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.
D-sub 9-pin (female)

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.
