14 Safety instructions
General safety in installation, start-up and maintenance
These instructions are for all personnel who do work on the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to
the equipment can occur.
•
Keep the drive in its package until you install it. After unpacking, protect the
drive from dust, debris and moisture.
•
Use the required personal protective equipment: safety shoes with metal toe
cap, safety glasses, protective gloves and long sleeves, etc. Some parts have
sharp edges.
•
Beware of hot surfaces. Some parts, such as heatsinks of power
semiconductors, and brake resistors, remain hot for a while after disconnection
of the electrical supply.
•
Vacuum clean the area around the drive before the start-up to prevent the
drive cooling fan from drawing dust inside the drive.
•
Make sure that debris from drilling, cutting and grinding does not go into the
drive during installation. Electrically conductive debris inside the drive can
cause damage or malfunction.
•
Make sure that there is sufficient cooling. See the technical data.
•
Before you connect voltage to the drive, make sure that all covers are in place.
Do not remove the covers when voltage is connected.
•
Before you adjust the drive operation limits, make sure that the motor and all
driven equipment can operate throughout the set operation limits.
•
Before you activate the automatic fault reset or automatic restart functions
of the drive control program, make sure that no dangerous situations can
occur. These functions reset the drive automatically and continue operation
after a fault or supply break. If these functions are activated, the installation
must be clearly marked as defined in IEC/EN/UL 61800-5-1, subclause 6.5.3,
for example, "THIS MACHINE STARTS AUTOMATICALLY".
•
The maximum number of drive power-ups is five in ten minutes. Too frequent
power-ups can damage the charging circuit of the DC capacitors.
•
If you have connected safety circuits to the drive (for example, Safe torque off
or emergency stop), validate them at start-up. See separate instructions for
the safety circuits.
•
Beware of hot air exiting from the air outlets.
•
Do not cover the air inlet or outlet when the drive is running.
