Note
The motor controller has to be installed in an electrical cabinet which provides a pollution
degree 2 environment.
The installation
orientation
is vertical to provide sufficient convection air flow through the
controller housing.
Comply with distances and clearances shown in figure 3-1.
Ensure that the motor controller is securely mounted with two M5 screws.
Do not insert anything into the ventilation openings of the controller.
Do not block the ventilation openings of the controller.
Only use attachments / accessories specified by the manufacturer.
The heat sink in the CMMB-AS-01, CMMB-AS-02 is cooled by natural air convection flow.
The heat sink in the CMMB-AS-04, CMMB-AS-07 is cooled by an internal fan.
Warning
In the case of use of an external brake resistor, provide adequate space around the brake
resistor since it can become very hot. No burnable material should touch or be close to the
brake resistor. Otherwise there is risk of fire, especially in case of a malfunction of the brake
chopper.

The fan of controller is replaceable. If a fan becomes defective, open the fan cover and replace it with a fan
with the same performance ratings. Technical requirements for the fan are as follows:
Power: 12VDC, 0.12A, size: 40 x 40 x10 mm
X3 : RS232 Connector
X5 : Encoder Connector
