‹ Main Circuit Terminal Functions
Main circuit terminal functions are summarized according to terminal symbols in Table 2.4. Wire the terminals
correctly for the desired purpose.
* 1. Connect the momentary power loss compensation unit. Do not connect power to these terminals.
* 2. Normally not used. Do not connect power to these terminals.
* 3. The MxC models CIMR-ACA4110 and 4160 do not have terminals r2, s2, t2, p1 and n1.
‹ Main Circuit Configurations
The main circuit configurations of the MxC are shown in Fig 2.7.
„ CIMR-ACA25P5 to 2045, 45P5 to 4160
* 1. Connect the momentary power loss compensation unit. Do not connect power to these terminals.
* 2. Normally not used. Do not connect power to these terminals.
* 3. The MxC models CIMR-ACA4110 and 4160 do not have terminals r2, s2, t2, p1 and n1.
Note: Control power is supplied internally from the main circuit power supply for all MxC models.
