2. Safety notes
Please read the following notes before using this controller. Contact your distributor or dealer for any
doubts or further advice.
This device must not be used in an application where its failure could cause a hazard to human
health or damage to other equipment. Keep in mind that if the device is used in a manner not
foreseen by the manufacturer, the protection provided by its circuits and by its enclosure may be
impaired.
This is a low voltage device. As such, the potential difference between any combination of applied
signals must not exceed, at all times, the supply voltage. Higher voltages may cause a fault and can
be dangerous to human health.
This device has limited protection against transients caused by inductive loads. If necessary, use
external protection devices like fast diodes or, better, specific transient protectors.
The controller outputs pulses with high energy content. The user must be careful to connect the
inputs and outputs correctly and to protect the output wiring and load from unintentional short-
circuits. When the device is switched off, there is still energy stored in the internal capacitors for at
least five minutes.
When operating the controller at the maximum ratings it can get very hot. The controller should be
positioned where personnel cannot accidentally touch it and away from flammable materials. Never
exceed the power ratings stated in the manual.
3. Product end-of-life handling
Observe the following guidelines when recycling this equipment or its components.
Production of this equipment required the extraction and use of natural resources. The equipment
may contain substances that could be harmful to the environment or human health if improperly
handled at the product’s end of life. In order to avoid release of such substances into the environment
and to reduce the use of natural resources, we encourage you to recycle this product in an
