2 General safety instructions
You must follow the safety instructions:
• National and international directives and regulations must be followed for assembly,
commissioning, operation and period tests, in particular the Machinery Directive
2006/42/EC, safety rules and country-specific safety regulations.
• The manufacturer and operator of the machine / system must coordinate and observe
all applicable safety regulations with the responsible authorities on their own respon-
sibility.
• Detailed instructions for commissioning and tests are described in chapter 5.
2.1 Installation requirements
For applications with the device, observe the following guidelines on electrical installation.
• Switch cabinet assembly, protection at least IP54.
• Implement wiring according to EN 60204-32.
• The load sensor cable must be shielded. Connect the shield to earth potential.
Observe the information in the chapter "Installation".
• The fuse may not exceed the value in the table "Technical data".
NOTICE
Sensor cables must be installed separately of main power cables, e.g. in spatially sepa-
rate ducts or bundles.
2.1.1 Protective conductor
With a missing protective conductor, an electric shock hazard exists. Material damage,
severe injuries or death can result.
➢ Connect the external protective earth system (PE) close to the terminals of the
phase conductor using a protective conductor for each mains connection.
Without a protective earth connection, malfunctions can arise during operation. The
protective earth connection facilitates protective equipotential bonding for protection
against electric shocks, as well as functional equipotential bonding for the avoidance of
electrical interference effects on electronic systems.
