1.3.6 Risks associated with live electric parts
Voltage related risks, general
Work on the electrical equipment of the Product must be performed by a qualified
electrician in accordance with electrical regulations.
Although troubleshooting may, on occasion, need to be carried out while the power
supply is turned on, the Product must be turned off (by setting the main switch to
OFF) when repairing faults, disconnecting electric leads, and disconnecting or
connecting units.
The main supply to the Product must be connected in such a way that it can be
turned off from outside the working space of the Product.
Make sure that no one else can turn on the power to the controller and Product
while you are working with the system. A good method is to always lock the main
switch on the controller cabinet with a safety lock.
The necessary protection for the electrical equipment and Product during
installation, commissioning, and maintenance is guaranteed if the valid regulations
are followed.
Voltage related risks, IRC5 controller
A danger of high voltage is associated with, for example, the following parts:
•
Be aware of stored electrical energy (DC link, Ultracapacitor bank unit) in
the controller.
•
Units such as I/O modules, can be supplied with power from an external
source.
•
The main supply/main switch
•
The transformers
•
The power unit
•
The control power supply
•
The rectifier unit (Note: capacitors!)
•
The drive unit
•
The drive system power supply
•
The service outlets
•
The customer power supply
•
The power supply unit for additional tools, or special power supply units for
the machining process.
•
The external voltage connected to the controller remains live even when the
Product is disconnected from the mains.
•
Additional connections.
Voltage related risks, product
A danger of low voltage is associated with the Product in:
•
The power supply for the motors.
•
The user connections for tools or other parts of the installation.
