VTS300
3-PHASE SLAVE REGULATOR
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.

3. INSTALLATION
3.1. INSTALLATION
Vertically install the device with the wire inlet facing down. To permit
correct heat dissipation, guarantee ≥150 mm clearance over and under
the regulator.
Reassemble and make sure the external protection lid is fully closed.
3.2. Electrical connections
Flexible wire section.
Signal: rated section 1.5 mm² (15 AWG)
Power: VTS 308 ≥ 1.5 mm² (15 AWG)
VTS 312 ≥ 2.5 mm² (13 AWG)
VTS 320 ≥ 4.0 mm² (11 AWG)
N.B. Protection devices: see point 8.
