INTRODUCTION This specification covers the requirements for application of Power Series 350 (double-pole) connector assembly in high-current systems for power supplies, battery chargers, telecommunications, and material handling equipment. The connector assembly consists of a hermaphroditic housing and two closed-barrel contacts. The contacts are available in sizes 1/0, 2/0, 3/0, 4/0, and 300 and accept wire sizes (AWG) that correspond to the contact size. Reducing bushing is available for contact size 2/0 to accommodate wire size 1/0 AWG. The housing features two contact cavities each marked on top of the housing with a plus (+) to indicate positive polarity and a minus (-) to indicate negative polarity. Each contact is held in the cavity by an internal retaining spring. The hermaphroditic design of the housing ensures proper polarity in mating of the connectors. In addition, the housings are color coded to provide visual reference for proper mating and a molded-in mechanical key at the mating face prevents inadvertent mating of different colored housings (housings with same position keys will only engage housings of the same color). The housing color is also coded for voltage. The contacts feature a flared wire barrel and round-ended tab. The contacts are available in loose-piece for terminating with manual or pneumatic hand-held tools. When corresponding with personnel, use the terminology provided in this specification to facilitate your inquiries for information. Basic terms and features of this product are provided in Figure 1.

REQUIREMENTS Using the exact products and application requirements described in this document will ensure proper application; however, to ensure reliability of performance, it is highly recommended that an independent evaluation be conducted of the chosen product combinations (wire, connector assemblies, and system) before final application is approved. IMPORTANT: 3.1. Special Assembly Considerations and Safety These connectors MUST NOT be used for interrupting current; otherwise, there is risk of electrical shock. In any case, the electrical power supply must ALWAYS BE DISCONNECTED, and the connectors must ALWAYS BE DE-ENERGIZED (this might include disconnecting the wire from the battery) before mating and unmating or servicing the connectors. It is highly recommended that these connectors not be used in external power applications where the electrical potential exceeds 42 V. In applications where these connectors are located internal to a device and do not serve as the primary means of connection, high voltages are allowable. It must be determined by the original equipment manufacturer (OEM) whether the connectors meet electrical and safety requirements when used in a specific application. DANGER In applications where the connectors are used external to a device or as the primary means of disconnecting power supplies or charging equipment, care must be taken to avoid touching exposed electrical contacts as there is risk of electric shock. 3.2. Limitations This product is designed to operate in a temperature range of -20_ to 105_C [-4_ to 221_F]. 3.3. Material The housing is made of polycarbonate, rated Underwriter Laboratories, Inc. (UL) 94 V-0. The springs (inside the housing) are made of stainless steel. The cable clamp is made of aluminum. The contacts and reducing bushing are made of copper plated with silver. 2 of 9 Tyco Electronics Corporation Rev B Power Series 350 (Double-Pole) Connector Assembly 114-13119 3.4. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the housing material. B. Shelf Life The housings and contacts should remain in the shipping containers until ready for use to prevent deformation. The housings and contacts should be used on a first in, first out basis to avoid storage contamination that could adversely affect performance. C. Chemical Exposure Do not store housings or contacts near any chemical listed below as they may cause discoloration of the plated finish of the contacts or stress corrosion cracking in the housing or contact material. Alkalies Amines Ammonia Carbonates Citrates Nitrites Phosphates Citrates Sulfur Nitrites Sulfur Compounds Tartrates 3.5. Wire Selection and Preparation The contacts accept stranded (recommended a minimum of 19 strands) copper wire sizes 1/0, 2/0, 3/0, 4/0 AWG, and 300 thousands circular mils (MCM) with a maximum insulation diameter of 27.94 [1.10]. Contact size 2/0 can accept wire size 1/0 AWG with the use of the appropriate reducing bushing (as described in Paragraph 3.6). NOTE Wires with less than 19 strands may be too stiff and difficult to work with. i Tarnished copper wire must be thoroughly cleaned using a stiff wire brush, or other suitable method, that penetrates the entire bundle and cleans every conductor. The wire must be restored to a bright copper finish. The contact wire barrels are lined with silver plating to assure consistently high conductivity which will be reduced if tarnished wire is used. The wire must be cut to length. Proper strip length is necessary to properly insert the conductors into the contact. The strip length of the wire is shown in Figure 2. CAUTION Reasonable care must be taken not to nick or scrape any part of the wire during the stripping. ! Recommended Wire Strip Length 33.0-34.3 [1.3-1.35] Note: Not to Scale Figure 2 3.6. Reducing Bushing Reducing bushing is available for contact size 2/0 to accommodate wire size 1/0 AWG. When required, the reducing bushing must be installed onto the wire after stripping the wire and before inserting the wire into the contact. Placement of the reducing bushing must meet the requirements shown in Figure 3.
