Figure 5-17 Notes:
1. Each CRS-500 is shipped with two power supply modules installed in
the rear panel of the CSU – the AC IEC line input connector for each
power supply module contains the ON/OFF switch for that module. It
is recommended that both power supplies, connected to individual
power sources, are used for maximum reliability.
2. Each power supply module contains two fuses, one each for line and
neutral connections (or L1, L2 where appropriate). These are seated in
a fuse holder that is press-fit into the body of the module.
3. 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.
4. Comtech EF Data products’ auto-sensing power supplies do not
require any adjustments.
Connect the power cord. Do these steps:
1. Ensure that both power supply switches are in the OFF position before connecting the
power supply power cords.
2. Connect the female end of each supplied power cord into its power input (one to each
power input module).
3. Plug the male end of each power cord into its power source. Comtech EF Data
recommends that you connect each power cord to an alternate power source.
4. Do NOT turn the CRS-500 power switches ON until instructed to.
