3 Approvals

Certificates can be found in our Product Wiki on page Approvals.

3.1 Conformance with UL and cUL

This servo amplifier is listed under UL file number E217428.

UL (cUL)-certified servo amplifiers (Underwriters Laboratories Inc.) fulfil the relevant U.S.

and Canadian standard (in this case UL 840 and UL 508C).

This standard describes the fulfillment by design of minimum requirements for electrically

operated power conversion equipment, such as frequency converters and servo ampli-

fiers, which is intended to eliminate the risk of fire, electric shock, or injury to persons,

being caused by such equipment. The technical conformance with the U.S. and Canadian

standard is determined by an independent UL (cUL) inspector through the type testing

and regular checkups.

Apart from the notes on installation and safety in the documentation, the customer does

not have to observe any other points in direct connection with the UL (cUL)-certification of

the equipment.

UL 508C

UL 508C describes the fulfillment by design of minimum requirements for electrically ope-

rated power conversion equipment, such as frequency converters and servo amplifiers,

which is intended to eliminate the risk of fire being caused by such equipment.

UL 840

UL 840 describes the fulfillment by design of air and insulation creepage spacings for

electrical equipment and printed circuit boards.
