Mitsubishi Electronics #NAME? 사용자 설명서

(Always read these instructions before using this equipment.)

Before using the product, please read this manual, the relevant manuals introduced in this manual, 
standard programmable controller manuals, and the safety standards carefully and pay full attention to 
safety to handle the product correctly.

In this manual, the safety instructions are ranked as "

WARNING" and "

CAUTION".

Note that the 

CAUTION level may lead to a serious consequence according to the circumstances.

Always follow the instructions of both levels because they are important to personal safety.

Please save this manual to make it accessible when required and always forward it to the end user.

● A safety relay module turns OFF all outputs by safety input or a failure of external power supply. 

Create an external circuit to securely stop the power of hazard by turning OFF the outputs.
Incorrect configuration may result in an accident.

● When overcurrent due to such as load short-circuit or load current exceeding the rating flows for a 

long time, it may cause smoke or fire. To prevent this, create external safety circuit such as a fuse.

● Create short-circuit current protection for a safety relay and a protection circuit such as a fuse and 

breaker, outside a safety relay module.

● To inhibit a restart without manual operation after safety function of the safety relay module was 

performed and outputs were turned OFF, create reset start-up circuit using such as a reset switch 
outside the safety relay module.

● The safety relay module may consume excessive current due to a failure. If this occurs, the DC 

power supply connected to the safety power supply part (+24V (SAFETY) and 24G (SAFETY) 
terminals) of the module detects an overcurrent and may shut off the output. To the DC power supply 
connected to the safety relay module, connect only the equipment and the devices that will not affect 
the system even if they are simultaneously stopped due to power-off.

● Use an extension module whose input type is the same as that of the main module. The modules of 

different input types (input P and N types) cannot be connected.
