Rectifier Module Insertion and Removal
Rectifier modules are shipped separately. They must be
plugged in to the system prior to power-up.
The rectifier modules are designed for “hot plug-and-play”. It is safe to insert and remove modules at any
time, even when the system is loaded.
The rectifier modules are self-addressing, meaning that no setup
is required for the EM4x controller to determine rectifier
addressing.
IMPORTANT:
if a rectifier is removed from the system and then
plugged into another rectifier slot, you must wait for the red LED
to extinguish (this clears the address setting in the EPROM).
When inserting the module, ensure that it is pressed hard into
the system. The locking button should click. See
Figure 14.
To remove the module, press the locking button while pulling on
the “handle” that is integrated into the front panel. See
Figure 15
.
Check that any blank rectifier slots have the rectifier blank panel
inserted to prevent air back-flow.
