perfect! you just sent to me the copy in Italian witout even my specification!!!! so you are really smart cooperative and efficient. To my opinion the best place all over to get a manual of electronics!!!!
Super nice! Good to have a manual in digital format.

3. The terminal block provided on /X0 units accepts wire ranging from 20 to 14AWG or 1.5 mm2. The terminal block provided on /X1 units accepts wire ranging from 18 to 12AWG or 2.5 mm2. When using larger wire sizes, splice to a smaller size wire at the terminal block end. The splice may need to be enclosed in a junction box if it does not pass through the fittings. 4. A screw/terminal lug is provided for securing a safety ground. To attach the safety grounding wire (green 115 volt, green/yellow 230 volt), first unscrew the terminal lug and strip and crimp the grounding wire into the lug. Attach the terminal lug to the bracket using the M4 x 10 screw provided. (LTC 9480/00 models use a M4 Nut to screw the lug to the base.) See Figure 8.
Figure 7: Feed-through Wiring 2. Screw the two 3/8-in NPT fittings into the foot of the housing. 3. Pull the cabling through the fittings and into the housing. Tighten the fitting to 4.0 N-m to 4.5 N-m (35 in-lb to 40 in-lb). This torque rating is approximately 1 to 1 1/2 turns past the point the fitting starts to grip the wire. Failure to do so will result in water damage to all electronic parts. 4. Attach the foot to the top bracket of the mount. 5. Cover the holes in the rear cap with the rubber plugs provided. Push in until flush and then release. 6.8.4 Power Connections Power connection into the housings is to be supplied through a minimum type UL Standard "SJ" cord acceptable for outdoor use. Installation must conform to acceptable NEC and local codes. For 24 volt cameras, use the chart below for selecting the proper wire size.

Note: The use of wire sizes larger than 1,5 mm2 (14 AWG) will require a splice in order to accomodate the terminal block.
1. Install one of the large 1/2-in NPT fittings into one of the holes in the rear cap. The terminal block side is preferable. If you are using the feed-through option, ignore this step. 2. Route the power cable through the fitting in the rear cap or one of the feed-through fittings in the foot.
Figure 9: Power Connections - Fan Units 5. Pull any excess wire out of the housing and tighten the fitting to 8.5 N-m to 9.0 N-m (75 in-lb to 80 in-lb). This torque rating is approximately 1 to 1 1/2 turns past the point the fitting starts to grip the wire.
