204 Planning for installation
Routing the cables
See chapter
Planning the electrical installation
in the drive hardware manual. Obey
especially these rules:
• When using redundant signaling, take care to avoid common cause failures in the
cables. This can be done by routing the two channels through two well-apart
routes, or by protecting the cabling appropriately, for example by using double-
shielded cables.
• Never mix 24V-level signals with non-ELV-signals or power feeds in the same
cable.
• Safety Related Electronic Control System (SRECS) signal cables for the
individual channels must be routed separately from the other channels at all
positions or sufficiently shielded.
• SRECS signal and electrical energy power cables must be separated at all
positions or sufficiently shielded.
• Cross-connection between the channels of the subsystem must be prevented.
• Signal paths must be physically separated (for example, separation in wiring).
