supplied with toxic / oxygen SenSmart 3000s not requiring relays, RS-485 Modbus or LCD
backlight. The optional bottom 10-0233 I/O Power Supply board generates voltages needed for
LCD backlight, relays, RS-485 Modbus and Bridge sensor and is required with any of these I/O
functions. The enclosure is equipped with two threaded 3/4 inch NPT conduit fitting outlet and
pre-drilled mounting flanges.
WARNING:
Qualified personnel should perform the installation according to applicable electrical
codes, regulations and safety standards. Insure correct cabling and sealing fitting practices are
implemented. Do not aim the sensor pointing upward. Install the SenSmart 3000 to a wall or
bracket using the predrilled mounting flanges with I.D. 0.25 on 5.5 inch centers (Figure 2-2). If
conduit is rigid and able to support the weight of the SenSmart 3000, the mounting bolts may be
omitted.
CAUTION:
The sensor should never be installed pointing upwards.
