The minimum distance above and below the
module holder is required for cooling. Free
clearance space in front of the module holder
(“F”) is needed for the optional strain relief
brackets and for bending the IEEE 1394b and
SERCOS III cable(s). As a rule of thumb, 100
mm is sufficient. The free distance on the left
side (L) of the system housing must be suffi-
cient to access the connectors at those sides.
For convection cooled systems the system
housing must be installed vertically to allow
free air flow from bottom to the top. For forced
cooled systems it is allowed to install the sys-
tem housing horizontally.
Install the system housing on a vertical
metal surface, and ensure electrical contact be-
tween the system housing and this surface, ei-
ther by means of washers under the screw
heads or use the protective earth post on the
system housing with washers and nuts. Ensure
that there is electrical contact between the sys-
tem housing and the mounting base of all other
equipment installed on the metal frame or
mounting base.
Each protective earth connection may be
routed in the most convenient manner for the
equipment concerned. The NYCe 4000 system
put no extra requirements on the protective
earth wiring – no central earth point or similar
constraint.
10.3
Mechanical removal of the system housing
Make sure that all power supplies are switched
off before you remove the system housing.
Then disconnect the 24V System power
supply connector. Finally, disconnect all re-
maining connectors and protective earth con-
nections.
Remove the screws that mount the system
housing on the metal surface in the machine.
10.4
Protective Earth connection
For safety reasons, a protective earth connec-
tion via the threaded earth post is mandatory.
The protective earth connection must be
connected before any other cables are connect-
ed to the system housing.
The protective earth connection must be
realized using an as short as possible cable, or
better a braided band, with a faston at the sys-
tem housing side.
The protective earth connection is fastened
on the M5 threaded post on the system housing
using a ring, the faston with the cable or the
braided band, a spring washer and a nut, in that
order. Tighten the nut with a nut spanner.
You must adhere to the installation re-
quirements of your country.
10.5
Configuration
The left side of the system housing is the side
where the ‘24V System’ power supply con-
nector is located.
The slot on the left side is called ‘MCU’
and is a slot dedicated for the installation of the
Motion Control Unit (MCU).
The slot at the right side of the MCU module
in the module holder is called ‘SIII’ and is a
slot dedicated for the installation of the
NYM04.1-SE3-MAST-NY4150 SERCOS III
Master module.
10.6
System power supply connection
A power on/off switch or circuit breaker is not
part of the system housing. You must imple-
ment the following in the installation.
•
A switch or circuit breaker must be
included in the installation.
•
The switch or circuit breaker must be
placed at a suitable location and must be
easy accessible.
