Page 6: Environmental Limits
The SAFE TORQUE OFF function has been approved as meeting the requirements of EN954-1 category 3 for the prevention of unexpected starting of the drive. It may be used in a safety-related application. The system designer is responsible for ensuring that the complete system is safe and designed correctly according to the relevant safety standards. - Page 7 1.8.3 STOP function The STOP function does not remove dangerous voltages from the drive, the motor or any external option units. 1.8.4 Stored charge The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drive has been energised, the AC supply must be isolated at least ten minutes before work may continue.

Page 11: Mechanical Installation
Mechanical Installation Enclosure The drive is intended to be mounted in an enclosure which prevents access except by trained and authorized personnel, and which prevents the ingress of contamination. It is designed for use in an environment classified as pollution degree 2 in accordance with WARNING IEC 60664-1. - Page 12 Figure 3-2 Minimum mounting clearances 100mm (4in) *2mm (0.08in) 100mm (4in) *2mm clearance between drives to allow for mechanical tolerance. Digitax ST can be mounted using a DIN rail, either fixed at the top or the bottom of the drive (as illustrated in Figure 3-3). Two screws are required to fix the drive to the backplate at the opposite end to the DIN rail.

Page 17: Ground Leakage
Fuses/MCB The AC supply to the drive must be installed with suitable protection against overload and short circuits. Failure to observe this requirement will cause risk of fire. WARNING The drive must be grounded by a conductor sufficient to carry the prospective fault current in the event of a fault. -

4.3.1 Internal EMC filter It is recommended that the internal EMC filter is kept in place unless there is a specific reason for removing it. Special attention is required when using a DST120X model on an ungrounded supply (IT supply). In the event of a ground fault in the motor circuit the drive may not trip and the filter could be overstressed. - Page 19 4.3.2 Further EMC precautions Further EMC precautions are required if more stringent EMC emission requirements apply: • Operation in the first environment of EN 61800-3 • Conformity to the generic emission standards • Equipment which is sensitive to electrical interference operating nearby In this case it is necessary to use: •...

Page 21: Control Terminals
Control terminals The control circuits are isolated from the power circuits in the drive by basic insulation (single insulation) only. The installer must ensure that the external control circuits are insulated from human contact by at least one layer of insulation (supplementary insulation) rated for use at the AC supply voltage. - Page 22 4.4.1 Encoder connections Before using the encoder connectors for the first time, the break-outs need removing as shown in Figure 4-8. Figure 4-8 Access to encoder connections Break-outs After removing the break-outs, ensure that the ground tab is connected to ground. Do not remove break-out if the connections are not required.
