When using the M-Series PLC, please observe the precautions provided below.
Using the power
Please use the voltage specified in the Manual. Incorrect voltage will lead to false action or burning
⚫
damage to the equipment.
If the number of the module being connected exceeds the current rating of the power module, you
⚫
may not be able to start the CPU module or other modules.
Please use the designated power source and then supply the power according to the specified voltage
⚫
and frequency rating. Special attention should also be given to the location subjected to unsteady
power supply, as incorrect power supply may result in false action.
Before starting any of the following operations, be sure to disconnect the PLC power; or it may lead
⚫
to false action or electrocution injury.
(1) When installing or dismantling power module, I/O module, CPU module or any other type of
module.
(2) When connecting cables or executing the system wiring.
(3) When connecting or disconnecting the connector.
When using the power module, be sure to observe following precautions.
⚫
(1) The voltage applied at the equipment output point or the connected load shall not be higher than
the rated specifications established for the power module.
(2) If it is required to put aside the power module for over 3 months, it shall be stored in a cool and
dry location in order to maintain its function at normal status.
(3) If the power module is improperly installed, it will result in the accumulation of heat as to cause the
aging or the damage of the component within. Therefore, it shall be properly connected and you are
also required to use the standard installation method.
Installation
Do not install the PLC at the location near a high frequency noise interfering source.
⚫
Confirm that the terminal board, the connector, the memory card, the peripheral communication wires
⚫
and other buckle-mounted devices are latched in position. Improper latching will result in false action.
After connecting to the adjacent module, the buckle at the top or the bottom must be securely locked
⚫
i.e.,
( properly latched). If failing to lock the buckle tightly, the module may not be able to achieve the
intended function.
