APPENDIX D
3300 ACM MODEL/ORDERING INFORMATION
NOTE
In situations where the power supply to the 3300 ACM might be unstable, the P120DC or P240DC power
supply option should be used. These power supplies have much better immunity to power disturbances than
the standard linear power supply provided by the basic model or P240 option. Potentially unstable power
conditions include situations where:
1) there are frequent power disturbances or interruptions
2) the 3300 ACM is powered from a genset
3) the frequency can vary outside the specified limits of the basic model power supply or P240 option power
supply
