HARDWARE CONFIGURATION AND ASSEMBLY
Rule 2: Prop
er wiring
Separate the cabling into groups (high-voltage lines, power supply lines, signal
lines, ground wiring, data lines etc.).
Run the high-voltage lines and ground wiring or data cables in separate channels
or bundles.
Run measurement lines as close to grounding surfaces as possible (e.g. support
beams, metal rails, cabinet panels).
Rule 3: Fixed cable shielding
Ensure that the cable shielding is connected properly.
Use shielded data lines only. The shielding must be fastened to ground using a
large surface area on both ends.
The shielding of measurement lines must be fastened to ground on both ends.
Run cable shielding directly under the SIWAREX FTC on the shielding channeling.
The shielding is to be run to the connection terminal.
The connection between the shielding rail / ground rail and the cabinet /housing
must be low impedance.
Use metallic or metal-plated connector housings for the shielded data lines.
Rule 4: Special EMC measures
All inductivity that is to be controlled should be connected with suppressors.
Use interference suppressed fluorescent lighting or incandescent lamps for
illuminating cabinets or housings in the immediate vicinity of your controller.
Rule 5: Uniform reference potential
Create a uniform reference potential and ground all electrical operational elements.
If potential differences arise or can be expected between components of your
system, install adequately dimensioned potential equalizing lines. For applications
in areas with a risk of explosion, potential equalization is mandatory.
4.3 Assembly on the Profile Rail
When assembling the SIMATIC components and the SIWAREX FTC, the assembly
regulations must be completely fulfilled for the SIMATIC S7.
SIWAREX FTC is assembled in the following steps:
1. Check for whether the SIMATIC bus connector is connected to the left of the
SIWAREX FTC in the module group.
