• Stuffed lead acid batteries contain high explosive gas (hydrogen / air mixture). Never smoke and or provovate sparks near the
batteries. Avoid electrostatic discharges - wear cotton clothing and, if necessary or required by local law, ground yourself
before maintenance work.
• Always wear the appropriate clothing and take care they are suited to statutory safety and protective arrangements.
Avoid areas that are not suited for battery installations
Standard modules shall not be used in case of ...
• outdoor or open space usage as well as non-water protected, enclosed spaces.
• dusty rooms or places with high levels of dust.
• in areas of high concentration of saline as well as oxidizing gases.
• the place is next to open fire, spark zones, heat sources or inside heat extreme zones.
• areas that are known for high temperature fluctuations that cannot be normalized by environmental control systems.
• areas that are known for with high vibration or mechanical movements
• areas that are known for gas concentration or other flammable substances
Note
In some cases. there is a small and fluently defined borderline that decides about a location is appropriate or inappropriate for installing
and operating a BACS system. If in doubt, please contact the GENEREX Support Team, we are happy to advise you about the
possibilities as well as environmental conditions to be met.
Just write a small mail to our support team: BACS@generex.de.
if you need to install BACS and the area is known to deviate from a standard installation for technical or environmental reasons:
GENEREX offers especially insulated and sealed modules to handle these installation scenarios.
To be noted during installing a BACS
1. High voltage danger
Do not open the BACS sensor; Do not attach objects to the battery or to the BACS modules! The BACS modules and cables could be
under high voltage!
2. Magnetic fields
Keep in mind that every live wire creates a magnetic field around it. The strength of the magnetic field dependents on the current: a
large If insufficient shielded, a UPS system can generate very high electromagnetic interference (EMI). Therefore, avoid the installation
or operation of technical equipment that is susceptible to electromagnetic fields.
Take care for technical staff using a cardiac pacemaker - Magnetic interferences may harm regular functions and even destroy these
vital devices!
3. Trained and BACS qualified technical staff only!
BACS is installed on batteries that can be under high voltage during installation. As soon as the BACS measuring and connecting
cables are connected to the batteries, they may be under high voltage, too. To prevent short circuits, ensure the system is disconnected
before performing any maintenance or installation work in companion with BACS cables. Since a certain order must be adhered to,
special trained and certified BACS technicians are required..
Note
Need a BACS training for your technical staff? Speak to us – our BACS training team will be pleased to advise you the best way to get
a BACS certification training.
4. Replace damaged batteries before installing BACS for the first time
Damaged are batteries often not determinable by a mere visual inspection. A damage can be found during a measuring the internal
resistance - the higher the internal resistance, the worse the current condition of the battery.
The problem:
If a battery is highly damaged that the internal resistance exceeds maximum possible highness, the charge / discharge current will no
longer be able to pass through the battery. Becaus the charge/discharge current must find a way it would seek the path of least
resistance:The BACS module. As a consequence, unplanned heat will be generated that can damage or destroy the BACS module over
time. Due to this fact, do not continue and use batteries in a battery bank that are already detected externally as defective or if the
BACS module measures a very high internal resistance!!
