3. Make sure the Total Cabinet PFs do not exceed the limits noted below. If either PF exceeds its
limit, adjust the PCB/telephone placement to meet the PF requirement.
Note Total +5VDC PF of PCBs must be less than 20 for each CTX100 cabinet and 40 for each
CTX670 cabinet. Total -24VDC PF of PCBs and telephones must be less than 45 for each
CTX100 cabinet and 85 for each CTX670 cabinet.
