2. Safety Instructions
2.1. Positioning Requirements
The options and the conditions for fixing BRIDGE pendant arms are described in the following sections. The pendant arms must be fixed in consultation with the construction manager during installation procedures.
The methods described for the ceiling fixation, gas and power supply are general recommendations and their implementation is to be planned and designed for each individual case by qualified experts.
BRIDGE pendant arms are not suitable for use in potentially explosive areas.
An ambient temperature of 10°C to 40°C must be maintained during operation.
The relative humidity must not exceed 75%.

2.2. Intended Use
BRIDGE pendant arms are intended to carry and position medical devices in operating theaters and intensive care units and to supply these devices with electricity and medical gases. In operating theaters, they also provide the option of evacuation of anaesthetic gases, compressed gases and provision of compressed driving gases.
BRIDGE pendant arms are suitable for continuous duty.
BRIDGE pendant arms can be customized with additional fittings
2.3. Instructions for Installation and Operation
Installation, testing and operation of pendant arms must be carried out in accordance with EN 60601-1, EN 737-2, and EN 737-3 and in accordance with the manufacturer’s instructions.
3. Ceiling Fixations
3.1. Static Fixing Requirements
The static certificate must be prepared prior to the installation of the ceiling fixation. Nassetti provides
a corresponding form with every ceiling fixation system supplied.
The static’s of the ceiling must be designed so that the loads of the pendant arms and the installed lighting systems or fittings, as well as any other loads present are safely carried and distributed.
The applicable regional building specifications must be observed.
Static calculations for the ceiling fixation and the load distribution in the ceiling must be provided.
The load-bearing capacity of the structure must be de signed, tested and confirmed by a structural engineer.
The interface plate or ceiling anchorage plate must lie flush with the raw ceiling.
If an existing interface plate or ceiling anchorage plate is used, care must be taken to ensure that:
The plate and the bolts are rust-free and in perfect condition.
The holes and bolts in the interface plate or ceiling anchorage plate fit the corresponding part of the upper joint of
the carrying arm.
A static certificate must also be provided for the existing interface plate or ceiling anchorage plate.

The data for the calculation of the ceiling load can be taken from the following tables: table 1, maximum
masses and bending moments and table 2, load-bearing capacities. The specified regional safety factors should also be included in calculations.

3.2. Definitions:
Figure 1 show an interface plate (3), threaded rods, nuts and washers (4) on the interface plate, ceiling suspension system for intermediate ceilings (2) and a counter plate set (1) for single and double arm type pendant arms.
3.2.1. Interface Plate
BRIDGE pendant arms are installed using an interface plate. Interface plate is the component used for the installation of pendant arms and acts as an interface between the mains supply lines and the supply connections to the pendant arms.
3.2.2. Ceiling Suspension System For Intermediate Ceiling
Nassetti offers a ceiling suspension system for intermediate ceilings for the installation of BRIDGE pendant arms, where the distance between raw and intermediate ceilings necessitates the use of some intermediate ceiling structures.
3.2.3. Counter Plate Set
Nassetti offers a complete counter-plate set, which can be used for fixing with counter–plate.

3.3. Ceiling Height Adjustments
Depending on the ceiling structure, different components are used to fix the pendant arms to the ceiling.
The absolute mounting height is limited between the minimum ceiling height and the maximum ceiling
height. When fixing pendant arms, higher or lower values cannot be used. Precise details on this are listed in Tables 3 and 4.
3.3.1. Solution 1
If the distance between the raw ceiling and the intermediate ceiling is more than 140mm and less than or equal to 240mm for the single arm type pendant arms and more than 240mm and less than or equal to 280mm for the double arm type pendant arms; the interface plate is installed onto the raw ceiling. The threaded bolts on the interface plate can span this small intermediate distance.
Fig. 2:
3.3.2. Solution 2
If the distance between the raw ceiling and the intermediate ceiling is between 241mm and 960mm for the single arm type pendant arms and between 281mm and 960mm for the double arm type pendant arms, the ceiling height is adjusted as follows:
y In the area between the raw ceiling and the intermediate ceiling, using a ceiling suspension system for
intermediate ceiling.
y In the area between the intermediate ceiling and the finished floor, using columns of variable length.

3.4. Minimum Ceiling Heights
Table 3, shows the minimum possible ceiling heights for the installation of different pendant arm types.
The distance between the upper and lower edges of the pendant arm console and the finished floor must
remain between ergonomical limits. The values in Table 3 are determined, assuming that the distance between the upper edge of the console and the finished floor is at least 1850mm. In exceptional cases, the height may be different. In these cases, the installation should be made in accordance with the special working drawing.

For intermediate ceiling structures, the distance must not be less than the minimum distance between the raw ceiling and the intermediate ceiling.
