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.
