Pressure Tank Recommendations
Minimum tank size is 8 litres. Use a pre-
charged pressure tank with Drive, as shown in
Table 6. The tank size must equal at least 20
percent of the pump’s rated flow in litres per
minute (LPM), but cannot be less than 8 litre
capacity. For example, a pump rated at 30 LPM
would require a tank of 8 litres capacity or
larger. A pump rated at 200 LPM would require
a 40 litre tank or larger. Tanks larger than 40
litre can be used, but may require adjustment
of Wake Delay parameter.

NOTICE
Set pressure tank’s pre-charge to 70
percent of the system operating pressure.
When using an external set point as well as
an internal set point, pre-charge tank to 70
percent of the lower setpoint of the two.
Some applications may require a different
percentage when determining the setpoint.
Transducer Connections
A 0-668 kPa 4-20 mA transducer is provided
with Drive. Install the transducer downstream
of tank, as shown in Figure 1. Install transducer
in a tee in a straight section of pipe with at
least 30cm of straight pipe on each side of the
tee (i.e., all fittings must be at least 30cm away
from transducer).
Feed transducer cable through the open 13mm
conduit hole on bottom of the Drive enclosure.
As shown in Figure 9, connect the red wire
of the transducer cable to AI+, connect black
wire to AI–, and connect the green cable shield
to the metal cable shield screw.
To connect the transducer wires:
1. Strip wire 13mm
2. Push spring terminal up with finger
or slotted screwdriver
3. Insert wires from bottom
4. Release spring terminal
Input Power Connections
The input power terminals are located on
the lower left side and are marked L1 and
L2 (see Figure 9). There is a ground screw
for the input ground wire to the right of the
connector (torque to 1.5 Nm). Feed wire
through the 20mm conduit hole on the bottom
left side and into appropriate terminals. If wire
is large enough to require a larger conduit
hole, remove the 3.2cm knockout and use
appropriate conduit connections.
To determine the correct wire sizes for
installation, see Table 3.
NOTICE
The PENTEK INTELLIDRIVE only
accepts 230V single phase input power. If
incoming power does not match this, have a
qualified electrician alter supply voltage to
230V/1Ph before connecting it to the Drive.

Wiring
To allow for ease of wiring, the enclosure
wiring area is free of electronics other than
the terminals. Conduit holes and knockouts
are located so that the wire can be fed straight
through to the connectors, with minimal
bending. The terminals accept 1.5mm²-16mm²
wire.
For wire sizing refer to table 3, page 6.
NOTICE
For convenience in wiring, the input
and motor terminals unplug from the box. Pull
them down to remove them for ease of access,
as shown in Figure 8.
Verify that the terminal connectors are
completely seated when you replace them.
It is best practice to connect all output wires
(larger wire gauge) first, then all input wires.
Pump Connections
If the INTELLIDRIVE is used with above ground
motors not rated for Variable Frequency Drive use,
maximize motor life by limiting lead length to 8.0m.
The output of the Drive is single phase (2-wire
or 3-wire) or 3-phase, depending on motor
selection during startup.
The output power terminals (motor wire
connections) are located on the lower right
side of the Drive and are labeled R (Red), Y
(Yellow), and B (Black). See Tables 3.
Feed the motor cable through the 20mm conduit
hole on the bottom right side and into the
appropriate terminals. If the wire is large enough
to require a larger conduit hole, remove the
3.2cm knockout and use the appropriate conduit
connections. Attach the motor ground wire to
the grounding screw, located to the upper right
of the terminal block. Attach the motor power
wires to the terminals as shown in Figure 9.
NOTICE
Drive does not sense motor
temperature and will not protect motor from
over heating.
