2.1 BL-700 Connections

This section describes connections when a KEYENCE power supply unit is not

used.

2.1.1 Connector pin assignment

The BL-700 connector has the following pin assignment.

2.1.2 Power supply connections

• Be sure to match the polarities of the power supply when soldering the

connections. Reversing the polarities will damage the unit.

• Make sure that the power supply provides a stable 5 VDC ± 5%. If the

power supply does not function in the above range, it can damage the unit.

• Do not extend the power cable. A long power cable can cause a voltage

drop, preventing the BL-700 from starting properly.

Note: • Use the power supply that provides Class 2 output defined in NFPA 70

(NEC: National Electrical Code) when using this product as an UL certified

product.

• Use the Limited Power Source defined in UL/IEC60950-1 to comply with UL/

IEC60950-1.
