2. SAFETY INSTRUCTIONS
● It is advised to read this manual carefully before the product is installed and put into use.
● This product is designed and tested in accordance with international standards. The
equipment should be used for the designated application only.
● Install the product in a heatproof environment. Ensure therefore that there are no
chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the
equipment.
● Ensure that the equipment is used under the correct operating conditions. Never operate
it in a wet or dusty environment.
● Never use the product at sites where gas or dust explosions could occur.
● Ensure that there is always sufficient free space around the product for ventilation.
● Refer to the specifications provided by the manufacturer of the battery to ensure that the
battery is suitable for use with this product. The battery manufacturer's safety instructions
should always be observed.
● Protect the solar modules from incident light during installation, e.g. cover them.
● Never touch uninsulated cable ends.
● Use insulated tools only.
● At a voltage >75 V, particularly with regard to the open circuit voltage of the PV array, the
solar system must be installed according to protection class II. A chassis grounding point is
located on the outside of the product. If it can be assumed that the grounding protection is
damaged, the product should be taken out of operation and prevented from accidentally
being put into operation again; contact qualified maintenance personnel.
● Ensure that the connection cables are provided with fuses or circuit breakers. Never
replace a protective device by a component of a different type. Refer to the manual for the
correct part.
● Connections must always be made in the sequence described in section 4
● The installer of the product must provide a means for cable strain relief to prevent the
transmission of stress to the connections.
● In addition to this manual, the system operation or service manual must include a battery
maintance manual applicable to the type of batteries used.
● Use flexible multistranded copper cable for the battery and PV connections.
The maximum diameter of the individual strands is 0,4 mm/0,125 mm² (0.016 inch/AWG26).
A 25 mm² cable, for example, should have at least 196 strands (class 5 or higher stranding
according to VDE 0295, IEC 60228 and BS6360).
An AWG2 gauge cable should have at least 259/26 stranding (259 strands of AWG26).
Maximum operating temperature: ≥ 90°C.
Example of suitable cable: class 5 “Tri-rated” cable (it has three approvals: American (UL),
Canadian (CSA) and British (BS))
In case of thicker strands the contact area will be too small and the resulting high contact
resistance will cause severe overheating, eventually resulting in fire.
Danger of explosion from sparking
Danger of electric shock
