on this machine or in these user instructions are ignored or not followed. Read the
entire user manual before you use the machine.
DANGER: Failure to properly ground the Bona
®
Power Station Plus can result in
serious injury and death.
The Bona
®
Power Station Plus is a buck/boost transformer. It
provides the operator of a 220V wood floor sanding machine the
opportunity to buck down or boost up the voltage as needed to
provide the optimum voltage required to operate the motor on
the sanding machine properly. Bona sanding equipment requires
230V service as the optimum power feed.
The Bona Power Station Plus also provides a 110V duplex outlet
located on the unit's front face as a convenience to the end-user
to operate a small hand tool, buffer, or vacuum product. The Bona
Power Station Plus is a four-wire system providing two 110V hot
leads, a neutral return wire, and a ground wire. This four-wire
arrangement allows for the inclusion of the 110V duplex outlet,
which permits use simultaneously with the 220V outlet on the
transformer. When properly connected to a four-wire 220V/230V
service such as a Residential dryer or stove outlet, the Bona
Power Station Plus will operate as intended.
However, when the Bona Power Station Plus is connected to an
existing three-pronged dryer or stove outlet by a three-wire
pigtail setup (two 110V hot legs and a ground wire), the 110V
duplex outlet on the Bona Power Station Plus will be rendered
useless. The 220V motor will run properly in this arrangement and
will be properly grounded.
For the 110V duplex to work and be properly grounded, there
must be a FOURTH wire (the white return wire) to complete the
circuit. Concerning the above-mentioned three-wire pigtail, a
four-pronged female connector can be attached to the end of the
three-wire cable, which can be connected to the four-pronged
male connector coming from the four-wire line on the input side of
the Bona Power Station Plus. Because this three-wire pigtail has
no "return white wire," the 110V duplex will be rendered useless.
If the product user wishes to activate the 110V duplex, the user
must revert to a four-wire arrangement.
A certified electrician must install a four-wire drop with a four-
pronged female NEMA connector to connect to the four-wire cable
and male connector coming from the Bona Power Station Plus. Do
not attempt this if you are not a certified electrician.
Three-pronged dryer and stove outlets were the standard service
outlets for residential construction until around 1998 when NEMA
standards changed to the four-wire system. When using the Bona
Power Station Plus, employ a certified electrician to make any
additional electrical connections to any job site electrical service
that will not allow the sanding equipment operator to connect the
Bona Power Station Plus following the product's intended use.
If the sanding equipment operator chooses to have a certified
electrician prepare an electrical service connection using a three-
wire, three-pronged plug, it must be understood that the 110V
convenience duplex will not be operable.
NEVER connect the neutral and ground wires in a four-wire cable
to accommodate a three-pronged plug. This incorrect connection
can result in electrical shock due to improper grounding.
