Since the end of 2007, device approval according to IEC Directive „Adjustable speed electrical power drive systems – Part 5-1:
Safety requirements" requires additional distances between test finger and life parts according to the line-to-earth voltage – in order to achieve additional finger safety (for example, + 3 mm for 400 V-TN systems (line-to-earth voltage = 230 V), or + 5 mm for 400 V-IT systems (line-to-earth voltage up to 400 V in case of error)). An additional cover is required for the wiring section of a device if the connection system does not fulfil these requirements. The OMNIMATE POWER HP product line already complies with the stricter IEC requirements for additional finger safety.
It goes without saying that plug-in connectors rated for 600 V must be approved according the UL 1059 component standard, if determined for the us market. But, beyond the component directives, it is about to still meet the requirements of the end use standard (e.g. UL 508C), when the component is an integrated part of the device, if one wants to avoid comprimises that lead to restrictions like just being „recognized" but not „listed", or redesigns and additional measures such as coatings and covers. That is why the OMNIMATE POWER series provides sufficient creepages and clearances related to the surrounding device. The OMNIMATE POWER HP product line already complies with the UL requirements for 600 V creepage and clearance distances.
