Input Connections for 3.3 kW and 5 kW units
The AC input connector is located on the rear panel. It is a 3-terminal
wire clamp for 3.3 kW single-phase units, or a 4-terminal wire clamp
for 3.3 kW and 5 kW 3-phase units. Input voltage and current ratings
are as follows:
Unit
Nominal AC
Input
Input Current @
100% load
Frequency
3.3 kW single-phase 190 – 240 VAC
23 – 24 A max.
50/60 Hz
3.3 kW 3-phase
190 – 240 VAC
13.6 – 14.5 A max.
50/60 Hz
380 – 415 VAC
6.8 – 7.2 A max.
50/60 Hz
5 kW 3- phase
190 – 240 VAC
21 – 22 A max.
50/60 Hz
380 – 415 VAC
10.5 – 12 A max.
50/60 Hz
NOTE
The AC input line voltage rating is permanently built into the unit and cannot
subsequently be changed.
Connect the cable to the AC input connector as follows:
1
Strip the outside insulation of the AC cable approximately 10 cm
(4 in). Trim the wires so that the green/yellow ground wire is 10
mm (0.4 in) longer than the other wires. Strip 10 mm (0.4 in) at
the end of each of the wires.
2
Unscrew the base of the strain relief from the wire compression
nut. Place the locknut inside the AC input cover with the flat side
of the nut against the cover. Insert the base through the outside
opening of the AC input cover. Screw the base securely onto the
locknut from the outside. Tighteming torque: 17 ft-lb (23 Nm).
3
Slide the wire compression nut over the AC cable. Insert the
stripped wires through the strain relief base until the outer cable
jacket is flush with the inside edge of the base. Place a wrench on
the base to keep it from turning. Now tighten the compression
nut to the base while holding the cable in place. Tightening
torque: 14 – 16.2 ft-lb (19 – 22 Nm). Refer to the following figure.
3-phase cable (shown)
has four conductors.
Single-phase cable has
three conductors.
