Environmental Conditions
Pollution Degree : The ZETA6104 is designed for
pollution degree 2.
Installation Category : The ZETA6104 is designed for
installation category II.
Electrical
Connecting & Disconnecting Power Mains
The ZETA6104Õs protective earth connection is provided
through its make-first/break-last earth terminal on the
power mains connector. You must reliably earth the
ZETA6104Õs protective earth connection.
Using an Isolation Transformer
The ZETA6104Õs mains voltage is limited to 120 VAC
nominal. If your mains voltage is higher, use an isolation
transformer located between the power mains and the
ZETA6104. Your isolation transformer should be
insulated toÊ~2300V rms.
Do not interrupt the protective earth conductor between the
source mains and the isolation transformerÕs secondary.
The core of the isolation transformer and the driveÕs
protective conductor terminal must
both be connected to
the mains protective earth conductor.
CAUTION Ñ Do not use an autotransformer.
Adding Line Fuses
Line fuses need to be added to protect the transformer and
associated wiring. If the live wire cannot be readily
identified, fuse both phase conductors. The value of fuse
required is given by: (1.5 x VA)/(supply volts) [amps]
Fuse types should be anti-surge HBC.
WARNING Ñ
Safety Ground (Earth Ground)
should never be fused.
Providing a Protective Earth Connection
for Motors
You must provide a connection from the motor to a
reliable protective earth contact point. This connection
provides a protective earth for the motor, and is
in addition
to the earth connection provided by the drain wire in the
motorÕs power cable. The motorÕs protective earth
connection is important for safety reasons, and
must not
be omitted.
Make connections according to the diagram and
instructions below:
Motor
Safety Earth
Cable
(green/yellow)
1. Use a spade lug in combination with a star washer and
mounting bolt to make good contact with the bare
metal surface of the motorÕs mounting flange.
2. Use a green and yellow striped wire to make the
connection between the motor and earth. Wire gauge
must be no thinner than the current carrying wire in the
motorÕs power cable.
3. Resistance between the motor and earth must be no
greater than 0.1
W
. Use thicker gauge wire if the
resistance is too high.
