1. To prevent the risk of electric shock power supply
to the equipment must be kept OFF while doing the
wiring arrangement.
2. Wiring shall be done strictly according to the
terminal layout with shortest connections. Confirm
that all connections are correct.
1. To ensure the safe operation of unit, check the
wiring and connections.
All safety related codifications, symbols and
instructions that appear in this operating manual or
on the equipment must be strictly followed to ensure
the safety of the operating personnel as well as the
instrument.
If the equipment is not used in a manner
specified by the manufacturer it might impair the
protection provided by the equipment.
If there is physical damage to the unit then do not
use it.
Read complete instructions prior to installation
and operation of the unit.
