RECAUTIONS
• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the SX5L communication terminals.
• All SX5L modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe
provision to the control system using the SX5L in applications where heavy damage or personal injury may be caused in
case the SX5L should fail.
• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:
• Turn off the power to the SX5L before starting installation, removal, wiring, maintenance, and inspection of the SX5L.
Failure to turn power off may cause electrical shocks or fire hazard.
• Special expertise is required to install, wire, program, and operate the SX5L. People without such expertise must not use
the SX5L.
• Emergency stop and interlocking circuits must be configured outside the SX5L. If such a circuit is configured inside the
SX5L, failure of the SX5L may cause disorder of the control system, damage, or accidents.
• Install the SX5L according to the instructions described in this user’s manual. Improper installation will result in falling,
failure, or malfunction of the SX5L.
• The SX5L is designed for installation in a cabinet. Do not install the SX5L outside a cabinet.
• Install the SX5L in environments described in this user’s manual. If the SX5L is used in places where the SX5L is sub-
jected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks, then
electrical shocks, fire hazard, or malfunction will result.
• The environment for using the SX5L is “Pollution degree 2.” Use the SX5L in environments of pollution degree 2 (accord-
ing to IEC 60664-1).
• Prevent the SX5L from falling while moving or transporting the SX5L, otherwise damage or malfunction of the SX5L will
result.
• Prevent metal fragments and pieces of wire from dropping inside the SX5L housing. Put a cover on the SX5L modules dur-
ing installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
• Make sure of safety before starting and stopping the SX5L or when operating the SX5L to force outputs on or off. Incorrect
operation on the SX5L may cause machine damage or accidents.
• Connect a protective ground to the cabinet containing the SX5L using a wire of UL1007 AWG16 (grounding resistance
100 Ω maximum).
• Do not disassemble, repair, or modify the SX5L modules.
• When disposing of the SX5L, do so as an industrial waste.
