e. A series of DIN rail mount terminal blocks are pro-
vided for field wiring. See Figure 2 for the wiring diagram. These
terminals are rated as follows:
(1). Relay Output: 18-12 AWG (0.75 – 4 mm2), tightening torque
3.4 in-lb (0.4 N
•
m), 240VAC, 3.0A max.
(2). Aux. Power: 18-12 AWG (0.75 – 4mm2), 240VAC, 20A max.
(3). Audio/ISDN: 26-12 AWG (0.25 – 4mm2), Cu conductors only
f. Upon completion of field wiring, re-fit the cover.
Secure the M8 screws to ensure weather/dust tightness and hazardous
location ratings.
