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
Model Circuit breaker Protection fuses - SRC
Type Vac Amp P/N
VTS308 16 A 10x38
690
16 FR10GB69V16
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
