H2B USER'S MANUAL - 550145G
2.7 GENERAL NOTES AND PRECAUTIONS
- Never combine SCR low frequency choppers with H2B modules, as the filter condens-
ers contained in the H2B module alter SCR chopper functioning, subjecting it to exces-
sive workloads.
Thus, if you wish to use two or more control units (e.g. lift + traction), they must all be of
the high frequency ZAPIMOS family.
- Do not connect the chopper to a battery with a different nominal voltage than that indi-
cated on the chopper identification plate. A higher battery voltage can cause MOS
failure. A lower battery voltage prevents the module from functioning.
- During battery recharge, the H2B module must be completely disconnected from the
battery, as, in addition to altering the charge read by the battery charger, the module can
be damaged by the overload voltages generated by the charger.
- The H2B module must only be supplied using a traction use battery; do not use outputs
of converters or power suppliers. For special applications, please consult the nearest
ZAPI service centre.
- Start the machine the first time with the wheels raised, to ensure that connection errors
do not create safety risks.
- With the key off, the filter condensers inside the module may remain charged for several
minutes.
For safe operation, we recommend that you disconnect the battery and short circuit the
power positive and negative on the chopper for a few seconds with a resistance of
between 10 ohm and 100 ohm.
- The susceptibility and the electromagnetic emission are remarkably influenced by the
installation conditions. Take particular care of the length, of the electrical connections
and of the braided wires.
Therefore ZAPI declines any responsibility for badrunnings that can be attributed to the
above mentioned circumstances, above all if the manufacturer of the machine doesn't
carry out the tests required by the regulations in force (conducted emissions, irradiated
emissions, IEC 801 - 2 (ESD), IEC 801 - 3 (irradiated susceptibility), IEC 801 - 4
(burst), IEC 801 - 5 (surge), IEC - 6 (conducted immunity)).
