1. Plug the RV power cord into an approved RV receptacle.
2. Verify the delay indicator is ashing, and the line lights are green.
3. Once caution light stops ashing (this takes 128 seconds), verify RV
power is on.
NOTE: USING WITH TRC VOLTAGE REGULATOR
If using Surge Guard with TRC Voltage Regulator (10175 or 10176) the
voltage regulator should be positioned between the power pedestal (shore
power) and the Surge Guard.
WARNING: It is extremely important that the terminal covers
(Model 35530 only) are in place prior to applying power to the RV.
Failure to comply with these instrctions may result in a shock hazard.
