• Conductors test free of all grounds before you connect the city card to the system.
• Wiring for reverse polarity is between 20 AWG minimum and 12 AWG maximum.
• Wiring for local energy is between 18 AWG minimum and 12 AWG maximum.
• Leave the 2.2 k, 1/2 W resistor on an unused terminal.
Note:
1. The city card is intended for connection to a polarity reversal circuit of a remote station receiving unit that has compatible ratings:
19 VDC to 32 VDC, 2 V peak to peak ripple maximum.
