APPENDIX III: SA INVERTER OPTIONS

GENERAL

The SA41 employs a rear chassis-mounted 25-pin connector, which allows you to add a selection of optional features to your power system. Note that the software for these functions is already installed within the SA41 microcontroller.

The full range of features are:

(a) Remote Keypad:	A low profile keypad with 2-line Liquid Crystal Display, which can
	be located up to 500 metres from your SA41.
	Wiring requirements - 6 conductor shielded cable.

(b)DC Current Shunt: Consists of a 200 Amp 75mV current shunt, mounted on an insulated

base, and a twin flex loom for current sensing.

(c)Controller Outputs: Two external relay or contactor coils can be energised for various AC or DC switching applications.

(d) Alarm Inputs:	Two digital inputs that can be programmed to monitor switch contact
	status or voltage levels (refer to following circuits for examples)

SA-SB-01 INTERFACE KIT

The Interface Kit SA-SB-01 plugs into the rear of the SA41 and provides a convenient termination point for the various options outlined above. The screw terminals are numbered from 1 to 14 and the connections are as follows:

TERMINAL NO		DESCRIPTION
1	& 14	+48V with 1A internal fuse
2		Alarm input 2
3		Alarm input 1
4		0V
5	- 8	Keypad data lines
9		Keypad +12V
10 & 11		200A current shunt connections
12		Controller output 2
13		Controller output 1
