3.11.3 Electrical Specifications
Refer to the individual component’s specifications.
Electromagnetic compliance (EMC)
The equipment contained in the power system complies with the specifications of FCC, Part 15,
Subpart B for class A equipment, CSA 108.8 for class A and CISPR 22 for class A.
Electrostatic discharge (ESD) immunity

3.11.4 Environmental Specifications
Operating
Transportation
During transportation the equipment may be subjected to the following conditions without damage:
Storage
Heat dissipation
A Helios DC System 4000/48 rectifier cabinet equipped with six Helios Rectifier 200I/48 or 200E/
48 will dissipate a maximum of 8,010 watts or 27,350 Btu/hr.
3.11.5 Floor and Point Loading
The floor loading is based on a footprint of 600 mm x 600 mm (23.6 in. x 23.6 in.) plus a 30-inch
aisle width (15 inches front and rear).
The point loading is based on distributing the cabinet weight over four shims, each with an
assumed area of 25.8 cm
2
(4 in.
2
).
See Figure 1 for a typical system configuration for floor and point loading calculations.
Temperature: 0° to +50°C (32° to 122°F)
Humidity: 0 to 95% non-condensing
Altitude: Sea level to 2134 m (7000 ft)
NOTE
Do NOT ship with the rectifiers installed in the rectifier cabinet(s).
Temperature: -50° to +75°C (-58° to +167°F)
Humidity: 0 to 95% (non condensing) 4kPa max. WVP for 10 days
Vibration: TR-NWT-000063 section 5.4.4 Transportation Vibration (packaged equipment)
Shock: TR-NWT-000063, Section 5.4.1 Handling Drop Tests, and Section 5.4.3 Installation Shop Tests
Temperature: -50° to +75°C (-58° to +167°F)
Humidity: 0 to 95% (non condensing) 4kPa max. WVP for 10 days
