5.5 Switch Configuration
5.5.1 Switch Power
Connect the power cords as follows:
Step Procedure
1 Ensure that both power supply switches are in the off position before connecting the
power supply power cords.
2 Each CRS-300 is supplied with two power cords. Connect the female end of the
supplied power cords (one to each power supply power input).
3 Plug both power cords into the power source(s).
Note: The auto-sensing power supplies do not require any adjustments.
4 Once all system connections are in place, turn both power supplies ON.
The IEC line input connector for each power supply card contains the ON/OFF switch for that
card. Each CRS-300 is shipped with two power supplies, and it is recommended that both be used
for maximum reliability.
If only one power supply card is used, mask the fault for the unused power supply as follows:
Step Procedure
1 Go to the CONFIG Æ OPTIONS Æ MASKS Æ SW-ALARMS menu.
2 Select to mask the unused power supply.
Note : The power supplies contain two fuses, one each for line and neutral connections (or L1, L2
where appropriate). These are contained within the body of the connector, behind the small
plastic flap.
WARNING
For continued operator safety, always replace the fuses with the correct type and
rating. For 115/230 volt AC operation, use T1A (slow-blow) 20 mm fuses.
