High Voltage Warning

WARNING

The voltage of the adjustable frequency drive is dangerous whenever it is connected to line power. Incorrect installation of the motor or adjustable frequency drive could result indeath, serious injury or damage to the equipment. Consequently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.

Safety Note

WARNING

The voltage of the adjustable frequency drive is dangerous whenever connected to line power. Incorrect installation of the motor, adjustable frequency drive or serial communication bus could result in death, serious personal injury or damage to the equipment. Consequently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied with.

WARNING

Failure to follow instructions below could result in death or serious injury.

Safety Regulations

1. The adjustable frequency drive must be disconnected from line power if repair work is to be carried out. Make sure that the line power supply has been disconnected and that the necessary time has passed before removing motor and line power plugs.

2. The [STOP/RESET] key on the keypad of the adjustable frequency drive does not disconnect the equipment from line power and is thus not to be used as a safety switch.

3. Correct protective grounding of the equipment must be established, the user must be protected against supply voltage, and the motor must be protected against overload in accordance with applicable national and local regulations.

4. The ground leakage currents are higher than 3.5 mA.

5. Protection against motor overload is set by par.1-90 set par.1-90 Note: The function is initialized at 1.16 x rated motor current and rated motor frequency. For the North American market: The ETR functions provide class 20 motor overload protection in accordance with NEC.

6. Do not remove the plugs for the motor and line power supply while the adjustable frequency drive is connected to line power. Make sure that the line power supply has been disconnected and that the necessary time has passed before removing motor and line power plugs.

7. Please note that the adjustable frequency drive has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and external 24 Vdc have been installed. Make sure that all voltage inputs have been disconnected and that the necessary time has passed before commencing repair work.

Safety

Installation at high altitudes

WARNING

Installation at high altitude: 380–500 V, enclosure A, B and C: At altitudes above 6,561 ft [2 km], please contact Trane regarding PELV/Class II. 380–500 V, enclosure D, E and F: At altitudes above 9,842 ft [3 km], please contact Trane regarding PELV/Class II. If the drive is to be installed over 6,561 ft [2 km] altitude, then the PELV specifications are not fulfilled anymore, i.e., the distances between components and critical parts become too small. To maintain the clearance for functional insulation anyway, the risk for overvoltage must be reduced by means of external protective devices or some kind of galvanic isolation. De-rating should also be taken into consideration, since cooling the drive is more difficult at high altitude. Please contact Trane in such cases. Failure to follow recommendations could result in death or serious injury.

WARNING

Warning against Unintended Start

While parameters are being changed, the motor may start. Consequently, the stop key [STOP/RESET] must always be activated, following which data can be modified.

A motor that has been stopped may start if faults occur in the electronics of the adjustable frequency drive, or if a temporary overload or a fault in the supply line power or the motor connection ceases.

Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. Failure to follow recommendations could result in death or serious injury.

WARNING

Touching the electrical parts could result in death or serious injury - even after the equipment has been disconnected from line power.

Also make sure that other voltage inputs have been disconnected, such as external 24 VDC, load sharing (linkage of DC intermediate circuit), as well as the motor connection for kinetic backup. Refer to the Instruction Manual for further safety guidelines. Failure to follow recommendations could result in death or serious injury.

WARNING

The adjustable frequency drive DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard, disconnect the adjustable frequency drive from line power before carrying out maintenance. Wait at least as follows before doing service on the adjustable frequency drive: Failure to follow recommendations could result in death or serious injury.

Protection against motor overload is not included in the factory setting. If this function is desired, set par. 1-90

Motor Thermal Protection to data value ETR trip 1 [4] or data value ETR warning 1 [3].

Do not remove the plugs for the motor and line power supply while the adjustable frequency drive is connected to line power. Make sure that the line power supply has been disconnected and that the necessary time has elapsed before removing motor and line power plugs.

Please note that the adjustable frequency drive has more voltage sources than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) or external 24 V DC are installed. Make sure that all voltage sources have been disconnected and that the necessary time has elapsed before commencing repair work.

Failure to follow recommendations could result in death or serious injury.

WARNING

Warning against unintended start

The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the adjustable frequency drive is connected to line power. If personal safety considerations (e.g., risk of personal injury caused by contact with moving machine parts following an unintentional start) make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient. In such cases, the line power supply must be disconnected or the

The motor may start while setting the parameters. If this means that personal safety may be compromised (e.g., personal injury caused by contact with moving machine parts), motor starting must be prevented, for instance by use of the

A motor that has been stopped with the line power supply connected, may start if faults occur in the electronics of the adjustable frequency drive, through temporary overload or if a fault in the power supply grid or motor connection is remedied. If unintended start must be prevented for personal safety reasons (e.g., risk of injury caused by contact with moving machine parts), the normal stop functions of the adjustable frequency drive are not sufficient. In such cases, the line power supply must be disconnected or the

Safety

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to follow recommendations could result in death or serious injury.

1. Control signals from, or internally within, the adjustable frequency drive may in rare cases be activated in error, be delayed or fail to occur entirely. When used in situations where safety is critical, e.g., when controlling the electromagnetic brake function of a hoist application, these control signals must not be relied on exclusively.

Note When using the

Safe Stop

function, always follow the instructions in the

Safe Stop

section of the Design Guide.

WARNING

Disconnect all electric power, including remote disconnects. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Use an appropriate voltmeter to verify that the unit is discharged. Failure to disconnect power and ensure unit is discharged before servicing could result in death or serious injury. Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing (linkage of DC intermediate circuit), as well as the motor connection for kinetic backup. Systems where adjustable frequency drives are installed must, if necessary, be equipped with additional monitoring and protective devices according to the valid safety regulations, e.g., law on mechanical tools, regulations for the prevention of accidents, etc. Modifications on the adjustable frequency drives by means of the operating software are allowed. Failure to follow recommendations could result in death or serious injury.

Hoisting applications: The adjustable frequency drive functions for controlling mechanical brakes cannot be considered as a primary safety circuit. There must always be a redundancy for controlling external brakes.

Protection Mode

Once a hardware limit on motor current or DC link voltage is exceeded, the drive will enter “Protection mode”. “Protection mode” means a change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues 10 sec after the last fault and increases the reliability and the robustness of the drive while re-establishing full control of the motor. In hoist applications, “Protection mode” is not usable because the drive will usually not be able to leave this mode again, and therefore it will extend the time before activating the brake – which is not recommended. "Protection mode” can be disabled by setting par.14-26 the drive will trip immediately if one of the hardware limits is exceeded.

Note It is recommended to disable protection mode in hoisting applications (par.14-26

0).

Special Conditions

Electrical ratings:

The rating indicated on the nameplate of the adjustable frequency drive is based on a typical 3-phase line power supply within the specified voltage, current and temperature ranges, which are expected to be used in most applications.

The adjustable frequency drives also support other special applications, which affect the electrical ratings of the adjustable frequency drive. Special conditions that affect the electrical ratings might be:

• Single phase applications.

• High temperature applications that require derating of the electrical ratings.

• Marine applications with more severe environmental conditions.

Other applications might also affect the electrical ratings.

Consult the relevant sections in this manual and in the for information about the electrical ratings.

Installation requirements:

The overall electrical safety of the adjustable frequency drive requires special installation considerations regarding:

• Fuses and circuit breakers for overcurrent and short-circuit protection

• Selection of power cables (line power, motor, brake, load sharing and relay)

• Grid configuration (grounded delta transformer leg, IT,TN, etc.)

• Safety of low-voltage ports (PELV conditions).

Consult the relevant clauses in these instructions and in the for information about the installation requirements.

Technical Overview

BACnet (Building Automation and Control Network) is an open data communications protocol, American National Standard (ANSI/ASHRAE 135-1995). BACnet provides a means by which computer-based control equipment from different manufacturers can work together. BACnet is designed to handle many types of building controls, including HVAC, lighting, security, fire, access control, maintenance and waste management. BACnet permits flexibility for expansion and different equipment combinations.

Conformance Classes, Function Groups and the PICS: Evaluating the capabilities of a BACnet device is potentially a formidable task, given the great choice of objects, properties and services, which can be implemented, as well as the fact that it is not necessary for every BACnet device to have a full BACnet implementation in order to carry out its task. ASHRAE's BACnet Committee recognized this problem and responded with aids to evaluation in the form of "Conformance Classes", "Function Groups" and the "Protocol Implementation Conformance Statement" (PICS).

The BACnet protocol defines six levels of conformance classes, each of which specifies the minimum subset of services implemented on the device. The lowest level, Conformance Class 1, requires only that the BACnet device contain a device object and that it be able to execute (respond to) a ReadProperty service request. Each successive conformance class level adds service requests that must be executable by the device, as well as the service requests it must be able to initiate. Conformance Class 6 requires 21 types of service requests (of the 32 overall) to be implemented, of which 20 must be initiable and 17 executable. Conformance class thus provides a measure of the device's ability to communicate.

Function groups specify a combination of objects and services necessary to carry out certain building automation functions. They are specified independently of conformance class, though the implementation of some of the function groups automatically confers some conformance class higher than 1.

How to Install

Instructions:

- Remove the keypad panel from the adjustable frequency drive.

- Remove the frame located beneath and discard.

- Push the option into place. Two positions are possible, with cable terminal facing either up or down. The cable up position is often most suitable when several adjustable frequency drives are installed side by side in a rack, as this position permits shorter cable lengths.

- Push the serial communication bus option adaptor frame for the adjustable frequency drive into place.

- Remove the plug for the Drive port and connect the plug that is connected to the BACnet option

- Replace the keypad panel.

- Attach cable.

- Fasten the cable in place using cable holders. The adjustable frequency drive top surface has pre-drilled threaded holes for attaching the cable holders to the unit.

Cabling

Cable lengths and number of nodes

The maximum cable length allowable in one segment is dependent on the transmission speed. The total cable length includes drop cables if any. A drop cable is the connection from the main bus cable to each node. If a Tconnection is used, permissible cable length and maximum number of nodes/drives are 1, 2, 3 and 4 bus segments.

Drop cable connection (i.e., T-connection) beyond the cable lengths indicated is not recommended, due to the increased risk of reflection occurring. Instead, Trane recommends direct connection of the adjustable frequency drive.

Note that a repeater is a node in both of the two segments it connects. The number of adjustable frequency drives is based on a single master system. If there are two or more masters (e.g., PC tools, routers), the number of adjustable frequency drives must be reduced correspondingly.
