shake proof washer located on the front of the pump housing to secure the
earth conductor to the pump. Refer to
.
Disconnect the pump from the electrical supply.
Isolate the Mains supply before removing the physical electrical supply
connection to the pump, via the IEC 60320 cable (C19).
The 1-phase pump comes supplied with a V-lock IEC connector. This is a
latching type connector and does not require a tool to disconnect the mains
to the pump. In accordance with IEC 61010-1, the mains input cable must
be kept to a maximum length of 3 m, there must be a suitable means to
unplug the mains plug at the customer’s supply source.
6.6.1Connection for remote control and monitoring
To operate the pump using parallel control, use the 15-pin D-Sub connector
on the user interface panel.
6.6.2Connect the logic interface to the control equipment
The pump can be controlled using a hardware parallel control interface.
To control the pump using the hardware parallel interface, refer to
on page 38 for more information.
6.7Electrical installation 3-phase
WARNING: HAZARDOUS VOLTAGE
Risk of electric shock. Make sure that the electrical installation of the 3-phase
pump system conforms to local and national safety requirements. The electrical
Installation needs to be carried out by a trained electrician.
CAUTION: PUMP DAMAGE
Risk of damage to pump. The 3-phase pump must be installed with motor thermal
overload protection, failure to install could result in permanent damage to pump
Fuses and circuit breakers
The 3-phase pump system is suitable for Installation Category II as dened
in IEC 60664-1. The pump system must be connected to an isolator that
disconnects all curr
ent carrying conductors and can be locked out in the off
position (LOTO). The isolator must be in close proximity to the equipment,
within easy reach of the operator and identied as the disconnect device for
the equipment.
Prior to operating the 3-phase pump system; make sure that the pump
is supplied with the correct external branch circuit protection. The 3-
phase pump system is dened as “multiphase, permanently connected
equipment”, and it does not include internal fuse protection for the overall
pump system. There is internal fusing for the low power branch circuits
within the pump system, however the overall pump system must be fused
externally as part of the installation procedure.
species the required fusing to protect
the 3-phase pump system in the event of a fault. In addition to this fusing,
