Installation Guidelines
-
Power Off: Always disconnect power from the chassis before installing or removing the processor module to prevent electrical shock or damage.
-
ESD Protection: Use a grounded wrist strap or similar ESD protection when handling the module to prevent damage to sensitive electronic components.
-
Mounting: Ensure the module is fully seated in the designated slot of the SLC 500 chassis and secured with the chassis retaining screws.
-
Wiring: Use shielded cables for communication connections to minimize EMI interference. Ensure proper routing away from high-voltage power lines.
-
Environment: Install in a clean, dry, and vibration-free enclosure rated for the intended industrial environment.
FAQ
What is the 1747-L553?
It is a high-performance, single-slot processor from the SLC 5/05 series, designed for mid- to large-scale applications requiring Ethernet and RS-232 communication.
What are the key differences from 5/03 or 5/04?
The key difference is the native Ethernet port for faster networking, along with 64K of memory.
Can I swap modules while power is on?
No. Never install, remove, or wire any module while power is applied to avoid electrical hazards and potential damage to the backplane.
