2Safety

2.1.1 Safety note

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 may cause damage to the equipment, serious personal injury or death. Con-

sequently, the instructions in this manual, as well as national and local rules and safety regulations, must be followed.

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 plugs.

2. The [STOP/RESET] key on the control panel 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

Motor Thermal Protection

. If this function is desired, set par. 1-90 to data value [ETR trip]

(default value) or data value [ETR warning]. 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 plugs.

7. Please note that the adjustable frequency drive has more voltage inputs than L1, L2 and L3 when load sharing (linking of the DC intermediate

circuit) and external 24 V DC have been installed. Make sure that all voltage inputs have been disconnected and that the necessary time has

passed before commencing repair work.

Installation at High Altitudes

At altitudes higher than 6,600 feet [2 km], please contact Danfoss regarding PELV.

Warning against Unintended Start

1. 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 make it necessary to ensure that no unintended start occurs, these stop functions are not

sufficient. 2. 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. 3. 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 or the motor connection ceases.

Warning:

Touching the electrical parts may be fatal - even after the equipment has been disconnected from line power.

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.

200–240 V, [0.25–3.7 kW]: wait at least 4 minutes.

200–240 V, 7.5–60 hp [5.5–45 kW]: wait at least 15 minutes.

380–480 V, 5–10 hp [0.37–7.5 kW]: wait at least 4 minutes.

380–480 V, 15–125 hp [11–90 kW]: wait at least 15 minutes.

525–600 V, 1.5–10 hp [1.1–7.5 kW]: wait at least 4 minutes.

525–600 V, 150–350 hp [110–250 kW]: wait at least 20 minutes.

525–600 V, 175–750 hp [315–560 kW], wait at least 30 minutes.

A shorter time is allowed only if indicated on the nameplate for the specific unit.

Leakage Current

The ground leakage current from the VLT AQUA Drive FC 200 exceeds 3.5 mA. According to IEC 61800-5-1, a reinforced protective

ground connection must be ensured by means of: a min. 0.016 in² [10 mm²] Cu or 0.025 in² [16 mm²] Al PE-wire, or an additional

PE wire - with the same cable cross-section as the line power wiring - must be terminated separately.

Residual Current Device

This product can cause 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 RCD Application Note MN.90.GX.02.

Protective grounding of the VLT AQUA Drive FC 200 and the use of RCDs must always follow national and local regulations.

2.1.3 Before Commencing Repair Work

1. Disconnect the adjustable frequency drive from line power.

2. Disconnect DC bus terminals 88 and 89.

3. Wait at least the time mentioned above in the section General Warning.

4. Remove motor cable

2.1.4 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 which require derating of the electrical ratings

• Marine applications with more severe environmental conditions.

Consult the relevant clauses in these instructions and in the VLT®AQUA Drive Design Guide for information about the electrical ratings.
