1.9.2 Electric connection
To the terminal board (X, X1):
- 3 terminals (PE, N, L) on the sourcing board with cross-section of connection wire 0,05 - 1,5
mm
2
for solid wire and for flexible wire. Max. terminal screw tightening torque 0,5 N.m
- 5 terminals (READY, R1, R2) with cross-section of connection wire 0,05 – 1,5 mm
2
for solid
wire and for flexible wire. Max. terminal screw tightening torque 0,5 N.m
- 10 terminals (COM, CLOSE, OPEN, I1, I2, +IN, -IN, SH, +L, -L) with cross-section of connection
wire 0,05 – 1 mm
2
for solid wire and for flexible wire. Max. terminal screw tightening torque
0,19 N.m.
Attention: Thermic resistance incoming wires must be minimum +80°C

Cable glands :
- 3 cable glands - cable diameter from 6 to 10,5 mm.
Protection terminals:
During start-up - during installation of device:
- outside and inside ground terminal must be connected for safe operation of the actuator. The position
of the outside and inside ground terminal can be seen in Fig. 1a and Fig. 1b. For forcing - in wires in
external ground terminal be needed use pliers HP3 for insulated eyelet (firm CEMBRE).
- a switch / circuit breaker must be installed on the power supply line, as close as possible to the
device, easily accessible to operators and identified as the actuator isolation switch.
Outside and inside, are together connected and marked with the mark of protection grounding.
The electric connection should be made according to wiring diagrams pasted into the upper cover of the
EA.
Fuses:
Actuator power supply board is installed with power supply fuse (F3). Location of the fuse on the
power supply board can be seen in Fig.1a.
Fuse values and parameters: - for voltage 24 V AC T 1,6 A /250V
- for voltage 110-120 V AC T 0,315 A /250V
- for voltage 220-240 V AC T 0,160 A /250V
Warning: Minimum thermal resistance of power supply cables and wires must be +80°C.
