DANGER
Risk of injury due to electric shock!
The non-observance of warnings can result in severe bodily injury or sub-
stantial property damage.
1. Only hard-wired grid connections are permitted. The device must be earthed
(DIN EN 61140; VDE 0140-1).
2. The drive controls may have contact currents > 3.5mA. According to DIN EN
61800-5-1 chapter 4.3.5.5.2, an additional protective earth conductor with the
same cross section as the original earth conductor must be attached. The
possibility of connecting a second protective earth conductor is located un-
derneath the power supply (with marked ground symbol) on the outside of the
device. For the connection, a suitable M6x15 screw (torque: 4.0 Nm
[2.95 ft lbs]) is included in the scope of delivery of the adapter plates.
3. When using alternating current drive controls, conventional FI circuit breakers
of type A, also known as RCDs (residual current-operated protective devices)
are not permitted for the protection of direct or indirect contact! As per DIN
VDE 0160, section 5.5.2 and EN 50178, section 5.2.11.1, the FI circuit breaker
(RCD type B) must be suitable for all types of current.
4. The following terminals can also lead to dangerous voltages when the engine
is at a standstill:
 the mains connection terminals X1: L1, L2, L3
 the motor connection terminals X2: U, V, W
 the connection terminals X6, X7: Relay contacts relays 1 and 2
 the PTC connection terminals T1/T2
5. When using different voltage levels (e.g. +24V/230V), always ensure that lines
do not cross! Furthermore, the operator must ensure that the applicable regu-
lations are adhered to (e.g. doubled or reinforced insulation according to DIN
EN 61800-5-1).
6. The drive control contains electrostatically sensitive assemblies. These as-
semblies can be destroyed due to improper handling, therefore safety meas-
ures against electrostatic loading must be adhered to when work must be
done on these assemblies.
