Installing FastIron GS and FastIron GS-STK Devices
Installation precautions
Ensure that the device does not overload the power circuits, wiring, and over-current protection. To
determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices
installed on the same circuit as the device. Compare this total with the rating limit for the circuit. The
maximum ampere ratings are usually printed on the devices near the input power connectors.
All devices with DC power supplies are intended for installation in restricted access areas only. A
restricted access area is where access can be gained only by service personnel through the use of a
special tool, lock and key, or other means of security, and is controlled by the authority responsible for the
location.
For a DC system (DC power supply part number RPSDC-FGS), use a grounding wire of at least 10
American Wire Gauge (AWG). The 10 AWG wire should be attached to an agency-approved crimp
connector, crimped with the proper tool.
For the DC input circuit to the system (DC power supply part number RPSDC-FGS), make sure there is a
Listed 30 amp circuit breaker, minimum -48Vdc, double pole, on the input to the terminal block. The
input wiring for connection to the product should be Listed copper wire, 10 AWG, marked VW-1, and rated
minimum 90 degrees Celsius.
Make sure you insert the power supply right-side up. It is possible to insert the supply upside down,
although the supply will not engage with the power backplane when upside down. The power supply is
right-side up when the power connector is on the left and the fan vent is on the right.
Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged. (The device can be running while a power
supply is being installed or removed, but the power supply itself should not be connected to a power
source.)
