Keysight E4990A Impedance Analyzer 13IntroductionEnvironmental Requirementsrequirements of the safety standard. Furthermore, under that temperaturerequirement, the analyzer still conforms to the requirements of the safetystandard even when placing the analyzer with cooling clearance as follows:Protection Against Electrostatic Discharge (ESD)Set up a static- safe work- station to protect the electronic components fromthe damage by the electrostatic discharge (ESD) as shown in Figure 1-1.Figure 1-1 Example of the static-safe work stationEnsuring Adequate Free Space around Analyzer for Immediate Disconnection ofPower Cable in Case of EmergencyAs described in “Disconnection from Supply Source” on page 20, the powersupply is disconnected by removing the power cable’s connector plug fromeither the AC outlet or the E4990A unit. When installing the E4990A, ensurethat there is sufficient free space around the unit to permit quick disconnectionof the plug (from AC outlet or E4990A unit) in case of emergency.RequirementsBack ≤ 180 mmSides ≤ 60mm (both right and left)
