This manual contains clearly marked cautions and warnings which are intended for your per-
sonal safety and to avoid any unintentional damage to the product or connected appliances.
Please read the information included in cautions and warnings carefully.
The cautions and warnings are marked as follows:
Table 1. Warning signs
1.1
Danger
= DANGEROUS VOLTAGE!
= WARNING or CAUTION
The
components of the power unit of the drive are live
when the drive is con-
nected 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 drive is connected to mains, even if the motor is not running.
After disconnecting
the 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 measur-
ing 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 drive is disconnected from mains.
Before connecting
the drive to mains make sure that the front and cable covers
of the drive are closed.
During a coast stop (see the Application Manual), the motor is still generating
voltage to the drive. Therefore, do not touch the components of the 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 min-
utes before starting any work on the drive.
