6. As
sembly
Be sure to connect the motor so as to guarantee a continuously safe
electrical connection (no protruding wire ends); use the assigned ca-
ble end fittings (e.g., cable lugs, wire end ferrules). Select connecting
cables conforming to DIN
VDE 0100, taking into account the rated
current and the conditions of the specific system (e.g., ambient tem-
perature, type of routing, etc. in accordance with DIN VDE 0298-4).
Details regarding electrical connection of the motor to the power
supply, especially terminal and connector pin assignment, can be
taken from the terminal diagram in the terminal box.
WARNING
Electric shock / damage to pump motor
The available mains voltage (supply voltage) must match
the speciications on the rating plate of the motor or of the
electrical components.
It may connected only via a safe galvanic isolation (PELV).
Check the fuse protection of the electrical circuit.
Use only fuses with the prescribed current intensity,
Monitoring equipment that has been triggered (e.g., mo-
tor circuit breaker/fuse) must not automatically switch on
again.
6.7 Electrical motor connection
Consult the motor rating plate for the electrical characteristics of the
motor, such as rated voltage, rated frequency, and rated current.
Observe the guidelines in EN/ISO 60034 (VDE 0530-1) for operation
at the limits of the B ranges (combination of ±10% voltage deviation
and +3/-5% frequency deviation).
This applies especially with regard to heating and deviations in op-
erating parameters from the ratings on the motor rating plate. The
limits must never be exceeded.
IMPORTANT NOTE
Refer to the enclosed operating instructions from the motor manu-
facturer to connect the ATEX motor of the gerotor pump unit. The
information contained therein must be observed.
WARNING
Electric shock
Electrical connections for the product may only be estab-
lished by qualified ATEX personnel authorized to do so by
the operator. The local electrical operating conditions and
local regulations (e.g., DIN, VDE) must be observed.
WARNING
Mains connection for explosion-proof motors
A mains connection in a potentially explosive atmosphere
requires a motor circuit breaker or equivalent protective
device, such as a PTC thermistor with triggering device.
This must be indicated on the motor rating plate together
with release time

WARNING
Damage to pump motor/pump
When establishing the electrical connection of the pump
motor, be mindful of the correct direction of rotation. The
direction of rotation must match the arrow on the motor.
Connect the gerotor pump motor in accordance with the motor con-
nection data sheet from the motor manufacturer. It is located in the
motor’s terminal box (Fig. 17).
