1. PREPARATIONS
1.1.Important
Read these instructions carefully before installation.
Before use, follow all the installation and electrical connection
instructions.
Keep these instructions with the regulator for future use.
Observe current technical and safety regulations.
The device must be professionally installed and commissioned by a
qualified technician. INCORRECT installation may cause damages.
Before turning on device power, always check that it is correctly
grounded.
DO NOT tamper with or REMOVE internal regulator components;
this NULL AND VOIDS THE WARRANTY and can cause damages.
The user must be protected against electrical shock and the motor
must be equipped with overload protection, as per current pertinent
regulations.
According to safety regulations, protection against any contact with
live parts must be ensured by correct device installation; all parts
that ensure protection must be secured so as irremovable without
the help of a tool.
DO NOT turn on the regulator without the protection lid.
NEVER touch electrical circuit parts when the power is on.
Install the regulator away from direct sunlight so as not to overheat
the case.
Make sure working conditions (working temperature, humidity, etc.)
are within the indicated limits (see point 7).
Do not install the device near heat sources (resistances, hot air
ducts, etc.) where room temperature can exceed 50 °C, devices
that generate strong magnetic fields, sites subject to rain, humidity,
dust, excessive mechanical vibrations or shocks.
2. VTS300 REGULATOR UNIT DESCRIPTION
2.1.Overview
The VTS series three-phase regulators are built on a Vetronite(R)
support in an IP55 grade GW PLAST box. The control zone is at the
top of the board while the power zone is at the bottom.
In addition to the M3 and M4 terminal boards, regulation, connection
and signal devices are found in the control zone.
The fan speed command varies according to the command signal
received from the input. Output increases as input increases.

5. Trimmer Regulation limits
5.1.Regulation limits
Trimmer Label Description
P1 MIN/
CUT-OFF
Use as minimum voltage (MIN)
DSw4 = OFF (range from 0-100%).
Turn P1 clockwise to the required
minimum voltage.
Use as CUT-OFF
(shutdown point)
DSw4 = ON (range from 0-100%).
Once the minimum voltage is set, turn
DSw4 ON and press SB1 (reset). Cut-Off
will be set to minimum voltage.
P2 MAX
Maximum speed limit settings (range 0-
100%).
Settings procedure if maximum regulator
speed input signal is not available:
Remove signal connections from M3.
Set the regulator in
0-10 Vdc mode (see point 3.3.2)
Short circuit IN with VR (M3 terminals 1
and 4). The regulator runs at maximum
speed.
Turn P2 counter-clockwise to set the
required maximum voltage.

8. CIRCUIT BREAKER AND SHORT CIRCUIT PROTECTION
A short circuit and/or overload device must be installed upstream from the
VTS308, VTS312 or VTS320 regulator; this protection must be supplied
by the installer and can be made up of:
Three-phase circuit breaker with ‘AC’ cut-off curve
Triple ultra-fast fuses, to protect semi-conductors

VTS312 24 A 10x38 16 FR10GB69V16
VTS320 40 A 14x51 25 FR10GB69V25
The use of these protections safeguard regulation device electrical
integrity.
SURGE ARRESTER :
Electrical protection inserted between the regulator power supply and
grounding, that protects the device from transitory power surges up to 480
Vac.
WARNING:
Disconnect the faston contact from the PE ground reference, in the
electrical rigidity test.
WARNING:
For DIFFERENTIAL protection systems, use components with grounded
current dispersion ≥60 mA.
The VTS300’s dispersion current to Ground, it’s about 4 mA
