3. ESD Procedure
3.1. Electrostatic Discharge
Static electricity is a stationary form of electrical charge. This charge is due to the transfer of electrons within a body or from one body to another. The magnitude of the charge depends on the size, shape, composition and electrical properties of the substance that make the bodies.
Once a body develops a static charge, it will look for a conductive surface to discharge. This is called Electrostatic Discharge (ESD). This discharge is only felt when the charge is larger than 3500 volts, yet many components are sensitive well below this level.
Potentially dangerous levels of ESD can generate from the following common manufacturing sources:
• Plastic (bags, containers, binders)
• Paper (procedures, DHRs, pick slips)
• CRT Monitors
• Clothing
Subassemblies and equipment that contain ESD sensitive devices (without adequate circuitry) are also ESD sensitive.
Avoid sliding ESD sensitive components across other materials. Sliding materials together can create the build up of an electrostatic charge.
3.2. Electrostatic Dissipative Wrist-Straps
Wrist-straps should be worn during the handling of ESD sensitive devices. The wrist-strap should contain an internal 1Mohm resistor to protect the operator in the case of accidental high voltage being applied to the workstation surface.

7.19 Suspension Mounted EndoLite
7.19.1 General Information
The ENDO light is an accessory option that mounts to the Chromophare suspension. It is mounted to the central bearing shaft assembly attached to the bottom of a horizontal arm. It provides background light when the full light of a surgical light is not needed.
There are two (2) variants of the suspension mounted Chromophare ENDO light. The rst is for suspensions with a surgical light mounted on the bottom arm of the suspension. With this unit, the power and CAN bus are received from the output of the contact block mounted on the bottom arm of the suspension thru a transition cover (Figure 1).
The second variant is used when there is a non-powered bottom arm (single/dual at panel) on the suspension. With this unit, the power and CAN bus are received from a wireset brought down from the top of the suspension thru the center of the shaft (Figure 2). Both units are functionally the same and are energized from the controller using the ENDO selection.
