5.7Camera/Lens Wiring

WARNING: Only use the cables specified under INSTALLATION, Cable Requirements for wiring of all cameras and lenses.

5.7.1Liquid-Tight Fittings

The dual-male threaded portion of the two 1/2in. NPT and one 3/8in. NPT liquid-tight fittings are preinstalled in the rear of the base assembly. If possible, do not remove or loosen these parts. They have been installed to a specified torque to prevent water damage. The small 3/8in. NPT fitting will accept cables with diameters from 4.6mm (0.181in.) to 7.9mm (0.31in.). The two large 1/2in. NPT fittings will accept cables with diameters from 4.3mm (0.170in.) to 11.9mm (0.470in.). See FIGURE 6.

Be sure to securely tighten all fittings to ensure a liquid-tight seal. Not doing so could damage the camera, the housing, or both.

If a sealant will be used, be sure it is a neutral cure type. Sealants that release acetic acid may harm camera electronics.

If it is necessary to use PG type conduit, a TC9385PG kit is available. The TC9385PG kit contains a wire grip with two PG11 and one PG7 tapped holes. The NPT wire grip is removed and replaced with the PG version.

5.8Plug Insertion

If no lens control or feed-through wiring will be used, install the 3/8in. NPT plug provided. Remove the liquid-tight fitting and insert the plug in the small bottom center 3/8in. NPT hole. Use a 8mm or a 5/16in. hex wrench to tighten securely. Failure to do so will result in water damage to all electronic parts. See FIGURE 7.

5.8.1 Supply Power Connections

The LTC 9385 Series housings offer the user one of three voltage configurations. The suffix to the housing model number will determine the supply voltage required.

Any camera installed in the LTC 9385 Series housings must be of the same voltage type as the housing. The integral heater/defogger also requires the same voltage as the housing. These housings do not contain step down or isolation transformers. See the Model Designation chart for suffixes and supply voltages required.
