Note: Wiring from the system to the products IT controls can either be installed in conduits or installed without conduits if the wires are in accordance with Article 725 of the National Electrical Code (NFPA 70) and Section 16 of the Canadian Electrical Code (C22.1).

Caution: Only Class 2 circuits rated 30 V or less can be connected to terminals 1–8. Class 2 circuits are defined in Article 725 of the National Electrical Code (NFPA 70) and Section 16 of the Canadian Electrical Code (C22.1). A Class 2 circuit is a source having limited voltage and energy capacity as follows:

A. If an Inherently Limited Power Source, voltage is limited to 30 VAC or 30 VDC, and energy is limited to 8 A.

B. If not an Inherently Limited Power Source, voltage is limited to 30 VAC or 30 VDC, energy is limited to 250 VA, and current is limited to 1000/Vmax. The fuse is limited to 5 A if maximum voltage is 20 V, or 100/Vmax if voltage is greater than 20 V but less than 30 V.
