• Keep control and power cabling separated. Minimize exposed (unscreened) cable.
• Use 3600 screened connections where possible.
CE Compliant Installation Guidelines
ASDs should be installed in accordance with the following guidelines.
1. Filtering — An input filter shall be used with the ASD. A Schaffner FN258 series input filter of the
appropriate rating shall be mounted next to the ASD.
2. Mechanical — The ASD and the associated equipment shall be mounted on a flat metallic
backplane. A minimum space of 5 cm (2 inches) shall be between the ASD and the filter to allow
for ventilation. The filter output cable is to be connected from the bottom of the filter to the ASD
power input and is to be the minimum length required for a connection. See
filter selection assistance.
Units received as an Open Chassis shall not be placed into operation until being placed into an
approved enclosure that will protect personnel against electrical shock.
Opening and closing of enclosures or barriers should 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. Control cabling must be screened using
P/N RS 367-347 or a similar component.
4. Grounding — The mains (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 mains (input) screen is to 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. 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 feinforced insulation, or isolation of the EE and the supply system by a
transformer.
