3.5 Wiring Practices
3.5.1 Applicable Codes
Pay conscientious attention to ensuring that the installation wiring is installed at least in con-
formity with the NEC standards. Where local codes exceed these requirements, they must
be followed.
All models are listed by the Underwriters Laboratories, Inc. (UL) and are certified by the Ca-
nadian Underwriters Laboratories (cUL) and therefore conform to the requirements of NEC
and CEC. Installations that are to meet the requirements of UL and cUL must be realised
in conformity with the UL and cUL specifications. Refer to the corresponding electrical data
on the rating plates of the ACP 3000 unit and the motor.
3.5.2 Power Wiring
Power wiring are those wires which are connected during installation to the power circuit
terminals, L1, N, L2, L3, M1, M2, and M3. Power wiring must be selected as follows:
1. Use only VDE, UL or cUL recognized wire.
2. Wire voltage rating must be a minimum of 300 V for 230 VAC systems, and 600 V for
400 VAC systems.
3. The core cross section and the associated fuse are given in the tables in chapter 3.6.2,
page 22. The wires must consist of copper and be designed for insulation temperatures
of 60 °C or 75 °C.
4. Grounding must be in accordance with VDE, NEC and CEC.
NOTES:
Never connect input AC power to the motor output terminals M1, M2 and M3 or dam-
age to the drive will result.
The output voltage of variable-frequency controllers contains high-frequency components
that might cause disturbances in other installations. Therefore, avoid laying control cables
and mains input cables in the same cable duct or conduit together with the output cables
from the converter to the motor (see also chapter 3.3.4, “Interference Suppression Meas-
ures”).
3.5.3 Control Wiring/Interface
All interfaces or control inputs and outputs possess only basic insulation by the
mains and must be incorporated in a further protective measure.
Use a dummy plug as additional protection if interface J22 is not allocated.
This is wiring connected to the control terminal strip (20 terminals). It must be selected as
follows:
1. Shielded wire is recommended to prevent electrical noise interference from causing im-
proper operation or nuisance tripping. Only connect the screen on one end to the “CM”
terminal on the converter’s control terminal strip (see also chapter 3.3.4, “Interference
Suppression Measures”).
2. Use only VDE, UL or cUL recognized wire.
3. Wire voltage rating must be a minimum of 300 V for 230 VAC systems, and 600 V for
400 VAC systems. This is Class 1 wire.
4. Never run the control wiring in the same conduit or raceway with power wiring.
