4.0 Operation

8. AC power sequence connector (cont.)

When mounting the amplifiers in a common rack, you should verify if the amplifiers' chassis

are sharing a common ground via the rack rails. To do this use a DMM (Digital Multi-Meter)

to measure the DC resistance between the rack rail and the chassis ground of each unit. Set

the DMM to measure DC resistance. Connect one probe to the rack rail and the other to the

chassis ground terminal on the SEQUENCE terminal of the Bose

2150. If the DC resis-

tance is greater than 0.2 ohms we recommend that you connect the chassis ground termi-

nals of the sequence connector together in a daisy chain as in Figure 8. Repeat this for

each Bose 2150 in the rack.

You do not have to daisy chain the chassis grounds together if there is less than a 0.2 ohm

resistance from the rail to the chassis ground of each unit. Let the rack rail be your chassis

ground path.

Using other amplifiers in the power sequence:

The Bose Models 1600 VI and 1800 VI can be used together with the Bose Model 2150 in a

sequenced configuration.

However, as the sequence terminal on the Bose

Model 1600 VI and 1800 VI has no chassis

ground connector, whenever this manual references the chassis ground connector, you

should replace it with some reliable ground connection point on the amplifier chassis, such

as a screw that is used in fastening the chassis parts together. A good example would be

the screws that retain the Bose input modules to the amplifier chassis. All other connec-

tions would be exactly as described in this discussion of sequencing hook-up procedures.

Note: For operation details regarding the Bose Model 1600 VI and the 1800 VI, please

consult the respective user guides provided with those amplifiers.
