5.5.1 Connection to the Electric Service
WARNING!
Should the user change the electrical connection, for example for fitting into a system,
then this may only be performed by an electrical specialist under observance of the
accident prevention regulations.
It is generally suggested to protect the motor by 120 per cent of is rated power in
consideration of the starting and switch-on response.
Device connection cables and plugs must comply with the requirements of the line
disconnection devices (current, output).
The customer/user shall install the main and emergency stop switches.
C65 are supplied with PTC embedded three phase motor but without
accessories for electrical connection. They must be connected via the appropriate
cable and a suitable motor protection switch or PTC module to protect the motor
from overheating in some emergency cases.
Set the switch in according with the rating on the motor nameplate.
After connecting the motor and after every time you alter the wiring, check the
direction of rotation. To do so, briefly switch on the power and check whether a
suitable cover (e.g. a blank flange) is sucked on at the intake port. If not, interchange
two phases of the connection. Observe the direction arrow on the motor adapter.
