2.1.2 Conformity with TÜV NRTL
This drive amplifier is approved under the TÜV reference number 028-713169202-000 and
falls under the category Power Conversion Equipment.
Explanations:
NRTL:
Approval according to standards of the United States in accordance with UL 61800-5-1
Approval according to national Canadian standards in accordance with C22.2 No.
274-13, 1st edition
NRTL Markings:

Maximum Altitude: 2000 m

Maximum Surrounding Air Temperature: IP20 45 °C, IP65 55 °C

These devices are intended to be used in a pollution degree 2 environment



Integral Solid State short circuit Protection

Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes

For Canada (CSA): Integral solid state short circuit protection does not provide branch
circuit protection. Branch circuit protection must be provided in accordance with the
Canadian Electrical Code, Part I

Use only UL listed Class G Fuse with a rating of minimum 300 Vdc and max fuse rating
of 25 A and an DC interrupt rating of 10 kA or higher, e.g. Bussmann SC-60.
Alternately use an UL listed fuse with an lower I²t rating of 25 kA and an Ip value of
10.5 kA

Tightening torque for factory wiring terminals: 0.5 Nm

These products are intended for operation within circuits not connected directly to the
supply mains (galvanically isolated from the supply, i.e. on transformer secondary).

This EUT is for use in non-hazardous locations, operated by qualified personell skilled
in its use.

This EUT shall be supplied with the specified rated voltages according to the user
manual.

The EUT fulfils the requirements of the tested standards only, if it is supplied with
a source that has a prospective short-circuit current of at least 5000 A.
2.1.3 Safety conformity (STO) in accordance with the Machinery Directive
The drive amplifier provides a two-channel, functionally safe STO function ( S afe T orque O ff).
The function disables the firing pulses of the power transistors so that the drive can be switched
safely to torque OFF.
The circuit design has been tested and subsequently assessed by TÜV Süd. According to that
assessment, the circuit design used for the
“Safe Torque Off” safety function in the simco drive
series of drive amplifiers is suitable for meeting the requirements for SIL 3 in accordance with
EN 61508 and category 4 PLe in accordance with EN ISO 13849-1:2015.
The subsystems (drive amplifiers) are fully described in terms of safety by the following
characteristics:
