6. System Installation
Input and output protections
When installing Sierra 10 inverter systems, UL489 listed AC upstream (input) and downstream (output) circuit breakers
are required. Refer section 6.4.6, page 26.
AC Input and Output
•
Branch circuit protection breaker should be provided in upstream switchgear regardless of any protective device
already installed at the input of the Sierra 10 system.
•
An appropriate branch protection should be provided between the Sierra 10 System and the load.
DC
•
An appropriate DC over current protection device should be installed at both Input and Output.
Output distribution should be structured to guarantee tripping segregation. Contact the manufacturer for
recommendations and calculation methodology.
•
Refer to section 6.4.6, page 26 for sizing protections and connecting cables. All cables must be copper rated
for min 90°C (194°F).
•
All cables must be C-UL-US or CSA Listed cables.
•
All cables lugs must be C-UL-US or CSA listed. They must be sized according to the rated current of the
converter system and to the customer terminal connection.
•
Wire all positions for future expansion.
•
Input AC / Output AC / Input DC / Signal cables shall be separated.
•
Cable crossings shall be done in 90 deg angles.
•
Empty converter positions shall be covered with blank module.
•
Sierra 10 system is designed for temperature controlled (40°C / 104°F max) and clean environments. The
presence of airborne particles such as urban dust, sand, metallic dust, and corrosive vapours is forbidden. Install
only in a relatively free of conductive contaminants environment.
6.1 Transformer and Generator Sizing
The inverter is capable of operating at 125% of rated capacity for 15 seconds.
•
Transformers supplying AC to the converter should be sized at a minimum of 1.25 times the kVA rating of the
converter to meet this requirement.
•
Generators supplying emergency AC to the building and to the converter should be sized at a minimum of two
times the kVA rating of the converter.
