Safety & Compliance Forum

This part of IEC 61800 specifies requirements for adjustable speed electrical power drive systems (PDS) or their elements, with respect to electrical, thermal, fire, mechanical, energy and other relevant hazards. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electrical PDS which include the power conversion, basic drive module (BDM)/complete drive module (CDM) control, and a motor or motors.
Excluded are traction and electric vehicle BDM/CDM.
It applies to low-voltage adjustable speed electrical PDS intended to feed a motor or motors from a BDM/CDM connected to phase-to-phase voltages of up to and including 1,0 kV AC (50 Hz or 60 Hz) and up to and including 1,5 kV DC.
It also applies to high-voltage adjustable speed electrical PDS intended to feed a motor or motors from a BDM/CDM connected to phase-to-phase voltages of up to and including 35 kV AC (50 Hz or 60 Hz) and up to and including 52 kV DC.
NOTE 1 At the time of publication of this document, the technical limit for DC motors is 2,25 kV DC.
NOTE 2 Above voltage and frequency limits reflect the scope of IEC 61800-1 and IEC 61800-2.
NOTE 3 For adjustable speed electrical PDS not covered by the scope of this document, applicable requirements of other standards, for example IEC 62477-1 and IEC 62477-2, can be used.
This document also applies to PDS which intentionally emits or receives radio waves for the purpose of radio communication.
Motors for driven equipment (see Figure 1) complies with IEC 60034 (all parts).
NOTE 4 In some cases, safety requirements of the PDS (for example, protection against access to hazardous parts) can necessitate the use of special components and/or additional measures.

Summary of Topics

This new edition of ANSI/UL 61800-5-1 dated June 24, 2022 includes changes in requirements to the following:

– Alternate Means of Providing Installation Manual (Internet);

– Primary Rechargeable Battery Back-up;

– VFD Output Conductor Protection.

Please note that the national difference document incorporates all of the U.S. national differences for UL 61800-5-1. UL 61800-5-1 is based on IEC 61800-5-1, second edition (published July 2007).

Scope

This part of IEC 61800 specifies requirements for adjustable speed

power drive systems

, or their elements, with respect to electrical, thermal and energy safety considerations. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electric drive systems which include the power conversion, drive control, and motor or motors. Excluded are traction and electric vehicle drives. It applies to d.c. drive systems connected to line voltages up to 1 kV a.c., 50 Hz or 60 Hz and a.c. drive systems with converter input voltages up to 35 kV, 50 Hz or 60 Hz and output voltages up to 35 kV.

Other parts of IEC 61800 cover rating specifications, EMC, functional safety, etc.

The scope of this part of IEC 61800 does not include devices used as component parts of a

PDS

if they comply with the safety requirements of a relevant product standard for the same environment. For example, motors used in

PDS

shall comply with the relevant parts of IEC 60034.

Unless specifically stated, the requirements of this International Standard apply to all parts of the

PDS

, including the

CDM/BDM

(see ).

NOTE In some cases, safety requirements of the

PDS

(for example, protection against direct contact) can necessitate the use of special components and/or additional measures.

1.1 This document is only applicable to the power conversion and drive control equipment, servo drives and integral servo drive/motor combinations.

1.2 This standard applies to drives with an input rating up to and including 1,5 kV a.c. or d.c.

1.3 A component of a product covered by this standard shall comply with the requirements for that component. See Annex DVA for a list of additional standards covering components used in the products covered by this standard.

1.4 The scope includes

BDM/CDM/PDS

intended for connection to photovoltaic (PV) modules with output voltages not exceeding 1.5 kV DC.

This equipment is for use in ordinary locations in accordance with Articles 430 and 440 of the National Electrical Code, NFPA 70.

Specifications provided in other parts of the 61800 Series of Standards (for example EMC in part 3) apply only on agreement between the manufacturer and the customer.
