OUNTING PLACE
The mounting place for the VarioString is particularly important and must fulfil the following criteria:
Indoors
Protected from water and dust in a location without condensation.
Protected from any unauthorized person.
In a place where the relative humidity does not exceed 95%
In a place where the ambient temperature is between -20 and 55°C
In mobile applications, it is important to select a mounting place that ensures no vibration.
Protected from direct solar radiation or heat sources.
It should not be mounted directly above the battery or in a cabinet with the battery
The ventilation vents should be clear at all times and at least 20 cm from all obstacles that
could alter the ventilation of the device.
Given the norm IEC/EN 62109-1, the degree of pollution in the installation area should be at
maximum PD2 for the VS-120 and PD3 for the VS-70.
The support for the VarioString and the environment in which it is contained should not be
flammable.
The presence of a heat source may significantly reduce its rated power. Similarly, insufficient
ventilation may lead to the overheating of some internal components of the equipment. In this case,
the device will automatically limit its power as long as this abnormal situation persists.
As far as possible, reduce exposure to sudden temperature variation: important heat variation may
create undesired and harmful condensation inside the equipment.

IMENSIONS
The VarioString is a heavy equipment (5.5 kg (VS-70) and 7.5 kg (VS-120)) and must be mounted
to a support (wall) designed to bear such a load. It is imperative to ensure a complete and safe
fastening of the equipment. If simply hung, it may fall down and cause severe damages.
The VarioString must be installed vertically. A distance of at least 5cm between the units and/or 20cm
around the equipment is required to guarantee adequate ventilation.
If the VarioString is installed in a closed cabinet, it must have sufficient ventilation to guarantee that
the ambient temperature is kept within the operating limits of the VarioString.
In motor vehicles, or when the support undergoes significant vibrations, the VarioString is to be
mounted on anti-vibration elements.
