charger if the user does not (carefully) follow
the procedures.
2.2 USE FOR INTENDED PURPOSE
1 The Mass Combi is constructed as per the applicable
safety-technical guidelines.
2 Use the Mass Combi only:
xfor the charging of lead acid batteries and the
supply of users attached to these batteries, in
permanent systems;
xfor the conversion of a DC voltage from a battery
to an AC voltage.
xconnected to a dedicated double pole circuit
breaker and earth leakage switch.
xwith a fuse, protecting the wiring between Mass
Combi and battery;
xin a technical correct condition;
xin a closed, well-ventilated room, protected
against rain, moist, dust and condensation;
xobserving the instructions in the users manual.
WARNING
Never use the Mass Combi in situations
where there is danger of gas or dust explosion
or potentially flammable products!
3 Use of the Mass Combi other than mentioned in point
2 is not considered to be consistent with the intended
purpose. Mastervolt is not liable for any damage
resulting from the above.
2.3 ORGANIZATIONAL MEASURES
The user must always:
xhave access to the user's manual;
xbe familiar with the contents of this manual. This
applies in particular to chapter 2, Safety
Guidelines and Measures.
2.4 MAINTENANCE & REPAIR
1 If the Mass Combi is switched off during maintenance
and/or repair activities, it should be secured against
unexpected and unintentional switching on:
xremove the AC supply
xremove the connection to the batteries
xbe sure that third parties cannot reverse the
measures taken.
2 If maintenance and repairs are required, use only
original spare parts.
2.5 GENERAL SAFETY AND INSTALLATION
PRECAUTIONS
xDo not expose the Mass Combi to rain, snow, spray,
moisture, excessive pollution and condensing
circumstances. To reduce risk of fire hazard, do not
cover or obstruct the ventilation openings. Do not
install the Mass Combi in a non-ventilated area,
overheating may result.
xThe Mass Combi must be provided with an equipment-
grounding conductor to the AC-input ground terminal.
Grounding and all other wiring must comply with local
codes and ordinances.
xIn case of fire, you must use the fire extinguisher which
is appropriate for electrical equipment.
xShort circuiting or reversing polarity will lead to serious
damage to batteries, Mass Combi and the wiring.
Fuses between the batteries and the Mass Combi can
not prevent damage caused by reversed polarity and
the warranty will be void.
xProtect the DC wiring with a fuse, according to the
guidelines in this manual.
xConnection and protection must be done in
accordance with local standards.
xDo not work on the Mass Combi or system if it is still
connected to a power source. Only allow changes in
your electrical system to be carried out by qualified
electricians.
xCheck the wiring and connections at least once a year.
Defects such as loose connections, burned cables etc.
must be corrected immediately.
