Installation and Use

The information given in this publication is derived from tests and
calculations on sample products. It is provided to assist in the correct
application of the product, and is believed to correctly reflect the
behaviour of the product when operated in accordance with the
instructions. The provision of this data does not form part of any contract
or undertaking. Where a statement of conformity is made with a specific
standard, the manufacturer takes all reasonable measures to ensure
that its products are in conformance. Where specific values are given
these are subject to normal engineering variations between samples of
the same product. They may also be affected by the operating
environment and details of the installation arrangement.
The manufacturer accepts no liability for any consequences resulting
from inappropriate, negligent or incorrect installation of the equipment.
WARNING - This warning applies to products intended to
be used with variable speed drives.
The adjustable speed drive uses high voltages and currents,
carries a high level of stored electrical energy, and is used to
WARNING
control mechanical plant which can cause injury.
Close attention is required to the electrical installation and
the system design to avoid hazards either in normal
operation or in the event of equipment malfunction.
System design, installation, commissioning and
maintenance must be carried out by personnel who have the
necessary training and experience. They must read this
safety information and the instruction manual carefully.
Failure to observe the following instructions can cause
physical injury or death, or damage to the equipment.
1.3

Enclosure

Unless stated otherwise in the installation instructions, the product is
intended to be mounted in an enclosure which prevents access except
by trained and authorized personnel, and which prevents the ingress of
contamination. It is designed for use in an environment classified as
pollution degree 2 in accordance with IEC 60664-1. This means that only
dry, non-conducting contamination is acceptable.
1.4

Competence of the installer

Installation should be carried out by professional installers who are
familiar with the requirements for safety and EMC. The installer 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.

Electric Shock and Fire Hazards

WARNING - Dangerous voltage
Where products are supplied by or connected to mains
voltages, the voltages used can cause severe electrical
shock and/or burns, and could be lethal. Extreme care is
WARNING
necessary at all times when working with or adjacent to the
equipment. Refer to the relevant documentation.
1.5.1 AC supply
The AC supply must be isolated before any servicing work is performed,
other than adjustments to the settings or parameters specified in the
manual.
1.5.2 Live terminals
Some types of signal and control lines carry hazardous voltages (120/
240 V) and can cause severe electric shock and may be lethal.
1.5.3 Stored charge
Some products contain capacitors that remain charged to a potentially
lethal voltage after the power supply has been disconnected. It is
recommended that the power supply is isolated at least ten minutes
before working on the equipment.
1.6

Electrical installation

1.6.1 Protective Ground (Earth) connection
The ground loop impedance must conform to the requirements of local
safety regulations. The equipment must be grounded by a connection
capable of carrying the prospective fault current until the protective
device (fuse or circuit breaker) disconnects the supply. The ground
connections must be inspected and tested at appropriate intervals.
1.6.2 Fuses
The supply to the equipment must be installed with suitable protection
against overload and short-circuits. The tables in the relevant
documentation show recommended fuse ratings. Failure to observe
these installation instructions could result in fire.
1.6.3 Cables
The cable sizes in the relevant documentation are only a guide. The
mounting and grouping of cables affects their current-carrying capacity,
in some cases smaller cables may be acceptable but in other cases a
larger cable is required to avoid excessive temperature or voltage drop.
Refer to local wiring regulations for the correct size of cables. Failure to
observe these installation instructions could result in fire.
1.6.4 Terminal connections and torque settings
Loose power connections can be a fire risk. Always ensure that
terminals are tightened to the specified torques. Refer to the tables in the
relevant documentation.
1.6.5 High voltage insulation (flash) testing
High voltage insulation (flash) testing should not be carried out on the
equipment.
1.6.6 ELV terminals
The ELV terminals are insulated from the mains supply by a single
isolation barrier.
These terminals must be prevented from human contact by an additional
isolation barrier, for example a terminal cover.
1.6.7 SELV terminals
SELV terminals can be safely connected to other SELV equipment and
further protection against human contact is not required.
If an ELV terminal is connected directly to a SELV circuit (on the drive or
other equipment), the combined circuit is ELV.
For this reason, ELV terminals should not be connected to SELV circuits
unless it is acceptable to compromise the SELV circuit.
