LTP-8X optical line terminal
Chapter 7.
Safety precautions and installation procedure
Introduction
This chapter describes installation of the terminal into a rack and connection to a power supply.
7.1
Safety requirements
General
Any operations with the terminal should comply with
Safety Rules for Operation of Customers' Electrical
Installations
.
Operations with the terminal should be carried out only by personnel authorised in
accordance with the safety requirements.
1.
Before operating the terminal, all engineers should undergo special training.
2.
The terminal should be connected only to properly functioning equipment.
3.
The terminal is to be operated 24/7 provided the following requirements are met:
a.
ambient temperature from +5 to +40 °C;
b.
relative humidity up to 80 % at +25 °C;
c.
atmosphere pressure from 6.0×10
4
to 10.7×10
4
Pa (from 450 to 800 mm Hg).
4.
The terminal should not be exposed to mechanical shock, vibration, smoke, dust, water, and
chemicals.
5.
In order to avoid components overheating which may result in terminal malfunction, do not
block air vents or place objects on the terminal.
6.
Prior to connecting the terminal to a power source, ensure that the terminal case is grounded
with an earth bonding point. The earthing wire should be securely connected to the earth bonding
point. The resistance between the earth bonding point and earthing busbar should be less than 0.1
Ohm.
7.
PC and measurement instruments should be grounded prior to connection to the terminal. The
potential difference between the terminal case and the cases of the instruments should be less than 1 V.
8.
Prior to turning the terminal on, ensure that all cables are undamaged and securely connected.
