3. Electrical
Installation
3.1 Safety
Electric shock hazard!
Disconnect and
ISOLATE
the Optidrive before attempting
any work on it. High voltages are present at the terminals and within the drive for up
to 10 minutes after disconnection of the electrical supply.
•
Optidrives should be installed only by qualified electrical persons and in accordance with
local and national regulations and codes of practice.
•
The Optidrive has an Ingress Protection rating of IP20. For higher IP ratings, use a
suitable enclosure.
•
Where the electrical supply to the drive is through a plug and socket connector, do not
disconnect until 10 minutes have elapsed after turning off the supply
•
Ensure correct earthing connections, see diagram below
•
The earth cable must be sufficient to carry the maximum supply fault current which
normally will be limited by the fuses or MCB
3.2 Precautions
•
Ensure that the supply voltage, frequency and number of phases (single or three phase)
correspond to the rating of the Optidrive as delivered
•
An isolator or similar should be installed between the power supply and the drive
•
Never connect the mains power supply to the Optidrive output terminals UVW
•
Protect the drive by using slow-blow HRC fuses or an MCB located in the mains supply
to the drive
•
Do not install any type of automatic switchgear between the drive and the motor
•
Wherever control cabling is close to power cabling, maintain a minimum separation of
100 mm and arrange crossings at 90
o
•
Ensure that screening or armouring of power cables is effected in accordance with the
connections diagram below
•
Ensure that all terminals are tightened to the appropriate torque (see table, left)
Connect drive according to the following diagram, ensuring that motor terminal box
connections are correct. There are two connections in general : Star and Delta. It is essential
to ensure that the motor is connected in accordance with the voltage at which it will be
operated. For more information, refer to the following diagram
For recommended cabling and wiring sizing, refer to section 7.4.
It is recommended that the power cabling should be 3-core or 4-core PVC-insulated
screened cable, laid in accordance with local industrial regulations and codes of practice.
The ground terminal of each Optidrive should be individually connected DIRECTLY to the
site earth (ground) bus-bar (through the filter if installed) as shown. Optidrive ground
connections should not loop from one drive to another, or to, or from any other equipment.
Ground loop impedance must conform to local industrial safety regulations. To meet UL
regulations, UL approved ring crimp terminals should be used for all earth wiring
connections.
