2.4 Precautions when Installing RMU inside the Controller
In the use of this unit, the following requirements of each standard.
The RMU is constructed to be installed inside the robot controller.
2.4.1 Low-Voltage Directive requirements to be satisfied (compliance with
EN50178)
■
Hermetically sealed structure
IMPORTANT
The RMU20 is designed to be used in an environment with "degree 2 pollution".
When installing RMU20 in the robot controller, use a hermetically sealed structure for the
controller, and take measures to make it dust-proof and water-proof. To do this,
completely close the door of the controller, and lock in the door key.
The degree of pollution of 2 is defined as follows.
“Environments in which electrically conductive dust and dirt are not normally generated, but in which electrical
conduction may be temporarily caused by the build-up of dust and dirt; approximate environments inside a
control panel equivalent to IP54 in the control rooms or on the floors of factories.”
■
Power supply
IMPORTANT
The RMU20 is installed inside the robot controller for use.
The power supply with overvoltage category I must be used. Category I denotes a power
supply whose voltage has been reduced using a transformer by 3 or more stages from
the power distribution grid.
Category III Category II Category I Category IV
2.4.2 EMC Directive requirements to be satisfied (compliance with
EN61326-3-1)
Implement the following items without fail in order to comply with the requirements of the EMC Directive.
However, doing so does not guarantee that the entire system in which the RMU is installed complies with the
EMC Directive.
To determine whether the entire system complies with the directive, conduct tests on it.
■
24V power supply
IMPORTANT
24V power supply supplied to the RMU is recommended to use the following. (Please
use the power supply of an equal specification when you use a different power supply.)
