Installation Requirements
Install the SC1008 in a location that is accessible by qualified personnel for testing of the transfer
function using either a laser pointer (or similar) or the onboard test switch.
The SC1008 installs to a flat surface, has four conduit entry locations, and includes a universal
mounting plate with four mounting holes. Mounting and conduit hardware are provided by others.
Note: Suitable for use in other spaces used for environmental air (plenums) in accordance
with Article 300 of the National Electrical Code (NFPA 70).
Ambient Environment
NEMA Type 1 Enclosure suitable for installation location that conforms to the following ambient
environment:
•
0°C–40°C, 5–95% non–condensing humidity
Electrical Specification
Note: Continuous load current not to exceed 100% of the switch rating.
Use copper wire only, minimum 75°C conductors.
Normal and Emergency Rated Operational Voltage Input
•
120–277 VAC +/- 10%, 50/60 Hz
Load Rating
•
Supports a continuous load of up to 20A for tungsten and resistive load types, and supports
electronic ballast loads of up to 16A (80% of the switch rating)
-
Continuous load current not to exceed 100% of the switch rating
Transfer Initiation
•
When normal power is lost, meaning the voltage drops below 85 VRMS, the unit transfers the
output load to the emergency power source.
•
When normal power is restored, meaning the voltage rises above 90 VRMS, the unit transfers
the output load to the normal power source.
Short Circuit Current Rating
•
Short circuit capacity of 10kA
