This manual contains clearly marked cautions and warnings that are intended for your personal
safety and to avoid any unintentional damage to the product or connected appliances.
Read the information included in cautions and warnings carefully.
The cautions and warnings are marked as follows:
1.1
Danger
Table 1. Warning signs
= DANGER! Dangerous voltage
= WARNING or CAUTION
= Caution! Hot surface
The
components of the power unit are live
when the drive is connected to mains
potential. Coming into contact with this voltage is
extremely dangerous
and may
cause death or severe injury.
The
motor terminals U, V, W and the brake resistor terminals are live
when the
AC drive is connected to mains, even if the motor is not running.
After disconnecting
the AC drive from the mains,
wait
until the indicators on the
keypad go out (if no keypad is attached, see the indicators on the cover). Wait 5
more minutes before doing any work on the connections of the drive. Do not open
the cover before this time has expired. After expiration of this time, use a
measuring equipment to absolutely ensure that no voltage is present.
Always
ensure absence of voltage before starting any electrical work!
The control I/O-terminals are isolated from the mains potential. However, the
relay outputs and other I/O-terminals may have a dangerous control voltage
present even when the AC drive is disconnected from mains.
Before connecting
the AC drive to mains make sure that the front and cable
covers of the drive are closed.
During a ramp stop (see the Application Manual), the motor is still generating
voltage to the drive. Therefore, do not touch the components of the AC drive
before the motor has completely stopped. Wait until the indicators on the keypad
go out (if no keypad is attached, see the indicators on the cover). Wait additional 5
minutes before starting any work on the drive.
