Safety Notes
2.6
Installation
The units must be installed and cooled according to the regulations and specifications
in the corresponding documentation.
Protect the DRC drive units from improper strain.
The following applications are prohibited unless explicitly permitted:
• Use in potentially explosive atmospheres.
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, radiation, etc.
• Use in non-stationary applications that are subject to mechanical vibration and shock
loads as stated in the documentation for DRC drive units.
Important: DRC drive units and corresponding mount-on parts must not protrude into
footways.
2.7
Electrical connection
Working on live parts of DRC drive units is not permitted.
The drive is operated as a generator due to the kinetic energy of the system/machine.
Secure the output shaft against rotation before opening the wiring compartment.
Electrical installation must be carried out in compliance with pertinent regulations (e.g.
cable cross sections, fusing, protective conductor connection). For any additional infor-
mation, refer to the applicable documentation.
You find notes on EMC-compliant installation, such as shielding, grounding, arrange-
ment of filters and routing of lines, in the documentation of the DRC drive units. The
manufacturer of the system or machine is responsible for maintaining the limits estab-
lished by EMC legislation.
Protective measures and protection devices must comply with the regulations in force
(e.g. EN 60204-1 or EN 61800-5-1).
2.8
Safe disconnection
DRC drive units meet all requirements for safe disconnection of power and electronics
connections in accordance with EN 61800-5-1. All connected circuits must also satisfy
the requirements for safe disconnection to ensure reliable isolation.
