IMPORTANT

If the W7761A Device is used on Heating and Cooling Equipment (UL 1995 US only) devices and the transformer primary power is more than 150 volts, connect the transformer secondary to earth ground, see Fig. 14.

IMPORTANT

Notes on power wiring:

∙All field wiring must conform to local codes and ordinances.

∙To maintain NEC Class 2 and UL ratings, the installation must use transformers of 100 VA or less capacity.

∙For multiple controllers operating from a single transformer, the same side of the transformer secondary must be connected to the same input terminal in each device and the ground terminals (1 on the W7761A) must be connected to a verified earth ground for each device in the group. See Fig. 13. (Device configurations are not necessarily limited to three devices per transformer.)

∙For the W7761A Device (which has Triac outputs), all output devices must be powered from the same transformer as the one powering the Excel 10 W7761A Device.

∙Use the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2) for all power and earth ground connections.

∙To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the E-Bus communications loop.

∙Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.
