A) During boot, the control box will check for an external 24V input. If none is available then it
will switch to the internal 24V supply.
B) The control box itself offers a 24V1.5A output (24_EX). If the 24V load exceeds 1.5A, it
enters Safe Mode and disables the 24V output.
C) EX24V provides an external 24V input port. If the load exceeds 1.5A an external power
supply can be used instead. The load on EX24V must not exceed 3.5A.
