SECTION 3: WIRING AND INSTALLATION T200 User's Manual
PAGE 3-21
3.2.1 CE Items for Mechanical Installation
Additional electromagnetic compatibility (EMC) measures must be installed
on equipment associated with the T200 Servo-drive. The following measures
must be implemented:
• All external Regen (Regenerative circuit) resistors used with the T200
must be installed in enclosures which provide a degree of ingress
protection against liquids and objects of at least IP54 and which are
accessible to technically qualified service or maintenance persons only.
Protection against electric shock must be maintained when installing
these resistors.
• Use shielded cable to connect the external regen resistor (if installed) to
the T200 power supply. The length of this cable should be as short as
possible. The shields of these cables should be earthed to Chassis Earth
using the optional EMC Bracket kit or the panel earth bar. Alternatively,
if the cable is required to pass through an enclosure panel earthed to
Chassis Earth, the shield may be earthed to the panel by use of a 360
degree metal cable gland.
• Cables supplying external d.c. supply voltages to the T200 Series Servo-
drives (for example, the 24 Vd.c. supply) must be as short as possible.
The supply wires should be twisted together or alternatively shielded
cable should be used.
• Cables connecting the 325V D.C. Bus from the T200 Power Supply to
other T200 Servo-drives must be as short as possible. The supply wires
should be twisted together where possible or shielded cables should be
used.
• Motor power cables must be shielded with the cable shield securely
connected to Chassis Earth at both ends of the cable. At the T200 Servo-
drive end of the cable, the shield should be earthed using the optional
EMC Bracket kit.
• Motor resolver/signal cables must be shielded with the cable shield
securely connected to Chassis Earth at both ends of the cable.
• Signal cables must be shielded with the cable shield securely connected
to make a good HF earth bond to Chassis Earth at both ends of the cable.
Further details for the correct installation and shielding of cables and
conductors are given in Section 2.
- Enclosure or cabinet temperature control is critical for
performance, reliability and life of electrical components. Maintaining a
uniform temperature (check for hot spots) within the specified values for the
equipment will prevent premature failure due to temperature stress.
