• Never connect + and - terminals of the power
supply in the reverse directions, to prevent mal-
functions.
• Use regulated 5VDC ±5% power supply. Use of
a power supply exceeding the range may
cause a damage.
• Do not extend the power supply cable.
Otherwise, voltage drop may occur, adversely
affecting operation of the BL-700.
• Use the power supply that provides Class 2 output defined in
NFPA 70 (NEC: National Electrical Code) when using this prod-
uct as an UL certified product.
• Use the Limited Power Source defined in UL/IEC60950-1 to
comply with UL/IEC60950-1.

CAUTION
Input/Output Wiring
z Wiring of timing input
The timing input starts scanning by the BL-700 (turns the laser on).
Use the no-voltage input for the timing input (use the negative logic
when the TTL input is used).
z Wiring for OK/NG output
Use the OK/NG output for checking by comparing with the preset
data (when preset data is not registered, to indicate if a bar code is
read or not).
The NPN open collector output is used.
Wiring for RS-232C
When a personal computer is connected, arrange the wiring as
shown below.

Installation
Operating Environment
This unit is a precision equipment. So, pay attention to the installation
place and avoid the following places:
z Places subject to direct sunshine or temperature exceeding a
range between 0 to +40
qC (32 to 104qF). [between 0 to +50qC (32
to 122
qF) for the exclusive power supply]
z Places subject to relative humidities exceeding a range between
35 and 85% and condensation by rapid temperature changes
z Places subject to corrosive and inflammable gases, salt, iron dust
and lamp smoke
z Places subject to vibration and shocks directly to the BL-700
z Places subject to oil and chemical splashes
z Places subject to strong magnetic field
z Places subject to ambient illumination exceeding the range speci-
