BAPI recommends using twisted pair of at least 22AWG and sealant filled connectors for all wire connections. Larger
gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device’s wiring in the same conduit as AC power wiring. BAPI’s tests show fluctuating and inaccurate
signals are possible when AC power wiring is in the same conduit as the signal lines. If you are experiencing any of these
difficulties, please contact your BAPI representative .
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity and wiring
connections are important to a successful installation. Not observing these recommendations may damage the
product and void the warranty.
