Installation

- Undo five T20 Torx screws to remove terminal

plate. The expansion card remains secured to

SP PRO.

10 - Important points

•

Failure to fill all holes in the gland plates will

compromise IP rating and the thermal design.

•

Protective cover on expansion card

must

fitted.

•

Installation of the included battery temperature

sensor is imperative for correct and accurate

battery charging. Where a managed battery is

installed the temperature sensor should remain

connected to the expansion card and remain

coiled up in the SP PRO.

•

Verify all connections are tight and have correct

polarity.

Installing SPLC models

- Wiring can only be carried out by suitably

qualified installers and must adhere to all

relevant standards.

STOP

Detailed instructions for wiring the SP PRO are contained on the following pages.

These

must

be followed before proceeding with installation.
