The suspended mounting of the vertical ladder can be performed regard- less of the structure or type and of the distance to the wall. For this, the vertical ladders are mounted flush to solid ceiling structures. Depending on the mounting version, the maximum storey height may not exceed 3.5 m or 7.0 m.

The size and weight of the components can cause injuries. Do not mount suspended vertical ladders on your own and use roller scaffolding or a raised platform or mounting lift. Wear personal protective equipment. 6 1 Preparations for mounting Before mounting, the ladder rails must be cut according to the storey height. Note! At a storey height of 3–6 m, 2 U support connectors are required. At a storey height of 6–7 m, 4 U support connectors are required. Along the length of the ladder rails, reckon with a gap of 13 mm per pair of connect- ors. Risk of cutting During cutting work, metal chips or sharp cut edges can cause injuries to eyes and hands! – Wear protective glasses and gloves. – Deburr cut edges. 1. Cut vertical ladders to the desired length, e.g. using an angle grinder. 2. Deburr cut edges. WARNING CAUTION

During retrofitting, observe the following: – Do not exceed the maximum cable load of the vertical ladder, see also “6.6 Fastening cables” on page 31. – Observe the conditions for retrofitting the inserted insulation in the ceiling opening. – Observe the conditions for retrofitting any possibly mounted ZSE90 strain relief. 9 Checking and maintaining the system The suspended vertical ladder is maintenance-free. Carry out a visual inspection of the suspended vertical ladder as part of the inspection of the electrical systems. 10 Dismantling the system Dismantling of all the elements of the suspended rising section takes place in the reverse order to mounting. 11 Disposing of the system Comply with the local waste disposal regulations. – Product/system: As scrap metal – Packaging: As household waste Disposal after a fire Irritant effect! If there is a fire, burning cable insulation can create corrosive gases, which have an irritant and corrosive effect. When disposing of system components which have been subjected to a fire, wear breathing protection and protective clothing. If the system was subjected to fire damage, then the complete system must be removed and disposed of. We recommend obtaining the advice of the local fire damage restorer during disposal. CAUTION
