Cooper Bussmann BU-905U-L Wireless I/O Installation Manual

Installing the Power Supply

The unit works with a 9-30Vdc 0.6 Amp CSA certified Class 2 power supply. For use in Class 1 Div 2 hazardous locations, the power supply must be approved for Class 1 Div 2 use.

Warning – Explosion Hazard

Do not disconnect while circuit is live unless area is known to be non-hazardous.

The following table shows the power supply requirements:

Power Supply

BU-905U-L-T

BU-905U-L-R

12V

600mA

250mA

24V

300mA

125mA

The power supply can be a floating supply or negatively grounded.

The transmitter provides a 24Vdc regulated supply for analog loop power. The supply is rated at 35mA and should ONLY be used for powering analog loops.

To install the power supply:

1.Connect the positive lead to Power Supply Input.

2.Connect the negative lead to Ground.

Note: To ensure internal surge protection works correctly, you must earth each unit using the Earth terminal.

-You should connect the module to the same ground/earth point as the antenna mounting to avoid differences in earth potential during voltage surges.

-Do NOT connect the positive side of the supply to Earth.
