750-527 4DO 30V AC/DC 2.0A SSR
Do not exceed the maximum total current for I/O modules (5 VDC) via data
contacts!
The maximum permissible total current for internal system supply of the I/O
modules may not be exceeded. The permissible total current is specified in the
technical data of the head station and power supply. The data contacts for
internal system supply can be damaged and the permissible operating
temperature can be exceeded by higher values.
When configuring the system, do not exceed the permissible total current. If there
is a higher power requirement, you must use an additional supply to provide the
system voltage (5 VDC)!
Ensure proper contact with the DIN-rail!
Proper electrical contact between the DIN-rail and device is necessary to
maintain the EMC characteristics and function of the device.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts).
Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for
handling devices/modules.
Clean only with permitted materials!
Clean housing and soiled contacts with propanol.
Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.
