Electrical Site RequirementsAC Power Requirements
TABLE A-2 AC Power Requirements
|
Electrical Element
|
Requirement
|
|
Voltage
|
100 VAC to 240 VAC (nominal)
|
|
Frequency
|
47-63 Hz
|
|
Input current
|
< 2.0 amps @ 100 VAC (150 Watts)
|
|
Max. input surge current
|
- 20 amps peak on a cold start (after the AC power has dropped off for >60 seconds) or on a restart (after the AC power has been removed for 200 milliseconds or longer)
- 100 amps peak on a warm start or a restart (after the AC power has been removed for <200 milliseconds but >20 milliseconds)
The surge current decays to normal operating current in less than 200 milliseconds. The surge current's decaying peaks are for less than 3 milliseconds duration in each half cycle.
|
Overcurrent Protection Requirements
|
Note - Overcurrent protection devices must meet applicable national and local electrical safety codes and be approved for the intended application.
|
- Overcurrent protection devices must be provided as part of each host equipment rack.
- Circuit breakers are located between the AC source and the array.
- Circuit breakers must not trip when presented with inrush current of 100 amps lasting 5 ms.
Disconnecting the Power for Servicing
You can disconnect the power for servicing in any of the following ways:
- Disconnect the power cord from the connector on the AC power supply at the back of the array.
- Turn off the circuit breakers in the rack where the array is mounted.
- Disconnect the main connector from the AC power source.
Ensure that all methods of disconnecting the power remain accessible after installation.
|
Caution - External filtering and surge suppression devices might be required on the power feeds where branch circuit electromagnetic characteristics are unknown.
|
DC Source Power Requirements
TABLE A-3 DC Power Requirements
|
Electrical Element
|
Requirement
|
|
Voltage
|
-48 VDC
|
|
Input current
|
< 4.0 amps @ -40 VDC (150 W)
|
|
Max. input surge current
|
- 20 amps peak on a cold start (after the DC power has dropped off for >60 seconds) or on a restart (after the DC power has been removed for 200 milliseconds or longer)
- 100 amps peak on a warm start or a restart (after the DC power has been removed for <200 milliseconds but >4.5 milliseconds.)
The surge current decays to normal operating current in less than 200 milliseconds.
|
DC power must be:
- Electrically isolated from any AC source
- Reliably connected to earth (the battery room positive bus is connected to ground)
- Capable of providing up to 200 watts of continuous power per feed pair
|
Note - The DC version of the array must be installed in a restricted access location. According to the intent of the National Electrical Code, a restricted access location is an area intended for qualified or trained personnel only and has access controlled by some sort of locking mechanism, such as a key lock or an access card system.
|
Overcurrent Protection Requirements
|
Note - Overcurrent protection devices must meet applicable national and local electrical safety codes and be approved for the intended application.
|
- Overcurrent protection devices must be provided as part of each host equipment rack.
- Circuit breakers must be located between the DC power source and the array. You should use two 10-amp, double-pole, fast trip, DC-rated circuit breakers for each power supply.
DC Supply and Ground Conductor Requirements
- Copper is the only suitable conductor material.
- Power supply connections through the input connector: 12 AWG (between the array and the circuit breaker). There are three conductors:
- -48V
- Ground connection to the power supply
- -48V Return
- System ground conductor: 6 AWG (to be connected to the chassis)
- Cable insulation rating: minimum of 75° C, low smoke fume (LSF), flame retardant
- Cable type to be one of the following:
- UL style 1028 or other UL 1581(VW-1) compliant equivalent
- IEEE 383 compliant
- IEEE 1202-1991 compliant
- Branch circuit cable insulation color: according to applicable National Electrical Codes
- Grounding cable insulation color: green and yellow
