Steca Xtender
Installation and Operating Instructions 723.932 Xtender V0.511 Seite 6
DC voltage coming from the battery as well as the source of AC voltage coming from a
generator or network have been disconnected from the electrical installation.
Even when the Xtender has been disconnected from the supply sources (AC and DC), a
dangerous voltage may remain at the outputs. To eliminate this risk you must switch the
Xtender OFF using the ON/OFF button (1). After 10 seconds the electronics is
discharged and intervention may take place without any danger.
All elements connected to the Xtender must comply with the applicable laws and regulations.
Persons not holding written authorisation from Steca are not permitted to proceed with any
change, modification or repairs that may be required. Only original parts may be used for
authorised modifications or replacements.
This manual contains important safety information. Read the safety and working instructions
carefully before using the Xtender. Adhere to all the warnings given on the device as well as in
the manual, by following all the instructions with regard to operation and use.
The Xtender is only designed for interior use and must under no circumstances be subjected to
rain, snow or other humid or dusty conditions.
The maximum specifications of the device shown on the type plate, as at fig. 3b, must be
adhered to.
In the event of use in motorised vehicles, the Xtender must be protected from dust, splash water
and any other humid condition. It must also be protected from vibration by installing absorbent
parts.
2.4.2 PRECAUTIONS FOR USING THE BATTERIES
Lead-acid or gel batteries produce a highly explosive gas with normal use. No source of sparks or
fire should be present in the immediate vicinity of the batteries. The batteries must be kept in a
well-ventilated place and be installed in such a way as to avoid accidental short-circuits when
connecting.
Never try to charge frozen batteries.
When working with the batteries, a second person must be present in order to lend assistance in
the event of problems.
Sufficient fresh water and soap must be kept to hand to allow adequate and immediate washing
of the skin or eyes affected by accidental contact with the acid.
In the event of accidental contact of the eyes with acid, they must be washed carefully with cold
water for 15 minutes. Then immediately consult a doctor.
Battery acid can be neutralised with baking soda. A sufficient quantity of baking soda must be
available for this purpose.
Particular care is required when working close to the batteries with metal tools. Tools such as
screwdrivers, open-ended spanners, etc. may cause short-circuits. Consequently occurring
sparks may cause the battery to explode.
When working with the batteries, all metal jewellery such as rings, bracelet watches, earrings,
etc., must be taken off. The current output by the batteries during a short-circuit is sufficiently
powerful to melt the metal and cause severe burns.
In all cases, the instructions of the battery manufacturer must be followed carefully.
3 Assembly and installation 3.1 Handling and moving The weight of the Xtender is between 35 and 50kg depending upon the model. Use an
