VarioTrack
dangerous voltage may remain at the terminals. To eliminate this you have to wait for at
least 120 seconds in order to allow the electronics to discharge. The task can then be carried
out safely.
No person is authorized to proceed with any change, modification or repair of the equipment without
the prior written authorisation of Studer Innotec. Use only original parts for any authorised
modification or replacement.
Do not excess the maximum rated characteristics of the equipment shown on the Type label.
The VarioTrack can be installed at altitudes up to 3000m. For installations at higher
altitudes, please contact Studer Innotec SA. The VarioTrack is in overvoltage category II,
in accordance with the norm IEC/EN 62109-1:2010 that considers all solar generators as
being in overvoltage category II.
3 MOUNTING AND INSTALLATION
3.1 S
TORAGE
The equipment must be stored in a dry environment at an ambient temperature between -20°C and
60°C. Store it in the location where it is to be used a minimum of 24 hours before commissioning in
order to avoid thermal shocks and condensation problems.
3.2 U
NPACKING
When unpacking, check that the VarioTrack has not been damaged during transportation and that
all accessories listed below are present. Any fault must be immediately reported to the product
distributor or the contact mentioned at the back of this manual.
Check carefully the packaging as well as the VarioTrack.
Standard accessories:
•
Installation and operation manual
•
Mounting plate
•
Cable-glands for battery and PV cables

OUNTING PLACE
The mounting place for the VarioTrack is particularly important and must fulfil the following criteria:
•
Protected from any unauthorized person.
•
In mobile applications, it is important to select a mounting place that ensures no vibration.
•
Protected from direct solar radiation or heat sources.
According to the environmental categories defined in the norm IEC/EN 62109-1:2010, the VarioTrack
can be mounted in a 3rd degree environment (PD3), which is in a location with dust pollution. The
VarioTrack have a high degree of protection (IP-54). However, do not expose the VarioTrack under
direct solar radiation or near a heat source. The presence of a heat source may reduce significantly
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.
The VarioTrack is electronically protected against overloads, short-circuits, overheating, polarity
reversal of the battery, polarity reversal of the PV, connexion of the panels to the battery input and
connexion of the batteries to the PV input.
