5.1.3 Standards and certifications
NOTE
You find detailed information to the standards and certifications in the
reference manual "SIMATIC S7-400 Automation System Module Data,
chapter 1, section: Standards, certificates and approvals".
5.1.3.1 FM 458-1 DP outputs
!
DANGER When the equipment is powered-up or powered -on, the outputs
have undefined statuses while the power supply voltages are
running-up. This fact must be taken into account when designing
the system.
5.1.3.2 Professionally-trained and knowledgeable personnel
Only professionally-trained, knowledgeable personnel may configure,
install, commission and operate FM 458-1 DP.
5.1.3.3 Connecting external voltages
If external voltages (e. g. pulse encoders) are connected to FM 458-1 DP
inputs, which are supplied from an external power supply, then this
external supply must also be shutdown when the FM 458-1 DP power
supply is shutdown or fails.
5.1.4 Mounting and operation
The subracks for the S7-400 are designed for wall mounting, mounting
on frames and for installation in racks and cabinets. The retaining
dimensions are in conformance with DIN 41 494.
In the validity area of UL/CSA and the EC Directive 2006/95/EC (Low
Voltage Directive), it is necessary to install the subrack in a cabinet, an
enclosure or an enclosed operating room so that the regulations for
electrical safety are fulfilled (refer to the SIMATIC S7-400 Automation
System/M7-400 Module Data Reference Manual, Chapter 1).
The subrack must be installed so that the ventilation slots of the module
point up and down.
All of the modules must be inserted in the subrack left-justified in order to
obtain the optimum EMC-compliant design. It is not permissible that there
are gaps between the individual modules.
The terminal blocks must be inserted so that the ventilation slots point up
and down.
