When installing the KSU and station instruments, allow a sufficient
margin for error in case of air conditioning failure, routine
maintenance, plant shutdown, etc. As a general rule, if conditions are suitable for office
personnel, they are also suitable for KSU and terminal equipment operation. A properly
controlled environment will help to extend the operating life of the equipment.
The following statements are from UL 1459, a product safety specification governing telephone

• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

2.3 Tools and Supplies

Assemble the correct supplies and tools to install the Comdial DX-80.
• Use UTP (Unshielded, Twisted-Pair) three or four pair (recommended) cable to run from the
MDF to all extension terminals (DETs, DSS consoles, and analog devices). DETs only need one
twisted pair to operate. Additional pairs are always recommended to allow for future potential
uses.
• Six conductor modular jack assemblies for all station instruments (recommended).
• Standard punch-down terminal blocks (66M1-50 type) as required.
• Four or six conductor crimping modular plug assemblies for each port interface.
• AC voltage surge/spike protector.
• Standard telephone hand tools and mounting hardware for the KSU(s), MDF backboard, punch-
down terminal block(s), modular jack assemblies for CO lines, etc.
