Signal voltage and control voltage of the PacDrive units are <33 V.
In this range the specification as PELV system according to IEC
364-4-41 includes a protective measure against directly and
directly touching dangerous voltages by means of a "safe
separation" from the primary to the secondary side in the plant/
machine. ELAU urgently recommends to execute the plant/
machine with safe separation.
DANGER!
High voltage due to wrong connection!
Life hazard or risk of serious injury!
 Only units, electric components or cables with a sufficient safe
separation of the connected power supplies according to EN
50178 / 1998 (equipment of high-voltage systems with electronic
operating means) may be connected to the signal voltage
connections of these components.
 Make sure that the existing safe separation is retained
throughout the entire current circuit.

When using ELAU components in systems that do not include a
safe separation as a means of protection against directly or
indirectly touching dangerous voltages, all connections and
contacts (e.g. MAx-4, Sub-D connector, serial inerface) that do not
comply with protection class IP2X must be permanently covered.
The cover or device connection must be such that it can only be
removed with the help of a tool. The protective measure must be
observed on all connected devices.
