8. Installation and Connection
CAUTION
Risk of damage to unit due to unauthorised modification
of pump!
X
Unauthorised modification will invalidate the warranty.
Under normal conditions, this pump is self-sealing and self-
priming in action. Therefore, valves are not required on the
suction or discharge lines.
X
If pumping against a positive pressure, a non-return valve
must be installed immediately after the pumps discharge
outlet in order to prevent a reverse flow of fluid into the
cartridge in the event of tube failure.
8.1 Electrical Installation
CAUTION
Failure to follow safe and proper electrical installation
practices may result in pump malfunction or dangerous
operation.
X
Make sure the pump is installed correctly.
X
The pump is supplied with a pre-fitted mains lead which
may have a fuse fitted (country dependent); in the event
of fuse failure, replace with the same fuse rating.
X
Ensure that adequate air flow is maintained around the
unit.
X
Do not block the IP66 breather on the rear of the unit.
8.1.1 Checking the ambient conditions
1. Make sure that the operating conditions are as per pump
specifications - see 6.4 Operating Conditions
2.
Make sure the required ambient conditions are within limits
8.1.2 Connecting to the mains supply
DANGER
Risk to health in case of electric shock!
Isolate mains supply from the pump before undertaking the
installation.
This unit will operate from a mains voltage between 100-240V
50/60Hz AC and must be connected to a single phase, mains
electric supply.
1.
The pre-fitted (moulded) plug must not be removed.
2. The pump must not be used if there is visible damage to
the mains cable or plug.
3. The pump must be positioned so that the isolation point is
easily accessible.
4. The mains cable must be free from strain and the pump
weight must not be supported by the mains cable.
5. Do not attempt to use the motor shaft or shaft screw for
PAT / continuity testing as this may damage the unit.
6. Do not apply current to the motor shaft / shaft screw.
Note
It is recommended that a commercial grade mains voltage
surge suppressor is used where is there is an increased risk of
excessive electrical noise entering the unit.
8.1.3 Protective earthing/ grounding
X
The pump is designed to be permanently earthed and
MUST
be connected as such.
X
By default, the earth connection is made through the
earth pin on the mains lead.
X
If the earth connection is removed / not used, EMC
compliance cannot be guaranteed.
X
The PAT connection earth point should not be used to
permanently connect the pump to earth
Do not use the PAT connection earth point for anything other
than PAT / continuity testing!
8.2 Electrical Isolation
1. The mains plug is the disconnection point for the pump and
is used for isolation from the mains.
2. The mains plug should therefore be readily accessible in
order to use as a disconnection point.
3. To isolate the pump, the mains plug is to be removed from
the wall outlet.
8.3 External Control (Ds500+)
Recommended max. cable length between this unit and
external connected equipment is 30 metres.
