DC Discussions – We agreed that …

LIGO-G1000552-V8 16

•I/O Extenders will be powered separately from Electronics Chasses. This will permit the electronics to be turned off and on without interference to the I/O Extenders.

•3-conductor extension cables will be used between the DC Power Racks and the Electronics Racks. This will provide one return per set (+/-) of supplies.

•All DC Power Supply returns will be tied together (bonded) at the DC Power Rack to avoid ground loops.

•DC Power Racks will all be tied to technical ground.

•Shielding DC extension cables (from DC Power Racks to Electronics Racks) is not necessary.

•Non-standard (18/24) voltages should be a multi-conductor cable solution similar to this solution. See DC jacket colors for voltage conventions.

•Remote sensing will not be used. The length of cable is too great for effective control.

DC Wiring Color Convention

LIGO-G1000552-V8 17

Either single conductor wiring or multi-conductor cabling may be called for. These charts show the DC color code for either the single conductor wiring or the multi-conductor cabling.
