EARTH GROUND WIRE LENGTH SHOULD BE HELD TO A MINIMUM.
USE THE HEAVIEST GAUGE WIRE AVAILABLE, UP TO 14 AWG (2.O MM
2
)
WITH A MINIMUM OF 18 AWG (1.O MM
2
), FOR EARTH GROUND WIRE.
REVERSE WIRES (INCREASE/DECREASE) TO REVERSE ACTION
(DIRECT/REVERSE).
MAKE SURE ALL TRANSFORMER/POWER WIRING IS AS SHOWN:
REVERSING TERMINATIONS WILL RESULT IN EQUIPMENT MALFUNCTION.
OPTIONAL 24 VAC WIRING TO NEXT CONTROLLER.
USE 1/4 IN (6 MM) PNEUMATIC TUBING. MINIMUM BRANCH LINE MUST BE
6 FT. (1.8M) OR LONGER.

E-Bus Termination Module
One E-Bus Termination Module, part number 209541B is required for a single terminated E-Bus or two E-Bus Termination
Module, part number 209541B for a double terminated E-Bus (see Fig. 21). Refer to the E-Bus Wiring Guidelines form, 74-
2865 for termination module placement rules.
