Before you start
Please be sure to observe the following notices and warnings before and during
electrical installation.
DANGER FROM ELECTRICAL TENSION!
Danger to life! Never wire or disconnect electrical connections while they are
live. Always disconnect the power before working on the device. Dangerously
high voltages ≥50 V (capacitor charge) may still be present 10 minutes after
the power is cut to the size 5 and size 6A. The discharge time depends on
the number of drives connected to the multi-axis system. So check that the
power has been cut! Hazardous voltage may be applied to the device, even if
the device does not show any visual signs or emit any audible signals. On the
size 5 and size 6A for example: with mains voltage applied to terminal X12 or
X21 and missing control v24 V on X9, X10. So check that no voltage is
connected!
ATTENTION!
Installation must only be carried out by qualified electricians who have
undergone instruction in the necessary accident prevention measures.
ATTENTION!
The device heats up in operation and at the heat sink may reach temperatures
of up to +100 °C (+212 °F). The connected chokes heat up in operation and
may reach temperatures of up to +145 °C (+293 °F). Keep a safe distance from
adjacent assemblies.

ATTENTION!
During installation, please avoid:
y
screws or cable residues dropping into the device;
y
penetration of damp into the device.
NOTE:
For installation of the Power Supply Unit within a Multi-Axis Servo Drive
System, be sure also to observe the Operation Manual for the Multi-Axis Servo
Drives.

Effective EMC installation
3.2.1
Cable type
y
Use shielded mains power, motor and signal cables as set out in Figure 3.7,
p. 30. Use a cable type with double copper braiding, with 60 - 70 %
coverage, for all shielded connections.
y
If very large cable cross-sections have to be installed, shielded single wires may
also be used instead of shielded cables.
ATTENTION!
Use only the supplied DC link cable for the electrical connections between the
devices. If other cables are used, Moog can provide no guarantee of stable
and safe operation.
