The benefits of the SE configuration are:
• Combined service disconnect and over-current protection in the
• Fewer components and power connections reduce maintenance
1.2.3 Optional Load Shed
Four sets of contacts are available and can be used to control
large connected loads on the generator (i.e. air conditioners, hot
tubs, etc.)
1.3 Transfer Switch Catalog Number Identification
ATS equipment catalog numbers provide a significant amount of
relevant information pertaining to a specific piece of equipment.
The Catalog Number Identification Table (see Table 1) provides
the required interpretation information.
Table 1. ATS Catalog Numbering System
1.4 Environmental and Operational Conditions
Normally, an ATS is applied indoors in an electrical equipment
room. It can also be used for normal outdoor applications (with
standard NEMA 3R enclosure) where the equipment is subject to
falling rain, freezing temperatures, and 95% humidity (non-con-
densing). The ambient temperature range for operation is
between -20 and 70°C (-4 and 158°F).
1.5 Glossary
With respect to their use within this document and as they relate
to transfer switch and controller operation, the following terminol-
ogy is defined.
Available
A source is defined as "available" when it is within its undervolt-
age/underfrequency/overfrequency setpoint ranges for the nomi-
nal voltage and frequency setting.
Connected
Connected is defined as when the input is shorted by an external
contact or connection.
Failed or Fails
A source is defined as "failed" when it is outside of the applicable
voltage and frequency setpoint ranges for the nominal voltage and
frequency setting for a time exceeding 0.5 seconds after the time
delay emergency fail (TDEF) time delays expires.
Failsafe
Failsafe is a feature that prevents disconnection from the only
available power source and also forces a transfer or re-transfer
operation to the only available power source.
