ELECTRICAL INSTALLATION PROCEDURE
6.1
GENERAL NOTES FOR VARIABLE FREQUENCY DRIVE (VFD) SYSTEMS
6.1.1
MOUNTING
Mount the drive as close as possible to the motor to be controlled (
20
ft
.
or
6m
MAX.
);
Mount the drive in a location that will insure easy access and will avoid all contact with water;
Allow
12"
free space all around the drive for heat dissipation;
Do not mount the drive close to heating units or elements;
Do not use any power correction or surge protection device, at the drive output;
Do not use any switching device at the drive output;
Do not mount the drive close to magnetic detection system.
6.1.2
POWER WIRING
(Refer to the wiring diagram supplied with the VFD)
When servicing, wait at least 3 minutes before interfering with wiring, in order to allow capacitors
discharge;
Use only non-metallic conduit to run the wire between the electrical panel and the drive, or between the
drive and the motor;
Use power wire copper type, 600V,105C, USA or Canada, REW, XLPVC or TEW;
Size all conductors for 3% voltage drop;
Run a circuit exclusively for the drive;
Physically split input and output wiring of the drive;
On humidity applications we recommend using water tight connectors and installing a drip loop on the
motor;
The current required for the VFD and Motor is different for the various typical voltage systems;

The VFD is rated IP 55. Consult your electrical contractor and the VFD manufacturer for input regarding
multiple VFD branch circuits and potential for input line reactors.
6.1.3
CONTROL WIRES
(Refer to the wiring diagram supplied with the VFD)
Use only shielded cable for control signal connections (4 conductors);
There are two control signals from the temperature controller:
o
0-10VDC-from control terminals S+ and S-;
o
The start-up signal from control terminals E-F.
Shield should be connected at one end only;
The low voltage wiring shall be separate from the power wiring. This is a 0-10V DC analog signal.
Do not run control cables along with power cables;
##""%%"%!#""""#!##"!""#"#"!""!%#
If needed, cross control and power cables at 90 degrees.
