manual abstract
.. The device must be in a restricted access area (dedicated equipment rooms, equipment closets, or the like) where the applicable requirements of the device are met. .. The equipment must be in a controlled environment (an area where the humidity is maintained at levels that cannot cause condensation on the equipment, the contaminating dust is controlled, and the steady-state ambient temperature is within the range specified). .. Do not install this equipment at a combustible place. .. This equipment has been evaluated for use in a continuous ambient temperature of up to 50°C. .. Torque electrical connections conform to the values specified on labels or in the product documentation. .. Refer to the product documentation for the proper hardware. Use only the parts specified in the equipment documentation .. Improper fuses/circuit breakers may cause body injury or equipment damages. .. External circuit breakers must be sized as required by the applicable local codes. Refer to the equipment ratings to Safety assure rating of equipment no to exceed 80% of the value of the breaker chosen. 3.2 Warning Statements and Safety Symbols The symbols may sometimes be accompanied by some types of statement, for example “Hazardous voltage/energy inside”, “Risk of injury”. “This device must be accessed only by qualified personnel.” This symbol identifies the need to refer to the equipment instructions for important information. This symbol is used to identify the protective safety earth ground for the equipment. This symbol is used to identify other bonding points within the equipment. This symbol is used to identify the presence of hazardous ac or dc voltages.It may also be used to warn of hazardous energy levels .. Note: These symbols are used to identify the presence of hazardous AC/DC main voltage and also can be used to alarm the level of danger. Safety 3.3 Precautions When working on this type of equipment, the following precautions must be noted: .. This unit must be installed, serviced, and operated only by skilled and qualified personnel who have the necessary knowledge and practical experience with electrical equipment and who understand the hazards that can arise when working on this equipment. .. The PSE2500-A3 system can be powered by multiple AC inputs. Ensure that the appropriate circuit protection device for each AC input being serviced is disconnected before servicing the equipment. .. High leakage currents may be possible on this type of equipment. Make sure the equipment is properly earth grounded before connecting power. .. Hazardous energy and voltages are present in the device and on the interface cables that can shock or cause serious injury. Follow all safety warnings and practices when servicing this equipment. .. Exercise care when servicing this area. In addition to proper job training and safety procedures, the following are some basic precautions that should always be used: .. Use only properly insulated tools. .. Remove all metallic objects (key chains, glasses, rings, watches, or jewelry, and so on). .. Wear safety glasses. .. Test circuits before touching. Safety .. Lock out and tag any circuit breakers/fuses when possible to prevent accidental turn on. .. Be aware of potential hazards before servicing equipment. .. Identify exposed hazardous electrical potentials on connectors or, wirings. (Note the condition of these circuits, especially any wiring). .. Be careful when removing or replacing any covers – avoid contacting any circuits. Installation and DebuggingChapter 4 Installation and Debugging 4.1 Introduction This section outlines the sequence for installing the PSE2500-A3 device, including plug-in modules, as well as test procedures for verifying the integrity of the installation. 4.1.1 Guidelines The device may be installed to allow rear and front access. All cables may be routed through conduit openings, and all the operation can be completed on the front side. 4.1.2 EMI Considerations When running the dc output cables, pair the positive and negative conductors over as much of their length as possible to minimize loop areas. 4.1.3 Installation Tools and Hardware You will need the following tools and hardware to install and test the PSE2500-A3 unit: .. Wire cutters and strippers .. Heat shrink gun and appropriately sized heat-shrink tubing .. Electric screwdriver with 6 mm (0.24 in.) hex head with variable torque range, 0 to 120 in lbs (0 to 13.6 N.m) .. Adjustable wrench .. M8 sleeve Installation and Debugging .. Digital meter with an accuracy of ± 0.02% .. Small flat screw driver .. ESD wrist strap 4.1.4 Safety Warning: .. Only qualified personnel can install and service the PSE2500-A3 device. .. Hazardous energy is present in the device and on the interface cables, and ill shock or cause serious injury or death if safety precautions are ignored. Follow all safety warnings and practices when servicing this equipment. 4.1.5 Installation Sequence Review all safety warnings in Section ...
