How to connect connectors for CN4 power supply
The power supply (CN4) connector to be connected to the TNU is provided with TNU as standard.

Prepare the power supply cable.
Use the power supply cable with permissible current, making allowance for the usage conditions
(the ambient temperature, number of the core, number of binding wires, and duct storage, etc.)
at 1.25 mm

(AWG16) or below.
* To supply power to multiple units, be careful about the current capacity of the wire rod.
Strip length of core: 9 mm
Terminal treatment:
･
Twist the wires appropriately to prevent them from not spreading.
･
Do not apply solder plating to the core, doing so causes poor contact.
･
Do not twist more than one wire together, doing so may cause a fall.
Wiring and routing:
･
Twist the electric wires of 24 V and 0 V (to exclude noise).
･
Separate the electric wires from strong electric lines (Do not bind them together or place
them in the same duct).
Connect to the connector:
･
Insert the electric wires, pressing the release button of the connector by a tapering screw-
driver. Insert the electric wires to the bottom, and release the release button.
･
Lightly pull the electric wires to ensure that it would not fall off.
･
Once the entire wiring is completed, check that there is no short-circuit caused by two adja-
cent wires.
• Prepare materials used for the power supply cable (the wire rod, and crimping terminal, etc.).
• Unless the connector is fully connected, the product will not operate properly.
