10/40 Safety instructions
Bosch Rexroth AG, VT-VSPA2-1-2X/V0/T., RE 30110-B/11.2012
High electrical voltage by incorrect connection!
Danger to life, risk of injury caused by electric shock.
▶ All connections and terminals with voltages between 0 and 50 Volt may only be
connected with devices, electric components and lines with a protective extra-
low voltage (PELV).
▶ Only connect voltages and electric circuits provided with a safe isolation from
dangerous voltages. Safe isolation can be achieved for example with isolation
transformers, safe optocouplers or mains-free battery operation.
High voltage!
Risk of injury.
▶ Only wire and plug the analog amplifier card in de-energized state.
Stroke of lightning!
Risk of uncontrolled machine movements.
▶ An incorrect earthing concept or lack of equipotential bonding may lead to dam-
age to the electronics. Provide for equipotential bonding for the device.
Failures and errors in the control circuits or the energy supply!
Risk of uncontrolled machine movements.
▶ Comply with safety instructions according to EN ISO 13849 or IEC 62061.
Hot surfaces!
Risk of burning.
▶ System parts may become hot during operation. Allow the system parts to cool
down before touching them or wear protective gloves.
Fault currents and short-circuits!
Impairment of safety and malfunctions.
▶ The environment must be free from electrically conductive contamination (acids,
bases, corrosive agents, salts, metal vapors, etc.) and the device must not be
exposed to these substances. Rule out any deposits according to protection
class IP.
