(g) The supply from the power supply control panel as provided by Electrical
Dept. shall be taken to various S&T locations by S&T Dept.
The supply from the power supply control panel shall be extended through
separate MCBs to cabins, LC gates, telecom installations etc, If these are
falling within two km of power supply control panel. For locations which are
at two km or beyond, a separate set of ATs and power supply control panel
shall be provided.

(h) In case of IB Signals, separate set of ATs shall be provided, with
Automatic change over switch.
Note: Please refer to Para No. 20713 of ACTM, Volume-II, Chapter-VII.

(i) DG sets, where installed, shall be provided with push button start/stop
facility. As per site requirement and feasibility, it shall also be possible to
operate remotely.

16.2.2 Non Railway Electrified Area

(a) For Colour Light Signalling (CLS) installations, local power supply shall be
used as main source of supply. In addition, two standby diesel generators
shall be installed. These generators shall be of standard make and of
adequate capacity for reliable and trouble free service.

(b) The output supply of these generators, along with local supply, shall be
brought to the ASM office and connected to auto/manual change-over
panel compatible to RE.
(c) Solar Photo Voltaic System/Solar Panels (approved type) may also be used
as power supply at wayside stations, LC gates in those areas having sufficient
sun light and are not theftprone.

(i) A solar panel consists of a number of modules (Typically 12 V each) which
are connected in series and parallel configuration to provide a specific
voltage and current to charge a battery bank, which in turn supplies
necessary power supply to signalling and telecommunication applications.
(ii) They may be used to charge battery bank of Integrated Power supplies
or may be used in for signal lighting by using invertors. Main
components of solar photo voltaic system are;
 Solar Array
 Battery bank
 Solar charge controller
 Field junction box
 Solar Module Mounting Structure
 Earthing Kit
 Cables
