A. INSTALLATION
a.The Model R is a 2 pole, single phase DIN Rail mount STS that suits 35mm x 7.5mm rail.
b.The STS is powered from two separate sources. All precautions to guarantee
people’s
safety shall be undertaken.
c. The iSTS R is supplied with 2 DIN rail mounted fuse disconnectors (10x38 aR - 20A) placed near the unit with
sufficient space for cooling.
The iSTS and fuses can only be mounted vertically
.
d.Incoming source should be terminated to the fused switch disconnector and then to the STS active inputs. The
neutrals are not fused and should be terminated directly to the iSTS inputs. Ensure the cables are securely
connected and supported.
B. SETUP
a.Ensure that the two input sources are within tolerance, and that they are in synchronism (
±
15% of rated voltage,
<10% THD, <15º phase difference)
b.Connect your critical load to the OUTPUT.
NOTE: Due to the nature of Silicone Controlled Rectifiers (SCRs), some
load (~0.2A) is required for correct operation.
c. Connect the sources to SUPPLY 1 and SUPPLY 2. If you wish to Confirm Operation you will need to be able to
switch both sources on and off.
C. STARTUP
a.Apply power to both input sources.
b.There will be a short (15 sec) start-up period, after which the iSTS will begin powering your load.
c. Confirm that the load is receiving power.
d.Ensure that LEDs are correctly representing the supply status and load.
NOTE: Only On Supply 1 LED or On Supply
2 LED should be Red.
D. CONFIRM
a.Use the Preferred Button to highlight
‘
I
’
on the Preferred Indicator. Wait for the On Supply 1 LED to turn green (if
is not already).
b.Turn OFF Supply 1, and confirm that the iSTS transfers to
‘
II
’
(On Supply 2 LED - green).
c. Turn ON Supply 1, and confirm that the iSTS auto transfers to Supply 1 after a 3 second delay (On Supply 1 LED -
green).
d.Use the Preferred Button to highlight
‘
II
’
. Wait for the iSTS to transfer to Supply 2 (On Supply 2 LED - green).
e.Turn OFF Supply 2, and confirm that the iSTS transfers to Supply 1 (On Supply 1 LED - green).
f. Turn ON Supply 2, and confirm that the iSTS auto transfers to Supply 2 after a 3 second delay (On Supply 1 LED -
green).
