DM4610 - FAN module with Air Filter.
Despite there are fan protection shields, take some care to manipulate the ventilation module. It
must be pulled through the structure metal from the frontal part only. Besides, it requires attention
regarding chains, bracelets and other objects small enough to pass through the ventilation rails.

ODULE
The DM4610 uses three fans. It is possible to operate at different speeds, depending on the environment’s
temperature, configuration and number of interfaces installed in the system, which also reduces the ambient
noise and increases the service life of the fans.
When the system is active, the FAN module operates in maximum rotation, until the DM4610 software
determines the initialization process. Once started, the DM4610 controls the speed of the fans according to
the system temperature.
In failure case, an appropriate alarm is generated so that the operator can request the replacement.

IR FILTER
Responsible for filtering the air used to cool the modules. To ensure a correct fit, the frame containing the
filter is fixed with two screws in the module FAN.
In this position, all the air pumped by the FAN module from the external environmental passes mandatorily
through the air filter.
For more details about the installation of the filter and cleaning, check on

NFORMATION
The DM4610 allows two power supply options for feed the basic chassis, PSU 120 AC and PSU 120 DC as
described below.
It is possible to work with both models simultaneously and redundantly on the same chassis.
These power supply modules have exclusive slot positions on DM4610 chassis, called PSU1 and PSU2, with
the feed inlets in the rear of the chassis.
