Mechanical installation
The device is designed only for installation in a stationary switch cabinet. The switch
cabinet must as a minimum provide IP4x protection.
3.1 Notes for mechanical installation
WARNING! Risk of injury due to hot surfaces on the device!
•
Carelessness may result in serious burns.
The device and especially the heat sink heat up significantly during operation and can reach
temperatures of up to 100 °C. The chokes connected also heat up during operation and can
reach temperatures of up to 145 °C. Prior to starting work, make sure the device has cooled
down.
On touching there is a risk of burns to the skin. For this reason provide protection against
touching.
During mounting maintain an appropriate distance to neighbouring assemblies.
CAUTION!
Damage to the device due to incorrect installation conditions!
The device may suffer irreparable damage.
For this reason
• Moisture must not be allowed to enter the device
• There must not be any aggressive or conductive substances in the ambient air
• Foreign bodies such as drilling chips, screws, washers etc. must not be allowed to fall into
the device
• The ventilation openings must not covered
NOTe:
The supply unit must not be installed in areas where it would be permanently
exposed to vibration. You will find further information in Table A.17 in the
appendix.
NOTe:
On installing the supply unit in a ServoOne multi-axis system, it is also
imperative the operation manual for the DC axis controllers is followed.
3.1.1
Arrangement and mounting
The following guidelines apply in principle to the supply unit and DC axis controller:
y
The backing plate must be well-earthed.
y
To attain the best result for effective EMC installation you should use a
chromated or galvanised backing plate. If backing plates are varnished, remove
the coating from the contact area! The devices have a galvanised sheet steel
back panel.
y
Maximum pollution degree 2 according to EN 60664-1. You will find further
information on ambient conditions in Table A.15 in the appendix.
y
Cooling air must be able to flow through the device without restriction.
y
On installation in cabinets with convection (= heat loss is dissipated to the
outside via the switch cabinet walls), always fit an internal air circulation fan.
y
Devices with different housing variants (wall mounting and liquid cooling) can be
mounted side-by-side in any combination.
y
Devices with the liquid cooling housing variant have a spacer on the rear in
place of the heat sink. As a consequence it is possible to connect devices with
the wall mounting housing variant using pre-assembled DC link cables without
additional compensation measures in relation to the device depth.
y
Between the devices, minimum distances as per Table 3.1 and Table 3.2 are to
be met.
y
The maximum distance between the devices up to size BG5 is defined by the
pre-assembled connection cables supplied and is 2 mm (for exceptions see
Table 3.1 and Table 3.2).
