1.2 Occupational Health & Safety / Work Health and Safety Warnings
1.2.1 General Caution
Only a suitably qualified person should be allowed to install and commission this equipment after comprehending and
becoming familiar with all the safety and installation instructions contained in this User’s Manual. It will be assumed that a
qualified person will have a fundamental knowledge of the objectives and use common sense where safety warnings are not
necessarily explicit.
The unit is heavy and appropriately considered a two-man lift. Handles are provided to the front of the equipment to assist in
removal of the DSPbR® from the packaging and during installation.
On unpacking the equipment, familiarise yourself with equipment, reading and following all warning labels attached to the
equipment. Please ensure that the warning labels are kept in a legible condition and replace if necessary.
Ensure all general, regional and site-specific installation and safety regulations are adhered to when working on high voltage
installations, as well as regulations covering use of tools and personal protective equipment.
It is the responsibility of the network operator or service provider to have in place and implemented a legally compliant
Occupational Health and Safety (OHS) / Work Health and Safety (WHS) law as applicable, detailing prevention measures to
avoid health hazards which may be associated with radiation from the antenna(s) connected to this equipment. Please ensure
familiarisation and compliance to country specific regulations on RF exposure.
Ensure all adjustable repeater settings comply with intended use and applicable National, State and Regional regulatory
requirements.
Ensure that access to this equipment is restricted to qualified personnel only.
There is no On/Off switch on the unit –it becomes active as soon as AC or DC power is connected via the provided AC
mains cable or DC power source.
Do not allow the DSPbR® or any associated equipment to become wet or to be subjected to a corrosive environment, humidity or
temperatures outside the specified operating ranges.
Do not operate the unit near any flammable substances or in a flammable atmosphere.
Ensure that all RF termination connectors are fully mated and hand tightened.
Use this equipment only for the purpose specified by RF Industries Pty Ltd. Do not carry out any modifications or attempt
any module repairs. All modules in this DSPbR® are not intended to be field repairable and should be returned to RF
Industries for service or repair.
When engaged in upgrading or maintaining the DSPbR, please note that the RF Front End and RF Back End modules are “Hot
Swappable” accessible from the rear of the sub-rack frame using a suitable module extraction tool. Should an upgrade or
maintenance require any further deconstruction or access to the equipment, the AC or DC power supply should be disconnected
and isolated.
