All ATV58 TRX Type E, Type F, Type H, and Type N models have the same 
control terminals, shown in the figure to the left. The locations of the control 
terminals varies from model to model as shown on pages 18 and 19.

The control terminal strip contains two pull-apart terminal blocks, one for the 
relay outputs and one for the low-level inputs and outputs. The S terminal is 
used for the shield connection. Maximum wire size for all control terminals is 
14 AWG (1.5 mm

2

). Tightening torque is 3.5 lb-in (0.4 N•m). The 

characteristics of the control terminals are shown in the table below.

R1A
R1B
R1C

R1A to R1C is a N.O. contact. When the 
drive controller is powered with no fault, 
the contact is closed.

R1B to R1C is a N.C. contact. When the 
drive controller is powered with no fault, 
the contact is open.

Min.: 10 mA, 24 Vdc
Max. inductive load: 1.5 A for 250 Vac and 30 Vdc
Max. resistive load: 5 A for 250 Vac or 30 Vdc
