6. How it works Recommendation Roof pitch To facilitate effective functioning of the DE ICING BOX we recommend a roof pitch of 25 degrees or more Roof area Prerequisite for use of the DE ICING BOX is that the area below the solar modules is free of obstructions so that the snow can slide off unhindered Safety Owing to the fact that the DE ICING BOX when in use leads to snow sliding off the PV modules and the roof safety is a top priority in the area below the edge of the roof We recommend you fence off the danger area in Some manner Always switch the DE ICING BOX off when it is not required Owing to the way it operates a DE ICING BOX that is switched on consumes up to 50 W of power depending on your PV generator if the inverter has not yet been switched to de icing mode Its typical power consumption is less than 10 W and under 0 5 W when switched off The de icing function can only properly fulfil its purpose if its use is carefully thought through and planned For this reason keep a log especially during the first winter period of when and how you use it and the results achieved see chapter 7 3 1 Safety information relating to the DE ICING BOX Please read the following safety information and instructions before you put the system into operation for the first time in order to avoid personal injuries and or property damage These instructions must be complied with at all times Do to attempt to install or put this devi
