreign objects which can conduct
electricity (such as screws and metal fragments)
inside Drive box at any time. Do not allow flammable
substances (such as oil) inside Drive box at any time.
• Ground Drive according to the requirements of the
National Electrical Code Section 250, IEC 536 Class
1, or the Canadian Electrical Code (as applicable) ,
and any other codes and ordinances that apply.
• All installation, service work, and inspections must
be done by qualified electrician.
