Auto changeover switches standard copper wiring terminals are incoming from top and output load copper terminals from the bottom, however, frequently asked by oversea customers for reserved copper terminals, after study and test, it's available now from 100A-1600A. Please find more details below. Also, by request, two input two output copper terminals are available as well. Let us know your innovation ideas, we will do best to fulfill it !
 
101~103: Main power external indicator signal (Active AC230V/0.5A)
101- Indicator common port 102- Main power indicator signal output 103- Main power ON signal output 201~203: Backup power external indicator signal (Active AC230V/0.5A)
201- Indicator common port 202- Backup power indicator signal output 203- Backup power ON signal output 301~302: DC 24V aux. power input for generator start
301- DC24V positive input 302-DC24V negative input
401, 404: Fire linkage control signal input and feedback signal output
401, 402: Fire linkage control signal voltage-free signal input, if the signal from fire-fighting equipment is an active signal, firstly must be coverted by a smll power relay, then connect relay's NO point to 401, 402, NO contacts closing, then ATS transfer to OFF position.
403, 404: Feedback signal output when ATS transfer to OFF position, means that ATS has cutoff load power supply
Notes: when fire linkage signals actived, ATS will stop working, when emergency is over, to make ATS work again, firslty remove or disconnect fire-fighting signal, then switch once the AUTO/MANuU button, then ATS will go back to normal working mode.
501~503: Generator staarter control signals
When the backup power is generator, user can connect 501~503 terminals to the generator's controller to use generator auto starter function. 501~503 terminals internal is a set of voltage-free relay contacts, 502 is relay's common terminal, 503 is relay's NC point, 501 is relay's NO point; when main power is normal, 501 and 502 are closed, 503 and 501 are opening, if main power failure, 501 and 502 are opening, meanwhile 503 and 502 are closed, and sending generator starter signal to start the back-up generator.
