Installation Procedure - Western SPC07-IP2 Manual Del Usuario

Installation procedure:

Avoid direct exposure to sunrays (caution: over-heating), avoid water and humid environments.
PAY ATTENTION TO POLARITIES AND AVOID SHORT-CIRCUITS; they are destructive and cancel warranty.
Connect the battery cables only after having connected all the others; do not insert a further blocking diode:
you would annul the "light sensor" detection. Put the battery in the chosen place, connecting in the proper
way the cables and reducing the distance from the charge controller more that you can.
We advise the external NTC temperature sensor (optional) in case of big differences in temperature between
controller and batteries. Connect to the proper connector the external NTC temperature sensor and, if
requested by the chosen configuration, connect also either the infrared sensor (PX01) or the switch for
remote habilitation. On starting the LED must effect a green and red lightning to indicate a correct power on.
To test if the installation of the controller has been made in the right way it is necessary to verify that at
sunset the load switches on according to the configuration that has been set by the Switches (ser the
following page). To simulate SUNSET we advise to cover carefully the PV module using a quite thick
cardboard; it could be necessary to cover even the rear side of the PV module. We saw that if you connect to
the controller SPC07-IP2 some kind of PV modules the controller is not able to detect the night. If you are in
such conditions, please contact
Configurations:
In all configurations the following processes are guaranteed:
The regulation of the battery's charge voltage, compensated in temperature, by external or internal NTC.
Load deactivation at reaching Low-Battery threshold (a red ligthning), selectable to 11V (dip switch 6 ON) or 12 V
(dip switch 6 OFF).
System inhibition at reaching Overtemperature threshold (two red ligthnings of the LED).
It is possible to exit from a low battery condition only during daylight.
