Safety Review
Certain precautions should be taken when using electrical products. Please observe the safety hints by
reading the manual and obtaining qualified help if necessary to adhere to the precautions.
1. Always use a properly grounded power supply cord with this product. Please do
not defeat the ground pin on the mains plug. This connection provides earth to the chassis and
signal grounds inside the device for clean and quiet operation. The “Grounding and interface”
section can help the user/installer clear up a buzz problem if one develops.
2. Avoid high temperature operation in equipment racks by providing air
circulation. The number one killer of electronic gear is HEAT. Vented rack panels may look like
wasted space to an interior decorator, but they look like beauty to a technician or equipment
designer! If the front panel is hot, it is roasting inside the box.
3. Avoid areas of high magnetic fields. The steel chassis of 2Bus LT is designed to
shield the circuits from EMI and RFI (magnetic and radio interference). When installing
equipment in racks, it is prudent to put power amplifiers and large power supplies at least several
rack spaces, if not in a different rack, away from equipment that deals with low level signals.
Separation of high level and low level equipment can pre-empt trouble caused by heat and EMI.
4. Care should be taken to avoid liquid spills around equipment. If a spill occurs,
please shut off the gear and disconnect the mains. A qualified technician should investigate
accidents to prevent further equipment damage or personnel hazards caused by spills.
5. If one is uncomfortable with opening gear and changing jumpers or making
adjustments, please seek qualified help if necessary.
6. If adjustments or jumper changes are required, please disconnect the mains plug
before opening the top. Dropped screws or tools on a live circuit board can manifest themselves
as burn marks and smoked components. While we feel your pain, (been there) subsequent damage
is not covered by the warranty.
