If connected by plug and socket
A special hazard may exist where the actuator is
incorporated into a system connected to the AC supply by
a plug and socket. The pins of the plug are not generally isolated from
the charge stored in the bus capacitor, so must be considered electrically
“hot” until the discharge time has expired. It is the responsibility of the
user to avoid any possibility of electric shock from the pins when they are
accessible.
Grounding - High Leakage Current
The drive must be grounded by a conductor sufficient to
carry all possible fault 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 instructions for ground connections shown in this manual
must be followed.
Compatibility with Residual Current-operated
Protection Device (RCD)
This product can cause a DC current in the protective
earthing conductor. Where a residual current –operated protective (RCD)
or monitoring (RCM) device is used for protection in case of direct or
indirect contact, only an RCD or RCM of Type B is allowed on the supply
side of this product.
Hot Surface – Risk of Burn.
Exposed surfaces of the actuator may exceed 70 degrees
C under normal operation and can take a long time to cool,
resulting in a risk of burns when touched.
