12 ATS POWER SUPPLY
Switch Power Type can be set as DC Power or AC Power. If DC Power is selected, then the switch can
be transferred at any time (even when both S1 and S2 are outage). If AC Power is selected, whether the
power is normal or not should be judged according to the ATS power setting and AC power voltage.
The power of ATS is supplied by controller, as long as one power is normal, this can ensure ATS voltage
power supply normally and can be transferred properly.
Users should select power supply voltage (phase voltage or line voltage) based on ATS type. If choose
phase voltage, connect the phase voltage of S1 and S2 (e.g. A phase) to normally close (Pin5) and
normally open (Pin7) contact of auxiliary output 1; connect N phase of S1 and S2 to normally close (Pin8)
and normally open (Pin10) contact of auxiliary output 2. And then connect the common output of
auxiliary output 1 and auxiliary output 2 to ATS power supplies. Enter into the parameter setting interface,
set the configurable output 1 as "ATS power L1" while set the configurable output 2 as "ATS power N". If
the ATS power supplied by Line Voltage, same procedures as above but change phase N to phase
voltage and the auxiliary output 2 should be configured according to the set. Wiring diagrams are shown
as following:
ATS phase voltage power supply ATS line voltage power supply
Note:
Normally Close (N/C) input voltage must come from S1 voltage.
Note:
ATS Close/Open relay will active only when the ATS power is normal. If ATS Power output port
is not configured, then the ATS power is supplied by L1-N phase (system default).
