f)
The location should have adequate accessibility, space and lighting for future servicing and
should consider the need for future expansion.
g)
The site should be away from radio transmitting equipment, arc-welding devices, copy machines,
and other electrical equipment capable of generating electrical interference. The system should
be protected from flooding and heavy machinery as well as excessive dust and vibration.
3.2.2 Backboard Installation
A wooden backboard is recommended for all installations and must be installed when the location has
masonry or plasterboard walls. A 0.5-inch plywood material is sufficient for most installations. The
backboard should be mounted at a convenient height, about 1 meter above the floor, and be bolted in a
number of places to distribute the weight of the system.
Space should be available on the bottom side of the backboard for the MDF and/or other MDF and for
optional equipment such as a music source and PFTU, etc.
3.2.3 Verify On-Site Equipment
Once the equipment installation site has been identified and a dedicated AC outlet, earth ground, and
lighting and ventilation are available, verify that all equipment required is on-site and has not been
damaged during shipment. Assure there is no shipping damage. Note that a mounting template is packed
with KSU and this template will be required later in the installation. Check that the type and quantity of
boards received is correct and optional equipment and a Power Line Surge Protector are on-site. Note
that the individual boards should not be unpacked at this time.
If any equipment is damaged or missing, notify appropriate personnel to correct the situation.
3.3 KSU Installation
ARIA-130 system consists of two KSUs, 1st and 2nd KSU. The 2nd is used for expansion KSU.
Caution:
1.
Installing 1st and 2nd KSU together on the brick wall can cause the connection between
Basic and Expansion KSU to be unstable. So we recommend that two KSUs should be
installed on the flat wall.
2.
Powering on when KSU1 and KSU2 are both installed: -
−
Power on sequence: power on the 2
nd
KSU first and then the 1
st
KSU
−
If the 1
st
KSU is powered on before the 2
nd
KSU, then the MPB must be reset.
