Cautions for UTP installation
(a) UTP cable should be satisfied the characteristics of category 5.
(b) Do not access Max. tension strength of the cable during a period of wiring processing.
(c) Do remove only the length of wiring, do not damage the insulator for removing covering (Sheath).
(d) Keep suitable distance between EMI source and UTP cable during the period of installing UTP cable.

3.2.3 Cautions for system and network connection
(1) IP address should be different including this module. If not, normal communication is not available.
(2) Set each exchange number differently for using HS link service.
(3) Use specified communication cable. Other cables may occur communication trouble.
(4) Check disconnection or short circuit of communication cable before installation.
(5) Do tighten communication cable connector.
(6) If cable connection is not stable, it may occur some severe trouble of communication.
(7) Do wiring processing of communication cable separately from power supply line or inductive noise.
