and as an aid to builders of complex system, the emission limits and immunity levels associated with category C3 have been applied.
Parker SSD Drives' certification (DoC) is supported by tests undertaken in accordance with harmonised standard BS EN61800-3
United States of America & Canada
Compliance
The US have many municipalities that have laws, codes or regulations which require a product to be tested by a nationally recognized testing
laboratory before it can be sold in their area. Parker SSD Drives adopt the nationally recognised Underwriters Laboratories (UL) mark to demonstrate
compliance.
Products are also certified for the Canadian market obtained through UL and their memorandum of understanding with the Canadian Standards
Agency (CSA).
Parker SSD Drives obtain product certification to UL508C “Power Conversion Equipment” for the US market, and C22.2 No.14 “Industrial
Control Equipment” for the Canadian market.
Conditions for Compliance with UL508c
Solid-State Motor Overload Protection
NOTE An external motor overload protective device must be provided by the installer.
The maximum internal overload protection level (current limit) is 150% for 30 seconds and 200% for 10 seconds.
Motor overload protection is provided by means of the thermal device in the motor winding. This protection cannot be evaluated by UL, hence it is the
responsibility of the installer and/or the local inspector to determine whether the overload protection is in compliance with the National Electrical Code
or Local Code requirements.
