Watlow Series PD ■ 11 ■ Chapter 2 Install and Wire

Warning:

Use National Electric (NEC) or

other country-specific standard

wiring and safety practices when

wiring and connecting this con-

troller to a power source and to

electrical sensors or peripheral

devices. Failure to do so may re-

sult in damage to equipment and

property, and/or injury or loss of

life.

Note: Current transformer (CT)

must be purchased separately.

Note: A current transformer input

cannot be associated with a

process output on Output 1 or 3.

Note: Install a 1kΩ pull-down

resistor for each digital in-

put using voltage inputs.

Note: Install a 10kΩ pull-up re-

sistor for each digital input

using contact closure in-

puts.
