■

Connection to external equipment

* Wire the cables so that the user does not touch the power supply directly.
* On the equipment side, use a basically insulated power circuit and place it in a location where the user cannot touch it.

●

NOTE

• Do not connect the device directly to the primary side of the power supply.

Be sure to install a circuit breaker or all-pole isolating switch (with a contact breaking distance of at least 3 mm) on the 
primary side of the power supply.

• Fasten the screws to the terminal with torque of 0.5 N•m.
