Overview

EN 61800-5-1:2007/A1:2017 (IEC 61800-5-1:2007/A1:2016) is a CLC/CENELEC amendment addressing safety requirements for adjustable speed electrical power drive systems (PDS). It focuses on electrical, thermal and energy-related hazards for variable speed drives, drive modules (CDM/BDM) and associated motors. The amendment clarifies insulation, earthing, short‑circuit behaviour, motor overload protection and required tests to demonstrate compliance.

Key topics and technical requirements

• Scope: Safety requirements for adjustable speed power drive systems including electrical, thermal and energy aspects.
• Insulation and impulse voltage: Rules for selecting insulation levels for low-voltage circuits and guidance on impulse voltage and temporary overvoltages (no interpolation for impulse voltage).
• Earthing and system types: Consideration of TN, TT, IT and corner-earthed systems; specific design and separation requirements where one phase is earthed.
• Power output short‑circuit requirements: Mandatory evaluation of phase-to-phase and phase-to-earth short-circuits for each power output unless galvanic isolation applies.
• Motor overload & overtemperature protection: Options include thermal relays (IEC 60947-4-1), electronic motor overload protection, thermal memory/retention, speed-sensitive protection, thermal sensors or embedded motor thermal protection. Electronic protections must meet defined test clauses and shall not exceed specified limits.
• Electronic protection definitions: New terms in the amendment include electronic motor overload protection, electronic power output short-circuit protection circuitry, thermal memory and thermal memory retention.
• Testing and validation: Added tests include Electronic motor overload protection test, circuit functionality evaluation, short-circuit test procedures, and component breakdown testing with defined loop lengths and fault loops for test set-up.
• Documentation and information: Manufacturers must provide information on motor protection methods, thermal retention, and applicability when multiple motors share outputs.

Applications and who uses this standard

EN 61800-5-1:2007/A1:2017 is used by:

• Drive manufacturers and module (CDM/BDM/BDM) designers for product safety design and certification
• OEMs and system integrators implementing variable-speed drives in machines and industrial systems
• Safety engineers and compliance officers verifying conformity with electrical and thermal safety requirements
• Test laboratories and notified bodies conducting short‑circuit, overload and insulation testing
• Installers and maintenance teams referencing requirements for earthing and motor protection strategies

Practical uses include design validation of variable speed drives, specifying motor protection schemes, performing safety testing, and preparing compliance documentation for CE marking and international markets.

The short-circuit evaluation of each power output of the CDM/BDM shall include short-circuits
of both
• phase to phase, and
• each phase to earth.
If the CDM/BDM provides galvanic isolation between all power ports and a power output, then
evaluation of phase to earth short-circuits for that specific power output, and any additional
power outputs with galvanic isolation, is not necessary.
Compliance with the requirement of IEC 60364-4-41:2005/AMD1:— , Clause 411 and Annex D
is shown by
• testing according to 5.2.3.6.5, or
• supplementary protective equipotential bonding in accordance with IEC 60364-4-
41:2005/AMD1:—, 415.2.
The electronic power short-circuit protection circuitry relied on to demonstrate compliance
with the short-circuit test in 5.2.3.6.3 shall also comply with the requirement of 5.2.9.
NOTE IEC 60364-4-41:2005/AMD1:—, 411.3.2, provides more information about protection against indirect
contact in case of a short-circuit between hazardous live parts and protective earth.
Consideration shall be given to compliance with different type of system earthing (e.g. TN, TT,
IT or corner- earthed) as the short-circuit current to protective earth depends on the type of
system earthing.
NOTE Especially, the short-circuit fault current to earth is expected to be lower or equal to the rated output
current of the power output depending on system earthing.
For information requirements, see 6.3.7.
