Section 5.0 Electrical Requirements
5.1 Electrical connection of electrical control and power supply:
Units with no factory mounted electrical control, require an electrical control that is made according
to the Nederman regulations must be connected else there is no guarantee on the product.
5.2 Non-line of Sight Operation:
If the collector is operated where its function, or non-function, is not directly visible and where a
defective filter function may lead to a dangerous situation, the operation of the collector must be
monitored by means of a pressure switch providing an immediate malfunction alarm.
5.3 Connection to Power Supply:
•5 hp (3.7 kW), 7.5 hp (5.6 kW) or 10 hp (7.5 kW) electrical motors are used depending on
model. Verify motor and power supply upon receipt of order and consult a certified
electrician or maintenance department for any necessary connection accessories.
•Single phase units requite a motor starter and 208 V or 230 V, 60 Hz power supply.
•Three phase units require a motor starter and 208 V, 230 V, 480 V or 575 V, 60 Hz power
supply (per order) with the necessary amperage for horsepower provided.
5.4 Grounding Instructions:
For collectors with flammable and explosive dust, piping must be made of a material preventing
static electricity. For non-conducting short connection elements, e.g. flexible connections, an
electric wire (min 14 awg (2.5 mm2)) should be mounted on the outside of the connection element
between the pipe ends. For bypassing of static electricity, an additional ground connection should
be established, see figure below.
A : Steel stand of Collector
B : Foundation
C : Earth
D : Connection M10 screw and cable eye
E : Cable connection. 10-4 awg (6-25 mm2) but not
smaller than 50% of the largest conductor connected
to the plant and not larger than 4 awg (25 mm2).
F : Terminal box for earth rod
G : Earth ground rod
-Bigger than 6 awg (16 mm2) with corrosion jacket
-Bigger than 4awg (25 mm2) for copper without jacket
-Bigger than 1 awg (50 mm2) for hot galvanized
D, E, F and G should be bought together for corrosion reasons
