1.2.4 Wiring Precautions
• Wiring must be performed by qualified personnel.
Wrong or inappropriate wiring may result in fire, product failure, or electric
shock.
• Connect the correct power supply for the required ratings.
Connecting unsuitable power supplies may result in fires.
• Do not allow foreign matter such as cable chips in the Modules or Mounting Bases.
Foreign matter in the Modules or Mounting Bases may cause fire, failures and/
or malfunctions.
• Connect power supplies of the same phases to the common 1 and common 2 of the
AC I/O Module.
If power supplies of different phases are connected, overheating or fire may
occur.
• If using a single-phase AC power supply (100/200 VAC) for driving the loads of the
Relay Contact Output Module, connect power supplies with the same phases to the
common 1 and common 2 of the Module.
If power supplies of different phases are connected, overheating or fire may
occur.
• If using an Output Module, connect a fuse that complies with the load specifications
in series with the load.
A protective fuse is not built into the following Output Modules. If a fuse is not
connected, a fire or damage to the device or output circuits may occur if the load
is short-circuited or the circuit overloaded.
• 100/200-VAC 8-point Output Module: Model No. JAMSC-120DAO083000
• Relay contact 16-point Output Module: Model No. JAMSC-120DRA84300
• If using an Output Module, connect a fuse that complies with the load specifications
in series with the load.
A protective fuse built into the following Output Modules does not protect the
output element. If a fuse is not connected, a fire or damage to the device or out-
put circuits may occur if the load is short-circuited or the circuit overloaded.
• 100/200-VAC 16-point Output Module: Model No. JAMSC-120DAO84300
• 12/24-VDC 8-point Output Module: Model No. JAMSC-120DDO33000
• 12/24-VDC 16-point Output Module: Model No. JAMSC-120DAO34310
• 12/24-VDC 16-point Output Module: Model No. JAMSC-120DAO34320
• 12/24-VDC 32-point Output Module: Model No. JAMSC-120DAO35410
• 12/24-VDC 64-point Output Module: Model No. JAMSC-120DAO36410
