PATH: SETTINGS SYSTEM SETUP
 CURRENT
 TERMINAL F1
This menu configures the AC current inputs. Upon power up, the B90 recognizes all the AC modules loaded in its chassis
and populates the above menu accordingly.
The current terminals are denoted in the following format: Xa, where X = {F, L, S} and a = (1, 2,..., 8}. X represents the
chassis slot containing the AC input module and a represents the AC channel of each module. For example, a B90 unit
containing the F8H and L8K modules displays the following current inputs for configuration: F1, F2, F3, F4, F5, F6, F7, F8,
L1, L2, L3, L4, L5, L6, and L7.

This menu configures the AC voltage inputs. Upon power up, the B90 recognizes all the AC modules loaded in its chassis
and populates the above menu accordingly.
The voltage terminals are denoted in the following format: Xa, where X = {F, L, S} and a = (5, 6, 7, 8}. X represents the
chassis slot containing the AC input module and a represents the AC channel of each module. For example, a B90 unit
containing the F8F and L8K modules displays the following voltage inputs: F5, F6, F7, F8, and L8.
