General Description
Certifications and Compliance
TUV Rheinland EC Type Examination Certification
TUV Rheinland has certified the DriveGuard Safe Torque Off option, when
used in a PF70 or PF40P drive, is compliant with the requirements for
machines defined in Annex I of the EC Directive 2006/42/EC, and that it
complies with the requirements of the relevant standards listed below.
•
EN ISO 13849-1:2008 Safety of machinery - Safety related parts of
control systems - Part 1: General principles for design
(DriveGuard Safe Torque Off option + drive achieves Category 3 / PL
(d))
•
EN/IEC 61800-5-2:2007 Adjustable speed electrical power drive systems
- Part 5-2 Safety requirements - Functional
(DriveGuard Safe Torque Off option + drive achieves SIL CL 2)
•
EN/IEC 62061:2005 Safety of machinery - Functional safety of
safety-related electrical, electronic and programmable electronic control
systems
•
IEC 61508 Part 1-7:1998 and 2000 Functional safety of electrical/
electronic/programmable electronic safety-related systems - Parts 1-7
TUV also certifies that the DriveGuard Safe Torque Off option may be used
in applications up to Category 3 / PL (d) according to EN ISO 13849-1 and
SIL 2 according to EN/IEC 62061 / IEC 61508 / EN/IEC 61800-5-2.
TUV Rheinland certificate 01/205/0665/09 may be found at:
ATTENTION: Electrical Shock Hazard. Verify that all sources of AC and DC power are
de-energized and locked out or tagged out in accordance with the requirements of
ANSI/NFPA 70E, Part II.
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus
capacitors has discharged before performing any work on the drive. Measure the DC bus
voltage at the +DC and -DC terminals or test points (refer to your drive’s User Manual for
locations). The voltage must be zero.
ATTENTION: In Safe Torque Off mode, hazardous voltages may still be present at the
motor. To avoid an electric shock hazard, disconnect power to the motor and verify that
the voltage is zero before performing any work on the motor.
ATTENTION: In the event of the failure of two output IGBT's in the drive, when the
DriveGuard Safe Torque Off option has controlled the drive outputs to the off state, the
drive may provide energy for up to 180° of rotation in a 2-pole motor before torque
production in the motor ceases.
