About these operating instructions

This symbol gives you useful additional information on assembly or
operation.
The Australian Regulatory Compliance Mark (RCM) is a single
compliance mark used by suppliers after establishing compliance with
all applicable regulations, including EMC, telecommunications, radio
communications, electromagnetic radiation (EMR) and electrical safety.
Protection class II
Electrical appliances in protection class II are electrical appliances that
permanently have double and/or reinforced insulation and do not
have any connection options for a protective earth. The housing of an
electrical appliance in protection class II that is enclosed in insulated
material can partially or fully act as the additional or reinforced
insulation.
Protection class III
Electrical appliances in protection class III are electrical appliances built
for operation with safety extra-low voltage that have neither internal
nor external electricity circuits which work with a different voltage
other than safety extra-low voltage. The maximum rated voltage for
the safety extra-low voltage between the conductors and between the
conductors and the earth is 42 V. In the case of three-phase alternating
current, the maximum rated voltage between the conductors and
the neutral conductor is 24 V. The maximum off-load voltage must not
exceed 50 V. The safety extra-low voltage may only be supplied via a
safety transformer or a transformer with separate windings.
Indoor use
Appliances with this symbol are only suitable for indoor use.

Polarity symbols
On appliances with barrel connectors, these symbols indicate the
polarity of the plug. There are two variants for the polarity: either the
inner contact is positive and the outer contact is negative (Fig. A) or
the inner contact is negative and the outer contact is positive (Fig. B).
Please follow the guidelines in the operating instructions.
