EMC INSTALLATION
(continued)
23
Overview
The Pentek Intellidrive is a Variable Frequency Drive
(VFD). As with all VFD’s, this device may cause
electromagnetic interference if it is not installed
correctly. Following these instructions will ensure that
this device will comply with the relevant Australian EMC
standards.
These instructions should be read in conjunction with
the Pentek Intellidrive Installation Manual, as supplied
with the device.
Enclosure
The Pentek Intellidrive shall be installed in an EMC
shielded enclosure. The EMC enclosure shall be rated
for use from 0 up to 1GHz and shall have a rated
attenuation of at least 35dB at 1GHz.
Pentair Australia recommends the Hoffman®
CSD24248LG- EMC enclosure.
Enclosure Installation
1. Open the enclosure door and remove the mounting
panel.
2. Line-up the Intellidrive on the desired location on
the mounting panel. Take care to allow enough
room for easy access to wiring points on the
Intellidrive.
Note: The enclosure may also be used to house
other electrical components. All wiring must be
completed by a qualified electrician in accordance
with the Wiring Rules (AS/NZS 3000).
3. To mount the drive, mark the locatio
n of the top
keyhole on the mounting panel. Drill a hole in the
mounting panel at this mark. Drive a bolt into the
mounting panel and hang the Intellidrive on it.
4. Remove the screw on the bottom of the front cover
on the Intellidrive and lift the cover off. Mark the
locations of the bottom two mounting holes. Drill
holes for the bottom two mounting holes and mount
the drive using bolts / screws in all holes.
Note: Use serrated washers on mounting bolts /
screws to cut through paint and provide a low
resistance earth connection.
5. Return the mounting panel and Intellidrive to the
enclosure and bolt securely in place.
ADDENDUM - INSTALLATION FOR ELECTROMAGNETIC COMPATIBILITY (EMC)
Earthing
Note: All earth wiring shall be installed as per the Wiring
Rules (AS/NZS 3000).
Connect an earth strap between the enclosure and the
enclosure door to ensure a low resistance earth
connection. The earth strap shall be of sufficient wire
diameter to handle the total load of all devices
connected to the enclosure and in accordance with the
Wiring Rules.
The enclosure shall be earthed via the mains earth
connection or directly via a ground stake, where the
wire run is long, in accordance with the Wiring Rules.
Motor Cable
The cable used to connect from the Intellidrive to the
submersible pump motor shall be a shielded cable. The
shielded cable section shall run for the above ground
length between the Intellidrive and the bore.
The shielded cable shall enter the enclosure, housing
the Intellidrive, via a shielded cable gland. Select a
shielded gland of suitable size for the shielded cable
used.
Note: The mains supply cable does not need to be
shielded.
1. Use a hole saw or large drill bit to make a hole for
the shielded cable gland, in the enclosure wall, at
the desired location for cable entry.
2. Insert the shielded cable gland into the hole and
tighten the nut. Ensure the nut is tight enough to cut
through the enclosure paint.
3. Remove the cable sheathing, from the end of the
cable, to expose the shielding. Remove a sufficient
amount to ensure the shielding will be in contact
with the cable gland and also to allow enough
length of cable to connect to the Intellidrive.
4. Tighten the gland nut.
Warning
This is a Class A product. In a domestic environment,
this product may cause radio interference, in which
case the user may be required to take adequate
measures.
Warning
Risk of high-voltage electric shock from EMI/RFI filter
inside drive. Before connecting or disconnecting any
wires inside the drive, turn off power to the drive and
WAIT 5 MINUTES for retained voltage to discharge.
Warning
Make all wiring connections, then close and fasten the
cover before turning on power to the drive. Do not open
the box when power is connected to the drive.
Warning
The Intellidrive must be installed by a qualified
electrician and must be installed in accordance with the
Wiring Rules (AS/NZS 3000).
