. SYSTEM OVERVIEW & OPERATION
2
.1 Description
A
Static Transfer Switch (STS) provides seamless switching between two power sources to provide
interrupted
power
to a critical load.
The
iSTS continuously monitors the supply sources for failure or degeneration and switches automatically to
the
alternate
source as required to protect the load against failure. The break in the supply transition is so short
that
it
is not seen by the critical load. This switching process is undertaken as a break before make
transfer,
preventing
overlapping which can cause large and unpredictable currents. In 4-pole models, all the
active
conductors
and the neutral are switched. In 3-pole models, only the active phases are switched. Thyristors
are
used
to undertake the switching process.
In
the case of downstream load fault conditions, the fault current drawn from the supply may degrade or
damage
the
supply sources; as a consequence should a fault current exist in the load the iSTS will inhibit a transfer to
the
alternate
source even if this causes source supply degradation or loss. This is to ensure that the fault will not
be
transferred
to the alternate supply with the possibility of degrading both sources. The current threshold
for
isolation
is pre-set to approx. 300%of the rated current.
This
unit contains fuses. The fuses are to provide for safe operation even in high fault capacity environments.
It
should
be noted that the fuses are for the protection of the semiconductor switches (SCRs/ Thyristors), not
the
load
. The iSTS does not have any automatic tripping devices, so load discrimination is undertaken in the
primary
and
secondary supply networks.

. OPERATION
3
.1 Safety
The
iSTS is powered from two separate sources. It is important that you install correct signage with
procedures
within
the enclosure and the immediate vicinity to warn personnel of this aspect and what isolation,
checking
and
precautionary processes, and procedures need to be adopted to make the iSTS and equipment
connected
to
the iSTS safe to work on.
This
equipment receives power from more than one source. Disconnect output and all input sources of
power
from
this equipment before servicing.
Do
not proceed with the installation or operation of the iSTS if it has been damaged. Carefully inspect the
iSTS
for
any damage that may have occurred during shipping, unpacking or during and after any
installation
process
.
Take
care when handling the iSTS and ensure that it is physically supported during the installation process.
At
the
end of the installation process the iSTS should be firmly and securely bolted within the rack.
Ensure
the cables are securely connected and supported and all covers plates are replaced. There should
be
NO
live exposed or accessible contacts that could cause electrical shock if contact is able to be made. This
unit
is
designed for fixed wiring installation only.
This
equipment is not recommended for installation into environments that utilise RCD earth
leakage
detectors
on the inputs of the static transfer switch. Consult Static Power for special considerations.
EARTH CONNECTION IS ESSENTIAL BEFORE WORKING ON CIRCUITS
OR CONNECTING / DISCONNECTING SUPPLIES.
TREAT AC INCOMING LEADS AS LIVE IF DISCONNECTING FROM SOURCE.

.3 Cable Termination to the iSTS
1. Attach cables using bolted lug connections to the terminals in the order show below. The terminals have
a
M6/M8 screw
2. To access the input and output terminals open the door of the enclosure and remove the terminal
cover
/GAL plate from the front of the unit. Cables enter from the bottom. Remove the gland plate and
make
holes suitable for glands.
3. Connect Active, Neutral and Earth cables to the respective terminals as marked at the terminals.
Secure
the connections on the terminal blocks, torque the screw to 25Nm /20in-lbs. All cables connecting to
the
STS should be supported by the gland and not strain the point of connection.
4. All electrical connections are to be realized by properly qualified, skilled and competent service
personnel
only.
5. Before replacing the GAL protective cover check all connections and that all ribbon cables are plugged
in
and secure. That nothing has moved out of place during handling and transport. Check all
screw
connections.
6. Before applying power replace all of the GAL panels removed prior, close the door. Check the ratings of
all
sources and cables to the iSTS, make sure that the rated voltage for the unit corresponds to the
ratings
plate and the local supply voltage.
7. Turn the maintenance bypass switch to the bypass position (either to S1 or S2). Close the incoming
source
isolators. (Note the two incoming source isolators provide power to the solid-state portion of the STS
only.
The load will be powered via the maintenance bypass switch.
8. Apply power to the STS. There will be a short 15 second start-up period, after which the iSTS LED mimic
will
show the direction of power flow.
9. Ensure that the LEDs (Green), that show which source is supplying the load is the same as the
Maintenance
Bypass Position. If not use the transfer/ priority selection to transfer to the alternate supply (same
as
maintenance bypass position).
10.Proceed to section 3.5 Start-up to connect the STS to the load from Maintenance Bypass.
When
working on live iSTS, be sure to comply with the applicable national standards and accident
prevention
rules

.4 Synchronism
The
smoothest change-over occurs when the supplies are in synchronism, so it is best to make sure the
input
supplies
are in synchronism. Some equipment (like transformers and other items) may saturate when a
transfer
occurs
when not in synchronism. This causes large currents to flow into the load which could cause damage
to
the
transformer, trip protective devices or blow fuses.
The
iSTS is configured to optimize the transfers.
3
.5 Start-up
NOTE
: Due to the nature of SCRs (silicon controlled rectifiers) some load of around 0.5A is required for
correct
operation
. Before testing the operation of this iSTS, make sure this load is applied to the output.
1. Ensure that your two input sources are within the tolerances and in synchronism.
2. If not already done, apply power to both input sources. There will be a short 15 second start-up
period,
after which the iSTS will begin powering your load.
3. Once power availability has been confirmed slowly rotate the STS maintenance bypass switch to the
N
(Normal) position
4. We recommend at this point that you connect to the STS using a laptop computer. Open up a browser
and
make connection via the LAN. We strongly encourage the setting of the date and time so that real
time
event correlation can be undertaken. The Real Time Clock is backed up by a rechargeable coin cell
battery.
If the battery is flat at the time of commissioning it may take several days to re-charge.
5. The ALARM should not be active. If it is check the following conditions that may be active:
-ON Supply 1 when priority is Supply 2
-ON Supply 2 when priority is Supply 1
- Supply 1 or Supply 2 are not in spec
- Override Switch is in position 1 or 2
- Supply 1 & 2 are not in synchronism
- The unit is too hot (thermal bi-metal switch on H.S. activated)
- There is / was an overcurrent/ overload / load fault condition

. MAINTENANCE BYPASS
5
.1 Overview
Maintenance
Bypass mode allows the load to be connected to one supply without going through the
power
circuit
of the STS.
The
maintenance bypass switch is located on the front of the power module. The switch is normally in the
“N”
position
and can be used to bypass the internals of the STS to either “Supply Source 1”or “Supply Source 2”.
THE MAINTENANCE BYPASS SWITCH SHOULD ONLY BE USED TO SELECT THE PRESENTLY OPERATING SOURCE.
IT CANNOT BE USED TO TRANSFER THE CRITICAL LOAD FROM ONE SOURCE TO THE OTHER.
The maintenance bypass switch utilises make-before-breakswitching, incorrect operation of the
maintenance bypass features could result in dangerous voltages occurring and short circuits.
Note
: A padlock can be used to stop inadvertent or unauthorized operation of the switch.
5
.2 Maintenance Bypass Procedure
Bypass
Mode on Supply 1
1. Use the TRANSFER pushbutton on the front of the unit to transfer the load to Supply 1.
2. TURN OFF Supply 2 using the isolator switch on the front of the unit.
3. Finally operate the Maintenance Bypass Switch by turning to position 1. The unit will now be in
bypass
mode on Supply 1.
Bypass
Mode on Supply 2
1. Use the TRANSFER pushbutton on the front of the unit to transfer the load to Supply 2.
2. TURN OFF Supply 1 using the isolator switch on the front of the unit.
3. Finally operate the Maintenance Bypass by turning to position 2. The unit will now be in bypass mode
on
Supply 2.
Testing
the iSTS
Once
the unit is in maintenance bypass mode on either Supply 1 or 2, the unit can be tested as the output of
the
solid
-state switch is disconnected by the maintenance bypass switch. To service the switch and before
removing
the
internal Gal panel turn-off the isolators on the terminal enclosure and remove the control fuses. This will
not
affect
power flow to the load when in maintenance bypass.

.3 Reinstatement from Maintenance Bypass
1. Turn on both Supply 1 and Supply 2 circuit breakers located at the front lower terminal section of the
unit.
Wait for the unit to start up. The mimic on the display screen should show Supply 1 and 2 as GREEN
to
indicate that both supplies are active in the STS.
2. Move or operate the Preferred Source selection switch to the supply that is in bypass.
3. Check the mimic LEDs and ensure that the STS and the maintenance bypass are the same (e.g.
if
Maintenance Bypass is at position 1 then the STS portion powering the load should have 1 Green)
4. Finally operate the bypass switch, returning it to the middle position.
5. The unit will now be normal operation mode.

.2 Load Fault
In
case of sustained high current output load faults, the iSTS will inhibit a transfer to the alternate supply even
if
this
means degradation or loss of source supply. It is therefore imperative that you ensure that the
discrimination
with
downstream and upstream protective devices ensures that the downstream protective device always
clears
the
fault first.
In
case that all output is lost the faulty equipment should be located and removed from the iSTS output
before
re
-instatement of power.
If
the unit is inoperable then it should be returned to the manufacturer for repair or replacement.

8
. RECOMMENDED MAINTENANCE SCHEDULE
If
the unit is faulty then it should be removed from service as per the accompanying procedure and a
qualified
experienced
service agent should affect repair.
▪Once per month record the operating variables and compare with the specifications and
operating
parameters to ensure that the unit is operating correctly.
▪Check the Event History and correlate any recorded events since last observation with real
occurrences.
Report / investigate any suspicious entries.
▪Inspect cable connections for overheating.
Contact
Static Power for help with troubleshooting and parts replacement.
