Connecting the Voltage Supply

Danger to life due to electric shock
Under fault conditions, when working on the power supply circuit there may be dangerous
voltages present on the product. This can result in death or serious injury.
• For power supply units with a fixed connection, make sure that a disconnection unit (e.g.
miniature circuit breaker) is present outside the power supply unit.
• For power supply units with a plug connection, make sure that the electrical outlet for the
power supply unit is close to the power supply unit.
• The disconnection unit and the electrical outlet for the power supply unit must be freely
accessible at all times.
Damage to the product due to condensation
If the product is moved from a cold environment to a warm environment, condensation may form
in the product.
• When there is a large temperature difference, wait for the product to reach room
temperature before connecting to the voltage supply.
• Make sure the product is dry.
Additionally required material (not included in the scope of delivery):
