Maintenance Principle
The Zenith ZTGSE/ZTSSE T-series
30-2500A, 200-480 Vac automatic
transfer switches, powered by TruONE™,
are designed so that the contacts last
their designed lifetime without any
routine maintenance needs. If there are
abnormal conditions such as a fault or
overload without adequate protection, or
extreme environment conditions, a failure
of ATS components may occur.
Fortunately, all critical modules, including
complete mechanism with electronics
(controller, power module, and solenoid
mechanism), HMI, and accessories are
easily replaceable. Refer to page 51 for
replacement parts.
On the other hand, when the contacts
have seen an event, or have met the end of
their lifetime, the whole switch should be
replaced – which can be done easily by
replacing the complete TruONE™ power
panel within the enclosure.
In the case you suspect a failure may be
due to manufacturer defect and covered
under warranty, see page 6.
Warning
Shock, Voltage and Arc Flash hazard
Any maintenance should be conducted by
trained and authorized personnel only.
Appropriate personal protective equipment
(PPE) shall be used when performing mainte-
nance on the service equipment.
Hazardous voltage may be present. Disconnect
all power sources before performing work
inside the Service equipment.
Failure to do so may result in serious injury
or death.
Refer to page 30 technical data for ATS
contact endurance and note that the
number of operations can be viewed in
the information menu from the HMI.
ABB recommends a routine (such as
annual) inspection to, e.g. , check
electrical termination temperatures,
ensure unit is clean, check voltage levels,
test transfers, # of operations, etc. to
ensure everything is in proper working
order.
Recommended annual inspection
includes:
Routine Inspection
- Review event log
- Check number of operations and other
switch status figures
- Visual inspection both inside and
outside of enclosure for damage
or debris
- Test transfer of load
- Observe voltage levels of both sources
within expected range
- Cable lug torque verification
