Mounting distances CMMT-AS-...-3A (1-phase)
The servo drives of the CMMTAS series can be arrayed next to each other. When
arraying devices, the required minimum distance must be maintained so that the
heat generated during operation can be removed by allowing sufficient air flow.

1) To ensure that clearance H2 is observed and that the motor and encoder cables are routed in the optimum
manner on the bottom of the housing, an installation clearance of 150 mm is recommended!
Tab. 11 Mounting distances and installation clearance
This means that a minimum lateral distance of 2 mm (52 mm – 50 mm) must be
observed in relation to neighbouring CMMTAS devices.
For adjacent thirdparty devices, Festo recommends a distance of at least 10 mm
(surface temperature of thirdparty device max. 40 °C). The double mating plug
for crosswiring of the connection [X9A] protrudes by approx. 6 … 7 mm over the
right side of the device. However, this does not create an obstacle for arraying
additional CMMTAS.

Installation
Assembly instructions
–
Use a control cabinet with degree of protection IP54 or higher.
–
Always install device vertically in the control cabinet (mains supply lines [X9A]
point upwards).
–
Screw device flat to a sufficiently stable mounting surface so that good heat
transfer from the cooling element to the mounting surface is ensured
(e.g. screw to the rear wall of the control cabinet).
–
Maintain minimum distances and installation clearance to ensure sufficient
air flow. The surrounding air in the control cabinet must be able to flow
through the device from bottom to top without hindrance.
–
Take into account the required clearance for the wiring (connecting cables of
the device must be routed from above and from the front).
–
Do not mount any temperaturesensitive components near the device. The
device can become very hot during operation (switchoff temperature of the
temperature monitoring
è
Technical data).
–
When assembling several devices in a device compound, consider general
rules for crosswiring. For intermediate circuit coupling, higherpower devices
must be placed closer to the mains supply.
To enable attachment to the rear panel of the control cabinet, the servo drive
cooling element has a slot on the top in the shape of a keyhole and an ordinary
slot on the bottom.
Assembly of the servo drive
WARNING!
Danger of burns through hot escaping gases and hot surfaces.
In case of error, incorrect wiring or incorrect polarity of the connections [X9A],
[X9B] and [X6A], internal components can be overloaded. High temperatures can
develop and hot gases can be released.
•
Have an authorised electrician perform the installation according to the docu
mentation.
WARNING!
Danger of burns from hot housing surfaces.
Metallic housing parts can accept high temperatures in operation. In particular,
the braking resistor installed in the profile on the back side can become very hot.
Contact with metal housing parts can cause burn injuries.
•
Do not touch metallic housing parts.
•
After the power supply is switched off, let the device cool off to room temper
ature.
•
Fasten the servo drive to the rear wall of the control cabinet with suitable
screws while complying with the assembly instructions.

Safety
WARNING!
Risk of injury from electric shock.
Contact with live parts at the power connections [X6A], [X9A] and [X9B] can result
in severe injuries or death.
•
Do not pull out power supply plugs while live.
•
Before touching, wait at least 5 minutes after switching off the load voltage to
allow the intermediate circuit to discharge.
WARNING!
Risk of injury from electric shock.
The leakage current of the device to earth (PE) is
>
3.5 mA AC or 10 mA DC.
Touching the device housing if there is a fault can result in serious injuries or
death.
Before commissioning, also for brief measuring and test purposes:
•
Connect PE connection on the mains side at the following positions:
–
Protective conductor connection (earthing screw) of the housing
–
PE pin of the connection [X9A] (power supply)
The cross section of the PE conductor must be at least equal to the cross
section of the line conductor L at [X9A].
•
Connect motor cable to connection [X6A] and the shield of the motor cable on
the front side to PE via the shield clamp of the servo drive.
•
Connect all additional PE conductors for the connections used.
•
Observe the regulations of EN 602041 for the protective earthing.
WARNING!
Danger of burns through hot escaping gases and hot surfaces.
In case of error, incorrect wiring or incorrect polarity of the connections [X9A],
[X9B] and [X6A], internal components can be overloaded. High temperatures can
develop and hot gases can be released.
•
Have an authorised electrician perform the installation according to the docu
mentation.
