Opening the control unit
Always take adequate precautions before opening the control unit. Although the
connections for the control signals and the switches are isolated from the mains
voltage, do not touch the control board when the drive system is switched on.
Precautions to be taken with a connected motor
If work must be carried out on a connected motor or on the driven machine,
the mains voltage must always be disconnected from the drive system first.
Earthing
The control unit must always be earthed via the mains safety earth connection.
EMC Regulations
In order to comply with the EMC Directive, it is absolutely necessary to follow
the installation instructions. All installation descriptions in this manual follow
the EMC Directive.
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor, before all the motor
cables have been disconnected from the drive system.
Condensation
If the control unit is moved from a cold (storage) room to a room where it will
be installed, condensation can occur. This can result in sensitive components
becoming damp. Do not connect the mains voltage until all visible dampness
has evaporated.
Incorrect connection
The control unit is not protected against incorrect connection of the mains
voltage, and in particular against connection of the mains voltage to the motor
outlets R, Y and B. The control unit can be damaged in this way.
WARNING! Always switch off the mains voltage before opening
the control unit.
Wait at least 5 minutes before starting work.
