FAQ
-
Does the 2MLR-AC13-CC support hot-swapping in live systems?
No, this module does not support hot-swapping. Power must be turned off before installation or replacement. -
Can two 2MLR-AC13-CC modules operate in load-sharing mode?
Yes, two modules can be installed in parallel for active load sharing with redundancy. -
What is the protection level for input overvoltage?
The module includes internal surge protection and shuts down above 265 VAC. -
Does it feature reverse polarity protection on the output?
Yes, it includes reverse polarity protection to prevent damage from incorrect wiring. -
How is module fault status communicated to the control system?
Faults are indicated via a relay contact output and front-panel LED indicators. -
Is it compatible with third-party control platforms?
Yes, as long as the power requirements match, it can be used in non-Honeywell systems. -
Can the module withstand temporary inrush currents during system start-up?
Yes, it is designed to handle short-term peak loads without tripping. -
What type of fuse protection is provided inside the module?
It includes internal electronic fuses and current-limiting protection circuits. -
How does the module indicate that it is in a fault state?
A red fault LED is illuminated and the relay output switches to alert the system. -
Is external cooling required for the 2MLR-AC13-CC module?
No, the unit is convection-cooled and does not require additional cooling fans.
