Such duties include opening or closing breakers, closed door racking of breakers, reading of instruments, or other such activities that do not require the opening of doors or removal of covers except doors or covers of compartments specifically identified aslow-voltage control or instrumentation compartments. It is designed and performance tested to ANSI C37.20.7 to provide an additional degree of protection from internal arcing faults. Should additional information be desired, including replacement instruction books, contact yourSiemens representative.ScopeThese instructions cover the installation and maintenanceof Siemens Type 2B WL Arc Resistant metal enclosed low voltage switchgear assemblies, using the Type WL UL -1066 low voltage power circuit breakers. A typical indoor Type 2B WL arc resistant switchgear assembly is shown in Figure 1.This instruction manual acts as a supplement to Siemens Rear and Front Connected Type WL Low Voltage Switchgear Instruction and Installation Guides. This manual discusses the special features and maintenance associated with arc resistant switchgear.General DescriptionType 2B Arc Resistant WL switchgear is an assembly of an indoor enclosure and mounting base with arc plenum. It has an insulated bus bar system, removable rear cover panels/ doors secured with captive screws, section barriers and cable compartment barriers. (Sections Barriers & Cable compartment barriers are Optional for FC). Flame retardant barriers and shutters are provided in power circuit breaker compartments. One piece circuit breaker compartment doors with insert panels for fuses, indicating lights and control switches are used when required.The following must be maintained for proper functioning of Arc Resistant switchgear. 39” (990) minimum front aisle (FS3 4 Pole breaker require 42” [1066] minimum), and 36” (914) minimum rear aisle (Rear Connected only).

A continuously energized transformer needs periodic cleaning and maintenance to remove accumulations of dust or dirt from cooling ducts and other surfaces. Large accumulations may reduce cooling efficiency and lead to overheating. Cleaning and maintenance are recommended at least once a year in relatively clean installations and at more frequent intervals in more heavily contaminated atmospheres.Transformers that are de-energized for long periods of time generally require more frequent maintenance and cleaning to ensure removal of contamination. CleaningAccumulation of dirt on insulating surfaces becomes a hazard when a considerable amount of moisture is absorbed. Vacuuming is the recommended method for cleaning. Special attention should be given to cooling ducts within the winding. Low-pressure dry air can be used if care is taken to avoid driving the contamination into the insulation.—TR ANSFORMERSLow Voltage Dry Type TransformersCleaning and maintenance tips to keep your transformers in optimal conditionUnder normal environments and operating conditions, dry type transformers are virtuallymaintenance free. However, they do require occasional internal cleaning, care and inspection. The frequency of inspection, cleaning and care will depend on the atmospheric and/or environmental conditions at where the transformer is installed.Moisture is detrimental to most insulation systems. It is advisable to dry out any transformer that has been exposed for long periods of time to high humidity.Whenever moisture is visible on insulation surfaces, the unit must be dried before being energized. If moisture is evident, the unit should be dried out by placing it in an oven, by blowing heated air over it, or by placing strip heaters under the coil windings. The temperature of the heated air should not exceed 110C/230F. If strip heaters are used, the elements should not be allowed to come in contact with the transformer. Heat should be applied to both the front and rear of thetransformer. Transformers may be subjected toflooding, direct rain or similar applications of water. In such cases, normal drying techniques may not be adequate and the factory should be consulted as the transformer will most likely need to be replaced.MaintenanceMaintenance would include dust removal and/or drying (if applicable), tap changing, tightening of bolted connections, general servicing and inspection of auxiliary devices. Additional information related to the installation and maintenance of general purpose transformers can be found in ANSI publication C57.94, “Guide for Installation and Maintenance of Dry Type Transformers”.Contact your local ABB representative for more information.—We reserve the right to make technical changes or modify the contents of thisdocument without prior notice.
