Chapter 3 – Electrical Installation
ACS/ACC/ACP 604/607 Frequency Converters 3-7
WARNING! This work should only be carried out by a qualified
electrician. The
Safety Instructions on the first pages of this manual
must be followed. Negligence of these instructions can cause injury or
death.
ACx 607 The mains and motor cables connect to the ACx 607 in the left part of
the cabinet. Mains, motor and control cable lead-through is from below
or from above. To locate the terminals see the dimensional drawings
(
Appendix B). To connect the mains and motor cables to the ACx 607,
carry out the following procedure.
1. Make sure that the ACx 607 is disconnected from the mains
network during installation. Wait for 5 minutes if the ACx 607
is already connected to the mains after disconnecting mains
power.
2. Open the cabinet door.
3. Open the hinged assembly plate to gain access to the mains and
motor cable terminals.
4. Measure the voltage between each input terminal (U1, V1, W1)
and earth with a multimeter (impedance at least 1 M
Ω
) to
ensure that the frequency converter is discharged.
5. Lead the cables inside the cabinet through the EMC sleeves.
If cable entry is not possible otherwise, remove the lead-through plate and slide it
onto the cable. After the earthing connections are done, fasten the lead-through
plate. IP 54 and cable entry from above: Remove the rubber grommets from the
lead-through plates and cut them to adequate diameter for the mains and the
motor cable. To ensure proper sealing, cut along the diameter marking that
corresponds to the cable diameter. Slide the grommet onto the cable.
Earthing Connections
6. Strip the cable according to figure below. (For IP 54 units, add a
rubber grommet on the cable under the lead-through plate.)
7. Tighten the EMC sleeve on the bare cable screen with cable ties.
8. Twist the screen wires together to a pigtail and connect to the PE
terminal of the cabinet.
