connecting to shore power is ok. however, if your chassis batt is charged already, the batt will not be under charge.. the HWH-FWS requires somewhere around 1.5V to operate. If chassis batt is at 13, when operating the hwh fws, the chassis batt will drop under 12v. Thas when you MAY create problem with the hwh fws open/close. (low Voltage may not move the slide fast enough or far enough, in some cases) You can wait till the charge kicks in. newmar techs used to tell us (older units) to turn head lights on till the chassis charge kicks in. Running the engine is much better, as the chassis batt will be under charge all along.
