3.4 Lightning Protection
Metal Oxide Varistors and Transient Voltage Suppressors on the panel help protect against voltage surges on
input and output circuits of the PFC-7500 Series panels. Additional surge protection is available by installing the
Lightning Suppressors.
3.5 Keypads
You can connect the Models RA-7630 or RA-7692 keypads to the 4-wire keypad bus provided by the panel on terminals
7, 8, 9, and 10. Do not use shielded wire for the keypad bus.
