1.0 Safety
1.1 General warning
The voltage of the EC drive is dangerous whenever the drive is connected to the AC line.
Incorrect installation of the motor or drive may cause damage to the equipment, serious
injury or death. Comply with the safety instructions in this manual as well as local and
national rules and safety regulations.
1.2 Personal safety
1. Disconnect the EC drive from the AC line if repair work is to be carried out. Wait 4 minutes to allow for electrical
discharge before disconnecting motor and AC lines.
2. The [ON / OFF] input on the user interface panel of the EC drive does not disconnect the drive from the AC line. Do not
use it as a safety switch.
3. Do not remove the terminal lines for the motor and AC line supply while the EC drive is connected to the AC line.
Ensure that the AC line supply has been disconnected and then wait 4 minutes before removing motor and AC lines.
4. The motor can be started by means of digital commands, bus commands, references or a local start command
whenever the drive is connected to the AC line. Therefore, an unintended start may occur anytime power is applied.
Never service the drive or equipment when power is applied to the drive.
5. Before installing and operating this EC-controller please read this instruction carefully!
Warning:
It can be extremely dangerous to touch the electrical parts even when the
mains supply has been disconnected. Also ensure that other voltage
inputs are disconnected from load sharing through the DC bus. Wait at
least 4 minutes after the input power has been removed before servicing
the drive.
