Electrical power connection
PS20 Non Stop melters are designed to be connected to the electrical power
supply in one possible way, depending on their power consumption:
• 3-phase 400 VAC with neutral.
A good ground connection is required in all cases.
Consumption figures, according to melter and output configuration, are
included in the table.

Warning: Risk of electrical shock. Carelessness may cause injury or death.
Install the electrical wall bushing Pg 21 in the area reserved for them,
fastening them to the plate with the appropriate nut.
Open the electric cabinet door as far as possible. Thread the power cord (Ø14-
18 mm) through the electrical wall bushing Pg 21 and fasten it to the inside
anchor, making sure that the cord reaches the power terminals block inside
the cabinet.
Connect each wire in the power cord to its corresponding place on the power
terminals block, as shown in the figures.
Pneumatic connection
If a pneumatically controlled by-pass pressure control valve is installed, the
equipment must have a compressed air supply.
Before connecting the pneumatic power to the melter, make sure the pressure
regulator is completely closed. To do this, turn the regulator handle located on
the equipment base next to the pressure gauge counterclockwise as far as it
will go.
Connect the plant air supply (max. 6 bar) to the melter intake using flexible
tubing with an outside diameter of 6 mm. The equipment is provided with a
quick coupling for this purpose.
