The environment into which any electronic control system is
installed can effect its operation. Danaher Motion recommends that
the SERVOSTAR system be operated and stored under the
environmental conditions stated in the product specification tables.
The system may be operated in higher temperature ambient
conditions with a derating applied. Contact Danaher Motion C.2

Attention to proper installation and field wiring are of prime
importance to ensure long-term and trouble-free operation. Users
should familiarize themselves with and follow the installation and
wiring instructions listed in this section. In addition to these
practices, some localities and industries may require applicable
electrical and safety codes, laws, and standards.
Particular care should be used when layout of an enclosure is
designed. Efforts to separate power wires from small signal wires
should be taken. The following guidelines highlight some important
wiring practices to implement:
− Control and signal cables must be separated from power and
motor cables. Distance of 20 cm (8 in.) is sufficient in most
cases.
− Control and signal cables must be shielded to reduce the
effects of radiated interference.
− Where control cables must cross power or motor cables, they
should cross at a 90º angle, if possible. This reduces the field
coupling effect.
4.1 Enclosure
The Danaher Motion SERVOSTAR series of electronic system
components are designed for panel assembly, which should be
mounted in a metallic enclosure. Enclosures are supplied by the
manufacturers of the final product and must meet the
environmental IP rating of the end product. To ensure proper
grounding (and to optimize EMC), the enclosure should have
continuous ground continuity maintained between all metal panels.
This ground continuity is intended to be both a safety ground and a
high frequency ground. The units should be mounted on a back
plane, which is installed into the enclosure. Ideally, the back plane
should be an unpainted metallic surface to optimize electrical
bonding of the frame and provide the lowest possible impedance
path to earth ground. These enclosures also provide added safety.
