Precautions to ESD
Please note that the Micronix PV modules must be handled with respect to ESD (Electrostatic
Discharge). Electrostatic Discharge to the PV modules must be avoided.
Before removing the module from the protection bag, the user must be discharged using a grounded
wrist ribbon.
Settings and connections
ST1
To set the fast charge current to 1A, install a jumper at ST1 (factory default). To set the fast charge
current to 0.5A, remove jumper at ST1.
J1
Connect an external temperature sensor at J1 (i.e. PV-5127-TW40) if the battery temperature is to
be supervised during the charging process. The battery temperature control can be disabled by
installing a jumper at J1 (factory default). Leave ST1 unconnected when PV-5127 is used with a
PV-1075 battery module. See section
Connectors
and
Battery monitor and charger.
ST3
Connect a jumper in position ‘On-board sensor’ if the system temperature is to be measured by the
on-board sensor. If the system temperature is to be measured by an external sensor, leave ST3
unconnected. To disable the system temperature control, install a jumper in the position ‘10°C’
(factory default).
J2
Connect an external temperature sensor at J2 (i.e. PV-5127-TW40) if the system temperature is to
be supervised by an external sensor. Otherwise leave J2 unconnected. See section
Connectors
and
System temperature.
CN2
If external LED indicators or the heater and fan control outputs are used, connect these through
CN2. Otherwise leave CN2 unconnected. See section
Connectors
.
CN3
If the ‘simple signalling’ protocol is to be used for the UPS control, connect a suitable cable (i.e.
CDB-9F) between CN3 and a COM port on the CPU. Otherwise leave CN3 unconnected. See
section
UPS Control
.
CN10
If your CPU has a 5V Standby power input and a PS_ON output, connect them to the corresponding
pins in CN10 (ATX). Otherwise place a jumper on the two leftmost pins in CN10 to permanently
activate PS_ON (factory default). See section
Connectors
and section
UPS Control.
