Electrical Installation - IMPPUMPS GHNDbasic II Betriebs- Und Montageanleitung

Pump will provide the longest lifetime with ambient at room temperature and moderate medium temperature. Prolonged
operation at elevated temperatures could increase wear. Aging is accelerated by high power and high temperatures.
Misconnection or overload could cause pump shutdown or even permanent damage.
•
Pumps might be heavy. Provide yourself help if needed,
•
Pump must not be used in the safety pipelines,
•
Pump should not be used as a holder during welding!
•
When reassembling, care should be taken to ensure seal fit. Failing that, water could cause
•
damage to pumps internal parts,
Drains between pump motor housing and hydraulic housing must be left free (should not be
•
thermally insulated), as it could interfere with cooling and condense drainage,
Hot medium can cause burns! The motor can also reach temperatures that could cause injury.

ELECTRICAL INSTALLATION

GHN basic II, GHND basic II and SANbasic II pumps are provided with built-in, three phase electric motor, to be connected with
A.C. mains of 3~400 V, 50 Hz. GHNMbasic II, GHNMDbasic II and SANbasic II type pumps have built-in, single phase electric
motor 1x230 V, 50 Hz.
There is a bimetallic switch located inside the motor winding. Based on the state of the bimetallic switch, the external
monitoring system can shut off the pump if it becomes too hot.
The protective device for disconnecting all poles from the power supply network must be installed in the electrical installation in
accordance with national installation regulations.
The motor protection switches Iskra MIS MS 25, Schrack ALEA or similar switches are appropriate fuses.
The connecting wire has to be connected over a cable entry M20 (Fig. 1 - POS. 7).
Connection leads should be capable of carrying rated power and should be properly fused. Ground lead connection is essential
for safety. It should be connected first. Grounding is only meant for pump safety. Pipes should be grounded separately.
Connection of the pump must be carried out by qualified personnel,
•
• Connection of the connecting cable must be done in a manner that ensures it is never in contact with the
casing of the device, due to the high temperatures of the casing,
This appliance can be used by children aged from 8 years and above and persons with reduced physical,
•
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way and understand the hazards involved,
Children shall not play with the appliance,
•
• Cleaning and user maintenance shall not be made by children without supervision.
Electrical connections of the pump must be carried out in accordance with the wiring diagram (Fig. 3), attached on the bottom
of motor cover. Before doing that unwind the upper cover (Fig. 1 - POS. 2). By the standard IEC 60446 it is recommended to use
the following electrical wiring order:
L1: brown
L2: black
L3: gray
B1: thermal protection
B2: thermal protection
GND: green with yellow stripe
