1. MOUNTING AND WIRING.

1.1 ENVIRONMENTAL CONDITIONS

1.1.1 IP00 MODEL

The maximum V2 ambient/working temperature is 40ºC. It is possible to be operated up to higher

temperature of 50ºC, by over sizing the soft starter 2% per extra degree.

Example: Motor 15kW, 380V, 30A

Working temperature 50ºC.

Soft-Starter required: At 40ºC the soft starter required should be a V2030 (30Amps), but at 50ºC the

soft starter should be oversized a 2% per extra ºC. Thus,

Temperature: 10°C; 2% x 10ºC means a 20% oversize:

I motor x 20% = 30 x 1.2 = 36 Amp

Then the soft starter required is a V2045 (@50ºC).

1.1.2 IP54 MODEL

The maximum V2 ambient/working temperature is 50ºC.

1.2 IEC PROTECTION

The V2 soft-starter ingress protection is IP00 and IP54.

1.3 MOUNTING

To improve heat dissipation, it is recommended to mount the soft starter over a metal plate.

Minimum safe 30mm side distance and 150mm top and button distance is to be kept between soft

starters.

Do not install V2 above any heat source, unless heat airflow is driven out of the cabinet.

ELECTRONIC SOFT-STARTER

1.3.1 IP00 MODEL

The V2 IP00 soft starter is designed to be mounted vertically inside an electrical cabinet with forced air-

cooling.

1.3.2 IP54 MODEL

IP54 Model can be mounted within a sealed cabinet if its internal temperature does not exceed 50ºC

and limiting the number of starts according to its technical specifications.

ESPAÑOLDEUTSCH

1.4 POWER LOSS DISSIPATION

1.4.1 IP00 MODEL

The V2 has a power loss of 3 watt per amp, this means that a V2045 has a power loss of 135 Watts at

full load.

1) Without forced cooling:

Practical example:

Ambient temperature is 30ºC.

Maximum working temperature of the V2 is 40ºC.

Power losses of the soft starter are 3 watts per amp at full load and 6 watts per amp during the start

(only with more than 6 starts per hour).

If the V2017 is going to be drawing constantly 15A, our power loss must be:

P= Im x Loss = 15 x 3 = 45 watts

This is the worst case assuming a duty cycle of 100% at full load (45W). You have also to take the

losses of switches, contactors, relays into account (20Watts).

Ploss= 45 + 20 = 65 watts

The heat transfer coefficient of metals and polyester must be known:

Polyester: 3.5 W / m²K°

Metal: 5.5 W / m²K°

The total surface required without forced cooling should be:

Area = Ploss/ k (Tr-Ta)

Area = 65 / 5.5 x (40 - 30) = 1.181m²

Chosen an 800 x 600 x 400 cabinet, the total area of dissipation is:

Area = Door + 2 (side) + Top Covers

Area = (0.8 x 0.6) + 2(0.8 x 0.4)+ (0.6 x 0.4) = 1.36m2

ENGLISH

The area of the cabinet is high enough to dissipate the total power loss.

NOTE: When you place cabinets in parallel, just take one side (for the total area) into account for thermal calculations.

2) With forced cooling:

The power loss dissipated is the same as without forced cooling, but now you have to calculate the air

flow required to get the desired differential temperature between the inside and the outside of the

cabinet.

We have a V2017 working at 30ºC ambient temperature. We want the air inside the cabinet less than

40ºC.

POWER ELECTRONICS User’s Manual V2 V2MT01II | 7

PLoss = Total power loss dissipated.

Tr = Maximum temperature inside the cabinet.

Ta = Ambient temperature.

Ø = Airflow required in m3/min.

Ø = PLoss / 20 x (Tr-Ta)

Ø = 65 / 20 x (40-30) 0.325 m3/min

NOTE: Using filters at the air intake/exhaust of the cabinet should protect the V2 from dust.

1.4.2 IP54 MODEL

IP54 range V2 do not need forced cooling as no heat is produced during nominal operation, only start

and stop heat is dissipated, thus number of starts is limited to 6 per hour and provided 50ºC as

maximum working temperature.

1.5 POWER WIRING

Most electrical wiring regulations require a mains isolator on solid-state equipment. The V2 soft-starter

falls to this category. This is to ensure there is an air break in the circuit, as semiconductors cannot be

relied upon to be safe isolation. There are many choices, the most common are using a magnethermic

protection with a trip coil, and the other is placing a contactor.

Note: Minimum recommended protection 1A for F1.

It is absolutely necessary that the installer guaranties the correct observance of the law and the regulations

that are in force in those countries or areas where this device is going to be installed.

8 | POWER ELECTRONICS User’s Manual V2 V2MT01II

ELECTRONIC SOFT-STARTER

Magnetic protection is required to protect the V2 soft-starter from damage due to a short circuit within

the V2 or on the output cabling or motor. When a faster protection was needed, it is recommended ultra

fast fuses. The fuses should be mounted as close to the V2 soft-starter as possible. Power factor

correction capacitors must not be connected after the fuses or on the output of the V2.

The V2 protects the motor with electronic overload sensing, so an external overload relay is not

necessary. If multiple motors are connected separate, overloads are required for each motor.

ESPAÑOLDEUTSCH

An isolator can be fitted after the V2 but is recommended for off load use only. A motor isolator is not

necessary for the operation of the V2 soft-starter but site standards or electrical wiring regulations may

require an isolator near the motor.

If a contactor is to be fitted, an output relay of the soft starter can energize it on receiving the start

signal.

1. 6 CONTROL WIRING

NOTE: Wiring distance.

Control wiring shouldn't run in parallel with power input or output cables to the motor. Space

at least 300mm away, and cross at right angles.

Control terminals:

The control terminals do need to be screened when running in parallel with power cables.

(Terminals 7 to 13)

Start/Stop wiring:

Wiring options with push buttons or selector (switch) according to Selection 4.2.
