INSTALLATION GUIDE

Before You Begin 
IMPORTANT! Proper installation requires: 
•  Observing safety guidelines 
•  Analyzing the ceiling structure along the 
proposed rail route 
•  Considering space needed to service the rail 
•  Considering space needed to install the 
PowerRail module 
•  Considering distance to nearby lights to prevent 
them from silhouetting the camera location 
•  Determining the location of ceiling suspension 
assembly components, such as M8 threaded 
rods and anti-sway cables 
•  Knowing parts supplied, parts to be purchased, 
and tools and equipment required 
•  Understanding the installation process by 
reading procedures in this guide in detail before 
beginning installation. 
Safety Guidelines 
The rail system must conform with all applicable 
Standards or Codes of Practice pertaining to the 
country or state in which it is to be installed. 
Specifically: 
•  Certified electricians (in accordance with local 
regulations) must be used to install mains power 
cabling and termination. 
•  Licensed machinery operators must be used 
during installation of the system. 
•  A dedicated power circuit equipped with a 6A 
breaker and 30mA differential must be allocated 
to the system. 
•  Exposed and external cables must be placed in 
conduit or sheathed in cable wrap. 
Ceiling Irregularities 
CAUTION: DO NOT mount the rail 
directly to the ceiling. Irregular ceilings 
can distort the rail and damage it as the 
ceiling expands and contracts. 
A Hilti MF C31/8 fast grip system and Hilti MQ-41 
suspension bar (not supplied) may be required to 
attach the rail to ceiling red iron. 
Acoustic Tile Ceilings 
WARNING! DO NOT mount the rail 
structure directly to an acoustic tile 
ceiling; it cannot support the weight. 
Instead, extend threaded rods through 
the tile to a rigid ceiling structure capable 
of supporting the weight. 
Space Requirements 
Allow at least: 
•  60cm (24in) from the ends of the rail to vertical 
surfaces, such as walls to enable the camera 
trolley to be removed and serviced. 
•  50cm (20in) of vertical space above the rail to 
install the PowerRail module. 
•  23cm (9in) from the rail to nearby lights 
-  Because lights can silhouette the dome 
camera, making it visible to people below the 
rail, factor in the installation height of the rail 
to nearby lighting. 
-  Ensure the gap between the rail and the 
lighting system is no more than 5cm (2in) to 
reduce artifacts inside the cowling. 
IMPORTANT! Installing the rail 
perpendicular to a tube-type lighting system 
may cause more artifacts than when it is 
installed in parallel. 
Lay Out the Structure on the Ground 
Lay out the rail system on a piece of paper to 
identify ceiling obstacles along the route, lighting 
that can affect covert operation, and where to place 
the anti-sway cables. 
Anti-Sway Cable Locations 
To prevent the rail from swaying, two anti-sway 
cables angled out no more than 35° from vertical 
are installed at each end of the rail. Additionally: 
•  For rails 9.1m (30ft) or less, one crisscrossed 
anti-sway cable is installed at the center of the 
rail. 
•  For rails 9.1m (30ft) or more, anti-sway 
crisscrossed cables are installed vertical to the 
rail every 15m (49.2ft) as required. 
•  If the last two crisscrossed anti-sway cables 
cannot be separated by 15m (49.2ft), then 
reduce spacing between all crisscrossed cables 
to make them equidistant.
