AFE in IP20 2500 MCC Style Enclosure—Installation/Wiring
Table 7 - Door Control Box I/O Terminal Designations for AFE in IP20 2500 MCC Style Enclosure
ATTENTION: For the AFE in the IP20 2500 MCC Style enclosure, Digital Inputs
1, 3, 4, and 5, and Digital Outputs 1 and 2 are factory wired and programmed
to operate from the controls on the front of the enclosure. Digital Output 3 is
programmable and factory wired for +24V DC only. Do not change the wiring
and programming for those digital inputs and outputs, or it will result in
malfunction of the system.

(1) Important: Input must be configured with a jumper. AFE damage can occur if jumper is not installed properly. See

(2) These inputs/outputs are dependant on a number of parameters.
Isolated
(3)
, bipolar, differential, 9 bit & sign,
88k ohm input impedance. A jumper (see
) selects 0-10V, ±10V, or 4-20 mA.
Default: 0-10V (Ri = 200k ohm), 4-20 mA
(Ri = 100 ohm).
(3) Differential Isolation - External source must be maintained at less than 160V with respect to PE. Input provides high common mode
immunity.

(5) Contacts in un-powered state. Any relay programmed as Fault or Alarm energizes (pick up) when power is applied to the AFE, and
de-energizes (drop out) when a fault or alarm exists. Relays selected for other functions energize only when that condition exists
and de-energizes when the condition is removed.
