Disposal and Recycling (WEEE)
REACH legislation
EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH)
requires the supplier of an article to inform the recipient if it contains more than a specified proportion of any
substance which is considered by the European Chemicals Agency (ECHA) to be a Substance of Very High
Concern (SVHC) and is therefore listed by them as a candidate for compulsory authorisation.

When electronic products reach the end of their useful life, they must not be disposed of along
with domestic waste but should be recycled by a specialist recycler of electronic equipment.
Control Techniques products are designed to be easily dismantled into their major component
parts for efficient recycling. The majority of materials used in the product are suitable for
recycling.
Product packaging is of good quality and can be re-used. Large products are packed in wooden
crates. Smaller products are packaged in strong cardboard cartons which have a high recycled
fibre content. Cartons can be re-used and recycled. Polythene, used in protective film and bags
for wrapping the product, can be recycled. When preparing to recycle or dispose of any product
or packaging, please observe local legislation and best practice.

These electronic drive products are intended to be used with appropriate motors, controllers,
electrical protection components and other equipment to form complete end products or
systems. Compliance with safety and EMC regulations depends upon installing and
configuring drives correctly, including using the specified input filters.
The drives must be installed only by professional installers who are familiar with
requirements for safety and EMC. Refer to the Product Documentation. An EMC data sheet is
available giving detailed information. The assembler is responsible for ensuring that the end
product or system complies with all the relevant laws in the country where it is to be used.

IMPORTANT NOTICE
These electronic drive products are intended to be used with appropriate motors, controllers,
electrical protection components and other equipment to form complete end products or
systems. It is the responsibility of the installer to ensure that the design of the complete
machine, including its safety-related control system, is carried out in accordance with the
requirements of the Machinery Directive and any other relevant legislation. The use of a
safety-related drive in itself does not ensure the safety of the machine. Compliance with
safety and EMC regulations depends upon installing and configuring drives correctly,
including using the specified input filters. The drive must be installed only by professional
installers who are familiar with requirements for safety and EMC. The assembler is
responsible for ensuring that the end product or system complies with all relevant laws in the
country where it is to be used. For more information regarding Safe Torque Off, refer to the

* A minimum clearance of 50 mm (1.97 in) above and below Frame 01 to 04 products is
permissible in applications where either the ambient operating temperature is 35 °C
(95 °F) or less or the average output current is derated by 20 %.
Derating for reduced clearances is to be applied in addition to the derating for increased
switching frequency if operating above 3 kHz. Refer to the Power Installation Guide for the
current derating due to an increase in switching frequency.
If Din rail mounting is used in an installation, then mounting screws should be used to
secure the drive to the back plate.

4 Electrical installation
An overlay of the electrical connections / terminals is included on the back page of this manual.
4.1 AC supply requirements
Voltage:
100 V drive: 100 V to 120 V ±10 %
200 V drive: 200 V to 240 V ±10 %
400 V drive: 380 V to 480 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance
between phases).
Frequency range: 45 to 66 Hz
For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA.
4.2 External braking resistor
4.2.1 Minimum resistance values and peak power rating for the braking resistor
at 40 °C (104 °F)
Table 4-1 Braking resistor resistance and power rating (100 V)
* Resistor tolerance: ±10 %
On the size 2 110 V drives or when connecting single phase to a dual rated 200 V unit, the
supply should be connected to L1 and L3. Also the DC bus (-) terminal on 110 V drives
has no internal connection. The 110 V drives use a voltage doubler circuit on the input,
therefore the default for Motor Rated Voltage (00.008) is 230 V.
Overload protection
When an external braking resistor is used, it is essential that an overload protection device
is incorporated in the braking resistor circuit; as shown in the electrical diagram on the
back cover.

The above leakage currents are just the leakage currents of the drive and do not take into
account any leakage currents of the motor or motor cable.
When the internal filter is installed the leakage current is high. In this case a permanent
fixed ground connection must be provided, or other suitable measures taken to prevent a
safety hazard occurring if the connection is lost.
When the leakage current exceeds 3.5 mA, a permanent fixed ground connection must be
provided using two independent conductors each with a cross-section equal to or
exceeding that of the supply conductors. The drive is provided with two ground
connections to facilitate this. Both ground connections are necessary to meet EN 61800-
5-1: 2007.

4.3.1 Use of residual current device (RCD)
There are three common types of ELCB / RCD:
1. AC - detects AC fault currents
2. A - detects AC and pulsating DC fault currents (provided the DC current reaches zero at least
once every half cycle)
3. B - detects AC, pulsating DC and smooth DC fault currents
• Type AC should never be used with drives.
• Type A can only be used with single phase drives
• Type B must be used with three phase drives
If an external EMC filter is used with an ELCB / RCD, a delay of at least 50 ms should be
incorporated to ensure spurious trips are not seen. The leakage current is likely to exceed the trip
level if all of the phases are not energized simultaneously.
4.4 Control terminal configurations and wiring
The setting of Pr 00.005 automatically sets the drive configuration
Action will only occur if the drive is inactive and no User Actions are running. Otherwise, the
parameter will return to its pre altered value on exit from edit mode. All parameters are saved if this
parameter changes.
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.
