20 CZM-1s, 4 ohms max. Multiple Class B
power connections can be used if you do not
exceed the ratings above (40 CZM-1s max
and 4 ohms per run max). For example, you
could have four individual Class B power runs,
for a total of 40 devices (for example, 12, 8, 6,
and 14 CZM-1s), with each of the four runs not
exceeding 4 ohms resistance.
T-tapping is allowed, provided the total resis-
tance of all wires does not exceed 4 ohms.
6. Refer to Figures 9 and 10 for wiring instruc-
tions for the PS-5A.
MOI-7 Power (P9)
The PSR-1 may be used in standalone mode as
the power supply for the MOI-7. In this configura-
tion the MOI-7 and the PSR-1 must be in the
same enclosure. A separate 5V output is provided
for the MOI-7. The PSR-1 local trouble contact
must also be connected as a means of reporting
PSR-1 troubles to the MXL. See Figure 11 for the
wiring diagram.
See Figure 12 if the MOI-7 is in a separate enclo-
sure. In this configuration do not use the 5V
power on P9. A separate PS-5A must be in-
cluded
in the remote enclosure with the MOI-7.
