e-IXP, e-IXPC, e-IXPF series – Additional Installation, Operation and Maintenance Instructions
DANGER: Electrical hazard
Connect all the electrical accessories of the unit to the ground.
DANGER: Electrical hazard
Check that the external protection conductor (ground) is longer than the phase conductors. In
case of accidental disconnection of the unit from the phase conductors, the protection
conductor must be the last one to detach itself from the terminal.
DANGER: Electrical hazard
Install suitable systems for protection against indirect contact, in order to prevent lethal electric
shocks.
4.6.2
Guidelines for electrical connection
1.
Check that the electrical leads are protected against:
•
High temperature
•
Vibrations
•
Collisions
•
Liquids.
2.
Check that the power supply line is provided with:
•
A short circuit protection device of appropriate size
•
A mains disconnection device with contact opening distance ensuring complete
disconnection for overvoltage III category conditions.
4.6.3
Guidelines for the control panel
1.
Install appropriate devices for protecting the motor from overloads and short circuits:
•
Thermal protection: trip class 10 A overload thermal relay + aM fuses (motor start-up), or
start class 10 A motor protection thermal magnetic switch
•
Protection from short circuit: aM fuses (motor start-up), or thermal magnetic switch with
C curve and Icn ≥ 4.5 kA, or other similar device.
2.
If required, install phase failure sensitive thermal relays.
4.6.4
Motor connection
1.
Open the terminal box cover.
2.
Insert the power cable in the cable gland.
3.
Unsheathe the conductors.
4.
Make sure that the protection conductor (ground) is longer than the phase conductors.
5.
Refer to the wiring diagrams in the figure or inside the cover, insert the cores of the
conductors into the respective holes and tighten the nuts or screws.
6.
Tighten the cable gland.
7.
Close the cover and tighten the screws.
