CE Compliant Installation Guidelines
ASDs shall be installed in accordance with the following guidelines. See
selection information.
1. Filtering — An input filter shall be used with the ASD. A Schaffner input filter of the appropriate
rating shall be mounted next to the ASD. The filter output must be screened.
2. Mechanical — The ASD and the associated equipment shall be mounted on a flat metallic
backplane. Adequate ventilation must be provided for the filter. The filter output cable is to be
connected from the bottom of the filter to the ASD power input as is to be as short as possible.
Units received as an Open Chassis shall not be placed into operation until the unit is placed into an
approved enclosure that will protect personnel against electrical shock.
Opening and closing of enclosures or barriers shall be possible only with the use of a key or a tool.
3. Cabling — The power, filter, and motor cables shall be of the appropriate current rating. The
cables shall be connected in accordance with the guidelines of the manufacturer and the applicable
local and national agencies. A 4-core screened cable (such as RS 379-384) is to be used for the
power and earth connections to minimize RF emissions. Units that are sent to Europe require a
5-core screened cable to be used with a neutral conductor. Control cabling must be screened using
P/N RS 367-347 (360º gnd.) or a similar component.
4. Grounding — The main (input) ground shall be connected at the ground terminal provided on the
filter. The filter and motor shall be grounded at the ground terminals provided in the ASD.
5. Screening — The main (input) screen shall be connected to the metallic back-plane at the filter;
remove any finish coating as required. The screen over the filter output cables, the motor cable
screen, and the control wire screens must be connected to the ASD case using glands or conduit
connectors. The motor cable screen shall be connected to the motor case. When using a braking
resistor, the cabling between the resistor and ASD shall also be screened. This screen shall connect
to both the ASD enclosure and the resistor enclosure.
6. Shielding — Shielding terminations (clips, lugs, etc.) shall be connected to both the input and
output ends of the ASD.
7. RCD — Where residual-current-operated protective device (RCD) is used for protection in case of
direct or indirect contact, only RCD of type B is allowed on the supply side of this Electronic
Equipment (EE). Otherwise, another protective measure shall be applied, such as separation of the
EE from the environment by double or reinforced insulation, or isolation of the EE and the supply
system by a transformer.
8. Do Not connect two or more cables to the main circuit earth terminal of the ASD. If necessary,
install an additional earth terminal on the noise cut plate on which the ASD is installed and connect
another cable to it.
