1.4.3 Commissioning
WARNING!
Danger of injury through electric shock.
Non-observance of warnings can result in serious injury or damage.

Only hard-wired network connections are permitted. The device must be grounded (DIN
EN 61140; VDE 0140-1).

Frequency converters of the INVEOR series can contain contact currents (leakage currents)
> 3.5 mA. According to chapter 4.3.5.5.2 of DIN EN 61800-5-1, a reinforced protective
ground wire (at least 10 mm
2
Cu or 16 mm
2
Al) must be used.

If three-phase frequency converters are in use, it is not permitted to use standard type A FI
protection switches, or RCDs (residual current-operated protective devices) to protect from
direct or indirect contact. According to DIN VDE 0160, section 5.5.2 and EN 50178, sec-
tion 5.2.11.1, the FI protection switch must be universal current sensitive (RCD type B).

The following terminals can lead to dangerous currents even when the motor is not run-
ning:
o
Supply terminals X1: L1, L2, L3
o
Motor connection terminals X2: U, V, W
o
Connecting terminals X6, X7: Relay contacts for relays 1 and 2

If different voltages are in use (e.g. +24 V/230 V), crossing cable runs are never permitted.
The operator must also ensure compliance with the applicable regulations (e.g. double or
strengthened insulation acc. to DIN EN 61800-5-1).

The drive control contains components susceptible to electrical discharge. These compo-
nents can be destroyed through improper handling; therefore, precautionary measures
against electrostatic charges must be taken when work is performed on these components.
1.4.4 Operation
WARNING!
Danger of injury due to electric shocks or restarting motors.
Non-observance of warnings can result in serious injury or damage.

Observe the following instructions during operation:
o
The drive control works with high voltages.
o
When electrical devices are operated, some parts of them are always subject to dan-
gerous voltage.
o
Emergency off equipment according to DIN EN 60204-1; VDE 0113-1:2007-06 has to
be functional in all operating modes of the control device. Resetting the emergency
stop equipment may not result in uncontrolled or undefined restarting.
o
In order to ensure safe disconnection from the mains, the mains cable has to be all-
pole disconnected from the drive control.
o
Certain parameter settings can result in the drive control restarting automatically after
the supply voltage has failed.
