WARNING
• Electric work must be performed by an authorized technician. Improper wiring work may result in electric
shock or fire.
• Turn off the power supply before performing wiring work.
CAUTION
• To avoid damage to the terminal block, do not connect an AC power supply (100-240VAC) to the M-NET
transmission terminal block.
To prevent overheating and fire, properly fix the cables in place so that the weight of the cables will not strain the
connectors.
Improperly connected cables may break, produce heat, and cause smoke or fire.
