●
Do not touch hot surfaces of, for example, braking resistors, heat sinks,
supply units and drive controllers, motors, windings and laminated
cores!
●
According to the operating conditions, temperatures of the surfaces can
be higher than 60 °C (140 °F) during or after operation.
●
Before touching motors after having switched them off, let them cool
down for a sufficient period of time. Cooling down can require up to 140
minutes! The time required for cooling down is approximately five times
the thermal time constant specified in the technical data.
●
After switching chokes, supply units and drive controllers off, wait 15 mi‐
nutes to allow them to cool down before touching them.
●
Wear safety gloves or do not work at hot surfaces.
●
For certain applications, and in accordance with the respective safety
regulations, the manufacturer of the machine or installation must take
measures to avoid injuries caused by burns in the final application.
These measures can be, for example: Warnings at the machine or in‐
stallation, guards (shieldings or barriers) or safety instructions in the ap‐
plication documentation.

Risk of injury by improper handling!
●
Do not attempt to reactivate low batteries by heating or other methods
(risk of explosion and cauterization).
●
Do not attempt to recharge the batteries as this may cause leakage or
explosion.
●
Do not throw batteries into open flames.
●
