Installing Base Stations
Before installing a Base Station, verify the position as documented in the
Meridian Compani on Programming and Provisioning Record.
Installatio n guidelines
Each Base Station must be installed within 1200 m (TCM
wiring length) of the Meridi an Com panion system.
Consider the following point s when installing Base Stations or Base Stat ion
plug-top power supplies:
• Ensure that the installation complies with your local electrical code.
ATTENTION!
• Install Base Stations indoors where there is no condensation and the
temperatur e r emains between 0°C and 50°C, preferably between 15° C
and 35°C.
• Instal l all Base St ations wit hin 1200 m (wiri ng length) of th e Meridian 1
system.
• Do not p ositi on Base S tations on la rge concrete o r ma rble colu mns. Base
Statio n s mu s t b e at lea st 1 m fr om such col u m n s. Lo c ate all Bas e
Stations at a cell center on the same side of such columns.
• Position Base Stations on ceilings, or upright against wall s cl ose to the
ceilin g on s u rfac es with th e s ame mate r ial compo s i ti o n .
• Allow a clearance o f at least 9 cm between the Ba se Stations and
surroundi ng objects, excluding other Base Stations (see Figure 2 on
page 14).
• Pos i ti o n al l th e Base Stations at the sa me cell center a maximum o f
1.5 m apart, with a minimu m of 9 cm between the Bas e Station s ( see
Figure 2 on page 14).
• Do not position Base Stations in ducts, plenums, o r hollow spa ces used
to transport environmental air.
553-3601-220 Standard 4.00 November 1998
Installing the hardware Page 13 of 206
• Position Base Sta tions away from where a port able is used in an office
area b y at lea st the amount sho wn in Table 1. Installing the Base Stati ons

Minimum distance between
office areas and Base Stations
• If powering with plug-top power, position the Base Station within 4 m
of an AC outlet, since the plug-top power supply has a 4-metre cord.
Keep these points in mind:
— the power supply must be lo cated in an area acces sible to a prope rly
grounded AC outlet
— the input plug is part of the po wer supply (the only way to remove
power is to disconnect the power supply)
— if you must install a new AC outlet to accommodate the power
supply, ensure that the AC outlet is mounted with sufficient
clearance to plug the power supply
Powering a Base Station
Base Stations can be powered by plug-top power supplies or remote powe r
interconn ect units. See “Insta lling remote powe r interconnect units” or
“Mounting a Base Station plug-top power supply” for your configuration.
— if more than one Bas e Stat ion is in st alle d at a cell cen ter, ens ur e that
each plug-top power supply has a separate AC outlet

Mounting a Base Station
Base Stations can be mounted on a wall or on a ceiling (when mounting on a
wall, i nstall it with the cover at t he bottom, as s hown in F igure 9 on pag e 21).
Allow for the following clearance around the Base Station.

Installing remote power interconnect units
Figures 6 and 7 illustrate two possible configur ation options using a remote
power interconnect (RPI) unit.
Figure 6 shows a configuration that is appropriate for a small installation
where ther e is no main distribution f rame (MDF). In this case, the RP I MDF
capabili ties provid e the connections between the Meridian 1 system, Base
Station power, and Base Stations. Essentially, the RPI unit functions as a
distribution panel. This configuration can also be used if the existing MDF is

full or if the customer wants to keep the wiring separate from the other
telephone set wiring.
Note: The polarity of the TCM connections is not important. If two power
pairs ar e brought in, they must be connected with the same polarity to
the termina tion board.
WARNING!
When using two po wer pairs, ensure
they are connect ed w ith the same
polarity.
