DLA200 Dual Line Amplifier Unit

Issue 1.00 DLA200 Dual Line Amplifier Units Page 2

INTRODUCTION

The DLA200 units are able to power 2 MLA Amplifier units.

The DLA200 units are housed in 19 inch 1'U' high chassis, suitable for rack mounting. They are 400 mm
deep and may be fitted with rack slides if required.

EMC AND SAFETY

EMC

The DLA200 units have been designed to comply with the following standards;

Emissions : EN 55022 Class B; Limits and methods of measurement of radio interference

characteristics of Information Technology Equipment.

Immunity : EN 50082 Part 1; Generic immunity standard, part 1: Domestic, commercial and light

industrial environment.

The equipment must be operated with its lid on at all times. If it is necessary to remove the lid for routine
servicing or fault finding then it is essential that the lid is fitted back correctly before normal operation.

For the Alarm and Remote Control data interfaces all 'D' type connectors must have grounding fingers on
the plug shell to guarantee continuous shielding. The back-shells must comply with the requirements of
VDE 0871 and FCC 20708, providing at least 40 dB of attenuation from 30 MHz to 1 GHz.
Connecting cables must be of the shielded

Operation of the equipment in a non standard manner will invalidate compliancy to these
standards.

Safety

To ensure safety of operator the DLA200 units have been designed to comply with the following safety
standard;

EN 60950 Safety of information technology equipment, including electrical business machines.

Before operation the user must ensure that the installation complies with the information given.

The equipment is designed to operate in a static 19 inch rack system conforming to IEC 297-2. Operation
of the equipment in transportable vehicles equipped with the means of providing a stable environment is
permissible. Operation of the equipment on board vehicles, ships or aircraft without means of
environmental conditioning will invalidate the safety compliancy; please contact the factory for further
advice. Operation of the equipment in an environment other than that stated in the specifications will also
invalidate the safety compliancy. The equipment must not be operated above 2000 metre altitude,
extremes of temperature; excessive dust, moisture or vibration; flammable gases; corrosive or explosive
atmospheres.

Installation

The equipment is classified in EN 60950 as a pluggable equipment class A for connection to the mains
supply, as such it is provided with mains inlet cords suitable for use in the country of operation. In normal
circumstances they will be of an adequate length for installation in the rack. If a mains cord proves to be

too short then any replacement must have a similar type fuse (if fitted) and be manufactured to similar
specification: check for HAR, BASEC or HOXXX-X ratings on the cable. The connector ends should be
marked with one of the following : BS1636A (UK free plug 13 amp); BSI, VDE, NF-USE, UL, CSA,
OVE, CEBEC, NEMKO, DEMKO, SETI, IMQ, SEV and KEMA-KEUR for the IEC 6 amp free socket.
Schuko and North American free plugs must have similar markings.

The installation of the equipment and the connection to the mains supply must be made in compliance to
local or national wiring regulations for a category II impulse over voltage installation. The positioning of
the equipment must be such that the mains supply socket outlet for the equipment should be near the
equipment and easily accessible or that there should be another suitable means of disconnection from the
mains supply.

The equipment is designed to operate from a TN type power supply system as specified in EN 60950.
This is a system that has separate earth, line and neutral conductors. The equipment is not designed to
operate with an IT power system, which has no direct connection to earth.
