Setting up
Set up the Powerbox at a distance suitable for your work on a level surface, so that you can work
comfortably without the risk of tripping over the Powerbox.
5.2
Mains connection
Attention
Check whether the mains voltage matches the voltage given on the information
plate.
Remove the protective covers on the plug sockets. These protective
covers are designed to protect the socket against the ingress of
water when the plug is not connected. This significantly increases
the service life of the high-quality cable sockets.
First connect the electrical connection cable to the flange socket
found on the front of the Powerbox. Check that the connection cable
is properly connected. Only this will give you the required IP 67
protection. The connection cable used (400 V 3~ or 230 V 1~)
determines whether the Beluga drive unit operates at 230 V, 1~,
4,000W or at 400 V, 3~, 8,000 W. Connect the Powerbox PB RX /
SX 12 to the mains via an upstream, all-current-sensitive residual
current circuit breaker or safety transformer and coded CEE plug 6
h.
Only use extension cables with earth conductors and of sufficient
diameter. If the diameter is too small, this may lead to excessive
power loss and to overheating of the motor and cable. An extension
cable must be protected by an overload switch. Recommended wire
diameters:
Rated current = 15 / 20 A

Powerbox water connection
The Powerbox can be operated air-cooled as well as water-cooled. The air connection normally suffices for
the 8 kW drive units. The water must first flow through the Powerbox, then through the drive unit and only
then to the saw blade or the drill bit. Therefore, connect the water supply to the water line (with tap)
provided on the Powerbox. The water outlet of the Powerbox is connected to the water inlet of the drive
unit.
Attention: If possible do not exceed maximum water pressure of 3
bar
During operation, always supply sufficient cold cooling water (cooling
water should not exceed 30 °C). The machine must be operated
during full load operation with at least 1/2 litre of water per minute.
Only use clean tap water, no contaminated or waste water, since
otherwise the heat transfer to the cooling surfaces is no longer
guaranteed and the motor may suffer irreparable damage.
