Notes:
1. The non-intrinsically safe terminals (power rail) must not be connected to any device which uses or generates more
than 250 Vrms or dc unless it has been determined that the voltage has been adequately isolated.
2. In the USA the installation must meet the requirements of the National Electrical Code, NFPA 70. article 504 resp.
article 505 and ANSI / ISA RP 12.6 . In Canada observe the Canadian Electrical Code.
