2.2 General Installation Rules
Important: This equipment is to be installed, maintained and serviced by authorized service
persons only.
The authorized installation contractor should comply with the following rules:
• Neatly label cables at both ends.
(For example, labels should include: controller address number/device or reader number)
• Use individually shielded pairs of cables only. All wiring must comply with local, state, and federal
electrical codes and fire codes.
• Obey all national, state, and local electrical and safety codes.
• Obtain any required permits and/or inspections. Contact the local fire marshal for assistance if
necessary.
• Safety of customer personnel is the primary consideration of the installation.
• Neatly dress and tie or lace all wiring in a professional manner.
• Gather together and tape all unused conductors in multiple conductor cables.
• Shield all cabling and terminate properly.
Notes: This is an FCC Class A product. In a domestic environment, this product may cause radio
interference in which case the user may be required to take adequate measures.
Circuit board components are vulnerable to damage by electrostatic discharge (ESD). ESD can
cause immediate or subtle damage to sensitive electronic parts. An electrostatic charge can
build up on the human body and then discharge when you touch a board. A discharge can be
produced when walking across a carpet and touching a board, for example. Before handling
any board, make sure you dissipate your body’s charge by touching ground. This discharges
any static electricity build-up.
2.3 Signal Transmission
• Where practical, keep cables well separated from each other. Separate power cables from signal cables.
• Keep the break-out at the ends of signal cables as short as possible.
• Ground all shield drain wire(s) at the M5 controller using the grounding studs provided outside the
cabinet enclosure.
• For communication cables between controllers, ground shield to the upstream controller only.
Note: Do not ground both cable ends.
