in accordance with UL 96 and 96A. The outdoor unit drop cable shall be run
separately from the earth cable and any cables carrying hazardous voltages.

damage components in the SIU. The addition of a master socket fitted with discharge tubes
should protect internal wiring and customers premise equipment from damage.
