Safety and Operating Guidelines

Electric Shock Hazard

Touching live parts can result in severe electric shock. Before working on the device or system, switch off the power supply and secure it against reactivation.

Electrostatically Sensitive Components

The device contains electronic components that are susceptible to the effects of electrostatic discharging (ESD). Meet the requirements specified by EN 61340-5-1 to minimize or avoid the possibility of damage. Do not touch electronic components when the supply voltage is connected.

Pressure and Temperature Limits

Medium under pressure can seriously injure people. In the event of overpressure or pressure surges, the device or lines can burst. Before working on the device or system, switch off the pressure and vent or empty the lines. The surface of the device can become hot with fast-switching actuators or with hot media; wear suitable protective gloves.
