5 Installation
This section describes the physical and electrical installation of the Night Scan Powerlite, Night
Scan Powerlite Xtreme, and Night Scan HDT and provides the general procedures that must be
followed to ensure a successful installation. Be sure to read and understand the entire installation
procedure and the Safety Summary Section 1 before beginning installation.
5.1 Mounting Location Requirements
The following factors must be included when selecting an appropriate mounting location.
1. Your system is designed to withstand adverse weather conditions, however it cannot be
submerged in water. If the system is mounted in a well, provide adequate drainage. A
minimum of four 1 inch (25mm) diameter drain holes (one per corner) are recommended.
2. Ensure that the mast base and saddle are on a flat surface and in the same plane. The
Stowed Limit Switch is set at the factory based on a level surface. If the system is not level,
these switches may need adjusted as described in Section 7.5.3.
3. The installed elevation of the bottom of the mast base shall be at least 2.7 meters (8.8 feet)
above ground level to prevent reach of upper extremities during operation. Alternatively,
lower elevations are permitted if the mast is properly guarded by the installer or offset
towards the middle of the roof with reach limited by vehicle structure to prevent contact with
the mast during operation.
4. It is important that both the base and the saddle be securely mounted to a sturdy roof or
platform which will not overturn during operational loading of the mast. The surface must be
reinforced to withstand the load at the different points on the mast that can be expected
during operation as shown in Figure 5-1. These are maximum load estimates placed
downward and sometimes upward on the vehicle top by the mast. Note the loading is
reduced for the 2.3 model (see TP-4602001).
