Option Wiring
1.
Select an external power supply.
When the option is first switched on, two times the normal current will flow through
the option for approximately 0.5 seconds. The option requires at least 3 A to
function properly.
WARNING! Electrical Shock Hazard. Use a battery or a double-reinforced UL Class 2 power supply to
provide power to the option. Using a different type of power supply may result in death or serious injury by
electrical shock or fire.
2.
Wire the Terminal Block TB1.
Wire the external power supply to terminal block TB1 on the option.
Use a flat-blade screwdriver to loosen the screws on the option plug, connect wiring
to the 24 V, 0, and FE terminals as shown in Figure 30 , then tighten the terminal
screws to hold wiring in place.
Refer to Wire Gauges and Tightening Torques on page 32 to confirm that the
proper tightening torque is applied to each terminal. Take particular precaution to
ensure that each wire is properly connected and wire insulation is not accidentally
pinched into electrical terminals.
NOTICE: Be sure to properly connect an external 24 Vdc power source to the power supply plug. Refer to
Option Specifications on page 37 for details. Improper wiring practices could damage the option due to
incorrect terminal connections.
