Data cables
NOTE
Layout of data cables
•
Use shielded data cables with twisted-pair wires.
•
The possible cable length between the device and host computer depends on:
°
The chosen physical version of the host interface
°
The data transmission rate set in the device
For further information, see "Wiring the data interface", page 46.
•
Implement the shielding design correctly and completely.
•
To avoid interference, always use EMC-compliant cables and layouts. This applies,
for example, to cables for switched-mode power supplies, motors, clocked drives,
and contactors.
•
Do not lay cables in parallel with voltage supply cables or motor cables in cable
channels over longer distances.
Conditions for specified enclosure rating
To ensure compliance with the specified IP67 enclosure rating of the device, the follow‐
ing requirements must be met. If these requirements are not met, the device does not
fulfill any specified enclosure rating.
•
The joint side cover for the USB interface and the memory card slot is placed
against the device and screwed on tight.
•
The cables plugged into the electrical M12 and M8 connections must be screwed
tight.
•
Any M12 and M8 connections that are not being used must be sealed with protec‐
tive plugs or caps, depending on type. These plugs or caps must be screwed tight
(as in the delivery condition).
The same also applies to the EMC requirement (ESD) according to CE.
NOTICE
The type label on the lower side of the device contains a pressure equalizing mem‐
brane. If damaged, water and dust leaks could occur.
Positions of the individual elements see "Device view", page 15
NOTICE
The device can, if necessary, be operated for a short time without the side cover to per‐
form the following tasks:
•
Inserting or removing the optional memory card
•
Temporary use of the USB interface as a servicing interface
During this time, protect the device against moisture and dust.
