•
You must ground (earth) all
electrical equipment. This
applies to the pump
equipment, the motor, and any
monitoring equipment. Test
the ground (earth) lead to
verify that it is connected
correctly.
•
If the motor cable is jerked
loose by mistake, the ground
(earth) conductor must be the
last conductor to come loose
from its terminal. Make sure
that the ground (earth)
conductor is longer than the
phase conductors. This
applies to both ends of the
motor cable.
•
Add additional protection
against lethal shock. Install a
high-sensitivity differential
switch (30 mA) [residual
current device RCD].
4.1 Motor (ATEX classification)
The pump without the motor is suitable for:
•
ambient temperature between
-10°C (+14°F) and +55°C (+131°F)
•
gas temperature class of T4 (+135°C =
+275°F)
•
gas explosion group of IIC
When you purchase a motor, check its ATEX
classification and combine it with the classification
of the pump.
Here some examples for informational purposes only.
