3.8.1
Residual Current Circuit Breaker, RCCB (Ground fault circuit breaker)
The built in RCCB type B protects from electric shock in case of damaged or broken cables, connectors, etc. If the
RCCB trips, input power will be shut off.
3.8.2
Electrical supply from mains/grid
Connect the Pentpak 3 power pack to a 5 pin 380 - 480 V, 50-60 Hz, 32A socket 3-phase supply with Protective Earth
(PE), minimum 16 Amp fuses. A neutral-line is NOT required. To be able to extract maximum power from the RS2 wall
saw, 32 Amp fuses are required.
The power pack is equipped with a 32 Amp receptacle. To use other sizes than 32 Amp plugs an adapter must be
used.
!
Important!
Check that all cables and connectors are undamaged and in faultless condition.
Make sure all connectors are clean and dry. Do not lubricate the pins and sockets
since they then will attract more dirt than when clean and dry.
3.8.3
Electrical power supply from mobile generator
It is important that when a mobile generator set is used, it complies with the recommendations. See technical data
for details about required size of mobile generator. Do not power any other machinery from the mobile generator
set at the same time as the RS2.
!
Important!
If the mobile generator’s electrical capacity is too low, there is a significant risk of
destroying power electronics in the Pentpak 3.
3.8.4
Requirements for the electrical supply according to EMC directive
This machine is OK to install on any socket connected to a supply with a large enough short circuit power. It complies
with IEC 61000-3-12 provided that short-circuit power SSC at the interface point between the user’s supply and the
public supply network is greater than or equal to 350 MVA.
It is the responsibility of the installer or operator of the machine to ensure, by consultation with the supply network
operator if necessary, that this device is connected only to an interface point with an SSC rating greater than or equal
to 350 MVA.
3.8.5
Extension cable
An extension cable may be used. The size must be adequate for the length:
•
Extension cable 1-50 meters: min 6 mm
2
CU (10AWG)
•
Extension cable 50-100 meters: min 10 mm
2
CU (8 AWG)
