4.1. Safety Statements
Caution: Danger of electric shock. The device may be connected to hazardous voltages. Switch to power-
off state before working on the device.
Caution: Danger of electrostatic discharge. Electronic components are sensitive to electrostatic discharges
that might damage the device. Protect the device from electrostatic discharges by wearing an electrostatic
wristband connected to a grounding terminal.
Caution: Interruption of data transmission. Data transmission will be interrupted during any work on the
transmission line and/or deactivation of the power supply. Make sure that that any work will only be
carried out on inactive lines (without data transmission) or during quiet times to reduce interference to live
systems.
Caution: Danger of damage to devices or service interruption. Access by unauthorized third persons may
cause damaged devices and/or interrupted services. Make sure that subracks are only installed in lockable
locations.
Caution: Danger of overvoltage. During faults, dangerous unprotected voltages may be present. Ensure
sufficient grounding of the housings, i.e. by connecting the grounding contact.
