V10/V7.5/V5/V3.5 Installation and Operation Manual Page 2-19Section 2 Preparation for Use and Installation Issue 3.5Table 2-5: Ac Power ConnectionAC POWER SOURCE WIRESTERMINAL 1-Phase(180–264 V ac)3-Phase(180-264 V ac)3-Phase(312-457 V ac)A1E1 Line A Line A Line AA1E2 Line B/Neutral Line B Line BA1E3 N/A Line C Line CA1E4 N/A N/A NeutralConnect the ground wire for all ac power configurations to the inside threads of theStation Reference Ground bolt (E1) at the back of the transmitter cabinet.NOTERemote control/monitor wiring terminateson the remote interface PWB (see Figure2-2). The connectors (included in theancillary kit) are solder-cup type and theterminal blocks accept wires sizes (AWG)# 14 through # 24. Cabinet entry holes forthe control/ monitor cables are provided inthe top front of the cabinet. See Figure 2-8or 2-9 for the exact cable entry location.(a) Route wires through the cable entryhole(s) to the remote interface PWB(A44). Use Figure 2-7a (V10/V7.5) or2-7b (V5/V3.5) to determine thespecific destination of each wire.(b) Pass all control/monitor wires throughthe ferrite toroid(s) installed in thetransmitter (see Figure 2-2). Ifpractical, pass the wires through eachtoroid a minimum of two turns.(c) Determine which remote controlinputs are being applied and thendetermine if they are differential orsingle-ended input. See 2.2.13(Remote Control Circuits), for moreinformation on the type of input.(d) Cut each wire to the required lengthand, if the wire connects to a terminalblock, remove 3/8 inch (9.5 mm) ofinsulation from the end of each wire; ifthe wire connects to a pin connector,remove approximately 1/8 inch (3.2mm) of insulation from the end ofeach wire.(e) Insert the control/monitor wiring intothe terminals of the remote interfacePWB or solder them to the applicableconnector pin, as identified in Figure2-7a (V10/V7.5) or 2-7b (V5/V3.5).Ensure adjacent wires do not touch(short) and the terminal block securingscrews are firmly tightened.2.3.6 Installing Ac Power SourceWiringConnect the wiring between the ac powersource and the ac distribution assembly(A1), noting it is located on the cabinetfloor (see Figures 2-2 and 2-3).(a) Switch off the ac power at the serviceentrance.(b) Remove the lower rear filter panel.Remove the cover from the acdistribution assembly (A1) to accessthese terminals. Leave the filter paneloff until installation is complete.(c) Choose the most suitable ac cableentry hole at the top or bottom of thecabinet (see Figures 2-2, 2-8, 2-9).NOTEInstall wiring in a metal conduit. Attach theconduit to the cabinet at the entry hole.When wiring is in a floor mounted trenchor the transmitter is on a pedestal, use thehole at the bottom, rear of the cabinet.(d) Get two ferrite toroids (Nautel Part #LP23, 85.7 mm) from the ancillary kit.
