The issues discussed are essential for safe and trouble-free use of the drive system. Note: Please note that the installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations.
Free space requirements The modules can be installed side by side. The dimensions of the drive modules are presented in chapter Dimension drawings. The free space requirements (valid for both frame sizes) are shown below. Free space above the module: 200 mm (7.9”) Free space in front of the module: 50 mm (2.0”)
Cooling and degrees of protection The cabinet must have enough free space for the components to ensure sufficient cooling. Observe the minimum clearances given for each component. The air inlets and outlets must be equipped with gratings that • guide the air flow •...
Preventing the recirculation of hot air Typical vertical mounting Cabinet (side view) AREA Main airflow out Air baffle plates COOL AREA Main airflow in Outside the cabinet Prevent hot air circulation outside the cabinet by leading the outcoming hot air away from the area where the inlet air to the cabinet is taken.
Cabinet heaters Use a cabinet heater if there is a risk of condensation in the cabinet. Although the primary function of the heater is to keep the air dry, it may also be required for heating at low temperatures. When placing the heater, follow the instructions provided by its manufacturer.

The box contains: • drive module, with factory-installed options • one cable clamp plate for control cabling with screws • screw-type terminal blocks to be attached to the headers on the JCU Control Unit •...
Before installation Check the installation site according to the requirements below. Refer to Dimension drawings for frame details. Requirements for the installation site Technical data for the allowed operation conditions of the drive. The drive is to be mounted in an upright position. The wall the drive is to be mounted on must be as even as possible, of non-flammable material and strong enough to carry the weight of the drive.
WARNING! As the leakage current of the device typically exceeds 3.5 mA, a fixed installation is required according to IEC 61800-5-1. Supply disconnecting device Install a hand-operated input disconnecting device (disconnecting means) between the AC power source and the drive. The disconnecting device must be of a type that can be locked to the open position for installation and maintenance work.
The protective characteristics of circuit breakers depend on the supply voltage as well as the type and construction of the breakers. There are also limitations pertaining to the short-circuit capacity of the supply network. Your local ABB representative can help you in selecting the breaker type when the supply network characteristics are known.
Safe Torque Off The drive supports the Safe Torque Off function according to standards prEN 61800-5-2; EN 954-1 (1997); IEC/EN 60204-1: 1997; EN 61508: 2002 and EN 1037: 1996. The Safe Torque Off function disables the control voltage of the power semiconductors of the drive output stage, thus preventing the inverter from generating the voltage required to rotate the motor (see diagram below).
Selecting the power cables General rules Dimension the supply (input power) and motor cables according to local regulations. • The cable must be able to carry the drive load current. See the chapter Technical data for the rated currents. ° •...
Alternative power cable types Power cable types that can be used with the drive are represented below. Motor cable (also recommended for supply cabling) Symmetrical shielded cable: three phase conductors and Note: A separate PE conductor is required if the a concentric or otherwise symmetrically constructed PE conductivity of the cable shield is not sufficient for the conductor, and a shield...
Protecting the relay output contacts and attenuating disturbances in case of inductive loads Inductive loads (relays, contactors, motors) cause voltage transients when switched off. The relay output on the drive is protected with varistors (250 V) against overvoltage peaks. In addition, it is highly recommended to equip inductive loads with noise attenuating circuits (varistors, RC filters [AC] or diodes [DC]) in order to minimize the electromagnetic emissions at switch-off.
Control panel cable The cable connecting the control panel to the drive must not exceed 3 metres in length. The cable type tested and approved by ABB is used in control panel option kits. Connection of a motor temperature sensor to the drive I/O See page 67.

Ignoring the safety instructions can cause injury or death.
Protective Earth conductor using a measuring voltage of 500 V DC. The insulation resistance of an ABB motor must exceed 10 Mohm (reference value at 25 °C or 77 °F). For the insulation resistance of other motors, please consult the manufacturer’s instructions.
Connection to an IT (ungrounded) power system WARNING! Before connecting the drive to an IT power system [an ungrounded power system or a high resistance-grounded (over 30 ohms) power system] or a corner-grounded power system, the internal EMC filtering of the drive must be disconnected.
