Supply isolation
The AC supply or high voltage DC supply must be
removed from the actuator using an approved isolation
device or disconnect before any servicing work is
performed, other than adjustments to the settings or parameters
specified in the manual. The actuator contains capacitors which remain
charged to a potentially lethal voltage after the supply has been
removed.
If connected by plug and socket
A special hazard may exist where the actuator is
incorporated into a system which is connected to the AC
supply by a plug and socket. When unplugged, the pins of
the plug may be connected to the drive input, which is only separated
from the charge stored in the bus capacitor. It is the responsibility of the
user to avoid any possibility of electric shock from the pins, if they are
accessible.
Grounding - High Leakage Current
In the event of a fault, this equipment has high earth
leakage current. You must comply with local safety
regulations with respect to minimum size and special
installation requirements on the protective earth conductor for high
leakage current equipment. The ground connections shown in this
manual must be followed.
Fuses and Branch circuit protection
“The Integral solid state short circuit protection does not
provide branch circuit protection. Branch circuit protection
must be provided in accordance with the National
Electrical Code and any additional local codes”, or equivalent. Fuses or
over-current protection must be provided at the input in accordance with
the instructions in the manual.
CAUTION – Hot Surface – Risk of Burn.
