1.1 Safety

1.1.1 Warnings

WARNING

HIGH-VOLTAGE WARNING

The voltage of the frequency converter is dangerous

whenever it is connected to mains. Incorrect installation

of the compressor or frequency converter may cause

death, serious injury, or equipment damage. To avoid

death, serious injury, or equipment damage:

•Comply with the instruction in this manual as

well as local and national rules and safety

regulations.

WARNING

DISCHARGE TIME!

Frequency converters contain DC-link capacitors that can

remain charged even when the frequency converter is

not powered. To avoid electrical hazards, disconnect AC

mains, any permanent magnet type compressors, and

any remote DC-link power supplies, including battery

back-ups, UPS, and DC-link connections to other

frequency converters. Wait for the capacitors to fully

discharge before performing any service or repair work.

The waiting time is listed in Table 1.1. Failure to wait the

specied time after power has been removed before

doing service or repair could result in death or serious

injury.

Voltage [V] Cooling capacity [TR] Minimum waiting time

(minutes)

3x400 4–5 4

3x400 6.5 15

Table 1.1 Discharge Time

CAUTION

Leakage Current

The ground leakage current from the frequency

converter exceeds 3.5 mA. According to IEC 61800-5-1 a

reinforced protective earth connection must be ensured

with a minimum 10 mm2Cu or an extra PE wire with the

same cable cross-section as the mains wiring. Terminate

the PE connection separately.

Residual Current Device

This product can cause a DC current in the protective

conductor. Where a residual current device (RCD) is used

for extra protection, only an RCD of Type B (time

delayed) shall be used on the supply side of this

product. See also Danfoss Application Note on RCD.

Protective earthing of the frequency converter and the

use of RCDs must always follow national and local

regulations.

NOTICE

INSTALLATION AT HIGH ALTITUDES

For altitudes above 2000 m, contact Danfoss regarding

PELV.

1.1.2 Safety Instructions

•Make sure that the frequency converter is

properly connected to ground.

•Do not remove mains connections, compressor

connections, or other power connections while

the frequency converter is connected to power.

•Protect users against supply voltage.

•Protect the compressor against overloading

according to national and local regulations.

•The ground leakage current exceeds 3.5 mA.

•The [O/Reset] key is not a safety switch. It does

not disconnect the frequency converter from

mains.

1.2 Introduction

CAUTION

If reinserted, only use M3x12 screw.

1.2.4 Avoid Unintended Start

While the frequency converter is connected to mains, the

compressor can be started/stopped using digital

commands, bus commands, references or via the LCP.

•Disconnect the frequency converter from mains

whenever personal safety considerations make it

necessary to avoid unintended start of any

compressors.

•To avoid unintended start, always press [O/

Reset] before changing parameters.

Equipment containing electrical components

must not be disposed of together with domestic

waste.

It must be separately collected with electrical

and electronic waste according to local and

currently valid legislation.

1.3 Installation

1.3.1 Before Starting Repair Work

1. Disconnect from mains (and external DC supply, if

present).

2. Wait as stated in Table 1.1 for discharge of the

1.3.5 Connecting to Mains and Compressor

The frequency converter is designed to operate Danfoss

VZH Compressors. For maximum cross-section on wires, see

chapter 1.7 General Specications.

•To comply with EMC emission specications, use

a shielded/armored compressor cable and

connect this cable to both the decoupling plate

and the compressor metal.

•Keep compressor cable as short as possible to

reduce the noise level and leakage currents.

•For further details on mounting of the decoupling

plate, see VLT

Compressor Drive CDS 803

Decoupling Plate Installation Instructions.

•Also see EMC-Correct Installation in the VLT

Compressor Drive CDS 803 Design Guide.

1. Mount the ground wires to ground terminal.

2. Connect compressor to terminals U, V, and W, see

Table 1.8.

1.3.6 Fuses

Branch circuit protection

To protect the installation against electrical and re hazard, all branch circuits in an installation, switch gear, machines, and

so on, must be short circuit and overcurrent protected according to national and local regulations.

Short-circuit protection

Danfoss recommends using the fuses listed in Table 1.9 to protect service personnel or equipment if there is an internal

failure in the unit or a short circuit on the DC-link. The frequency converter provides full short-circuit protection if there is a

short circuit on the compressor.

Overcurrent protection

To avoid overheating of the cables in the installation, provide overload protection. Overcurrent protection must always be

carried out according to local and national regulations. Design circuit breakers and fuses for protection in a circuit capable

of supplying a maximum of 100000 Arms (symmetrical), 480 V maximum.

UL/Non UL compliance

To ensure compliance with UL or IEC 61800-5-1, use the fuses listed in Table 1.9.

NOTICE

In the event of malfunction, failure to follow the protection recommendation may result in damage to the frequency

converter.

1.3.7 EMC-Correct Electrical Installation

General points to be observed to ensure EMC-correct electrical installation.

•Use only screened/armoured motor cables and screened/armoured control cables.

•Connect the screen to ground at both ends.

•Avoid installation with twisted screen ends (pigtails), since this ruins the screening eect at high frequencies. Use

the cable clamps provided instead.

•Ensure the same potential between frequency converter and ground potential of the PLC.

•Use star washers and galvanically conductive installation plates.
