RTS 2nd Generation SERVO AMPLIFIER SAFETY Servodrives present two main types of hazard : - Electrical hazard Servoamplifiers may contain non-insulated live AC or DC components. Users are advised to guard against access to live parts before installing the equipment.
Page 4 RTS 2nd Generation SERVO AMPLIFIER Upon delivery All servoamplifiers are thoroughly inspected during manufacture and tested at length for bugs before shipment. • Unpack the servoamplifier carefully and check it is in good condition. • Also check that data on the manufacturer's plate comries with data on the order acknowledgement.

RTS 2nd Generation SERVO AMPLIFIER 1. GENERAL The RTS servo amplifier is designed for four-quadrant control of DC servo motors up to mechanical powers of 2500 W. It incorporates power and chopping supplies, including the energy dissipation resistor for some versions.
Page 6: Technical Specifications
RTS 2nd Generation SERVO AMPLIFIER - COMPLIANCE WITH STANDARDS RTS bears the CE mark under European Directive 89/336/EEC as amended by Directive 93/68/EEC on electromagnetic compatibility. This European Directive refers to the harmonised generic standards EN50081-2 of December 1993 (Electrical Compatibility - Generic Standard for Emissions - Industrial Environments) and EN50082-2 of June 1995 (Electromagnetic Compatibility - Generic Standard for Immunity - Industrial Environments).

Racks are available with or without ventilation, while RTS wall-mounted versions have individual ventilation where required (RTS 12/24-130T, RTS 20/40-130T and RTS 16/32-190T). Unventilated racks are for RTS 3/10-40M only.

3.2 Labelling RTS SERVO AMPLIFIER IDENTIFICATION Each RTS servo amplifier has an identification label affixed either on the metal plate at the rear for wall-mounted versions or on the side of the heat sink for rack versions. The information should be recorded and stored as with the information about the corresponding servo motor.
Page 24: Electrical Connections
The drive will then be earthed via a low impedance link between the potential reference plate and the earth screw at the back of the RTS. If this link exceeds 30 cm, a flat braid should be used instead of a conventional lead.

The extra choke is connected between the RTS and the servo motor, as near as possible to the RTS. It must be used when the servo motor choke is less than the values in the table on page 7. It should also be used when the RTS and servo motor are more than 50 m apart (or 25 m where shielded cable is used).
