Instruction Manual - Magnetrol International

➀ With housing drain, CSA drops Group E and FM drops Group C.
➁ Models B10 and B15 with “HS” switches and all Model C10 and C15 are not ATEX approved.
➂ IEC Installation Instructions:
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use
and correctly installed.
For ambient temperatures above +55° C or for process temperatures above +150° C, suitable
heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
Special conditions for safe use:
When the equipment is installed in process temperatures higher than +85° C the temperature
classification must be reduced according to the following table as per IEC60079-0.
