Housing

The BLE100 is furnished in a BLE-HSG/15 aluminum housing that protects the electronics from weather and dissipates internally generated heat.

Figure 2-3 illustrates the BLE-HSG/15 housing and provides its dimensions.

Coaxial cable connections to the housing are made using conventional 5/8 inch ⋅ 24 threads per-inch stinger-type connectors. Four port plugs in the cover enable access to internal test points without opening the housing.

The BLE-HSG/15 differs from the housing of the 10A BLE (model BLE-75SH and BLE-75JH) and the JLX series of line extenders. However, you can upgrade the 10A BLE and the JLX series of line extenders to the 15A BLE100 using the existing housing. To upgrade from 10A to 15A, use the BLE-15A platform assembly kit (P/N 951941-006-00). The BLE-15A kit contains 15A platform assemblies. As an alternative to the kit, you can order the BLE100 electronics module configured as a 10A unit (see Fig.2-2 BLE100 ordering matrix, Housing).

Two messenger clamps are located on the side of the housing (Figure 2-5) and are secured with 5/16 inch ⋅ 24 threads-per-inch stainless steel bolts. The bottom of the housing also contains two 5/16 ⋅ 24 threaded holes located on the vertical center-line separated by four inches center-to-center. Use these holes and the bolts from the messenger clamps for pedestal and surface-mounting installations.
