VTop Control Valves
M/VTOP-M/E ed. 01 2020
ATTENTION
The yellow and green cables can only be used to connect the ground protection.
When wires are inserted in cable glands, consider the maximum radius of the curve
ATTENTION
The PSL-AMS electrical actuators are equipped with an internal electrical
insulation device, therefore a switch or sectioning circuit must be installed; this switch must be
installed near the valve and must be easily accessible to staff.
It is important to signal the switch or sectioning circuit as the insulation circuit of the actuator/valve
ATTENTION
The electrical installation, as well as the overcurrent and overvoltage protection
systems must comply with the standards DIN IEC 60364-4-41, responsible protection class I,
protection class III(24V AC / 24V DC) and also the standard DIN IEC 60364-4-44 in compliance
with the overvoltage categories of the actuator.
ATTENTION
Mechanically protect all the connection and control cables with specific
measures against the terminals, against accidental release, never install power supply and
control cables together on the same line, but always use two separate lines.
3.4.1 – WIRING DIAGRAMS
According to the dimensions of the actuator, the electrical terminals are positioned inside the “terminals box” or under
the cover. Having completed the connection, close the cover of the terminal box and the actuator well and tighten the
cable glands to ensure protection as outlined in the specifications.
The wiring diagram can differ based on the actuators in the special version.
