Safety Instructions - Warnings and Cautions
SAFETY
1. Read and follow all warning notices and instructions marked on the product or included in
this manual
2. Do not allow anything to rest on the power cord and do not locate the product where
persons could step or walk on the power cord.
3. When installed in the final configuration, the product must comply with the applicable
Safety Standards and regulatory requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies and inspection authorities to
ensure compliance.
4. No hazardous RF radiation is emitted from the equipment. Measured at the surface of
the CRU radome, when transmitting, the maximum total power radiated from the CRU is
0.01% of the UK National Radiological Protection Board basic restriction per kg. of body
part.
WARNING - HAZARDOUS VOLTAGES
On AC installations, hazardous voltages exist. Use caution when verifying or working with
AC power. Remove metal jewellery that could come into contact with AC power.
On DC sections, short circuiting the low voltage, low impedance circuits can cause severe
arcing that may result in burns or eye damage. Remove rings, watches etc. to avoid shorting
DC circuits.
Electro-Static Discharge ESD
Electro-Static Discharge. Many circuits contain devices which are susceptible to damage
from high impedance voltage sources. To avoid such risks always follow anti-static
procedures where marked.

NOTE
Airspan products do not contain hazardous substances (as defined in UK ‘Control of
Substances Hazardous to Health Regulations 1989’, and the ‘Dangerous Substances
Regulations 1990’). At the end of any Airspan product’s life cycle, the customer should
consult with DSC to ensure that the product is disposed of in conformance with the relevant
regulatory requirements
The Symbol on an Airspan product signifies that it has been certified according to the
EMC directive 89/336/EEC. The product fulfils the requirements according to the following
standards:
EN50082-1 for Immunity.
EN55022 Group 1 Class A for the Central Terminal Emissions.
EN55022 Group 1 Class B for the Subscriber Terminal Emissions.
NOTE
The Subscriber Terminal equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules.

INTRODUCTION
1. Purpose of Document
This document describes the installation and commissioning of the ACC AS4000™
Central Terminal (CT) Rack and associated shelves to AS4000 specifications. This
document covers new rack installations and the incremental addition of modem
shelves.
2. Prerequisite skills
Personnel installing and commissioning the Airspan products must have a basic
knowledge of telephony and radio communications, and have experience in installing
telecommunications products. ACC provides a range of comprehensive training
courses specifically aimed at providing operators/users of Airspan products with the
prerequisite skills to install, commission and or maintain the product. The courses can
be tailored to provide the level of training required by the operator/user.
This manual is intended for use by persons familiar with the AS4000 product having
attended the ACC CT Installation and Commissioning training course prior to
performing the procedures in this practice.
