Operating instructions
7 Installation
7.1 Installation location
The following criteria must be taken into account when selecting the
assembly location:
n
The installation surface is even.
n
The water sampling station is opened to the left.
n
The installation height is chosen so that the display of the controller is
at eye level for the user.
n
Below the water sampling station there must be at least 20 cm free
space to route the inflow and outflow pipes.
n
Keep ~ 25 cm clearance above the water sampling station so that the
pH and Redox single-rod measuring cells can be removed for
adjustment
n
All pipes and cables can be routed without kinks.
n
From the extraction point, the sample water must reach the
Water sampling station over as short a distance as possible in order to
avoid measured value deviations.
n
Direct sunlight or heat radiation is avoided.
7.2 Wall mounting
This section takes you through the wall mounting of the
Water sampling station
EASYPRO COMPACT
step by step.
Perform the following work steps:
1.
Unscrew the pre-installed wall holder from the water sampling
station.
2.
Attach the wall holder to the wall. The screws supplied are suitable
for masonry.
3.
Align the left side of the wall holder perpendicularly using a water
level.
4.
Hang the water sampling station from the wall holder again and
tighten the screw supplied so they are finger-tight.
ü
The water sampling station is fitted on the wall.
7.3 Electrical installation
The voltage supply to your device can now be performed via a normal
Schuko plug or a control cabinet. Perform the specifications of this
section for devices without a pre-fitted Schuko plug.
Pre-conditions for actions:
ü
The device was installed in accordance with section 7.2 “Wall
mounting” on page 17.
ü
A voltage supply with 100 − 240 V AC (50/60 Hz) is available.
ü
The voltage supply is deactivated before the start and secured
against reactivation.
ü
The housing is open.
Resources required:
@
Schuko plug
@
Wire end sleeves 0.75 − 2.5 mm²
DANGER!
Mortal danger from electric shock!
Improperly installed or damaged components in the electronics
installation can cause injury.
ð
Ensure that all work on the electrical installation is performed by a
qualified electrician.
ð
Ensure that all work on the electrical installation is performed in a
de-energised state.
ð
Ensure that the power supply is secured with a fault current
protective circuit.
ð
Replace damaged cables or components without delay.
Perform the following work steps:
1.
Fit wire end sleeve to the cable ends if the supply cable does not
have them.
2.
Open the device housing.
3.
Lead the supply cable through a cable screw connection to the
underside of the device.
4.
Turn the cable screw connection union nut until the line is fixed in the
screw connection so that the screw connection performs strain relief.
Ensure that the feed cable is installed loosely.
5.
Connect the voltage supply to the clamps 44 − 52. Observe the
division into protective earth (PE), neutral conductor (N) and the
phase (L) on the circuit board.

Only 3 of 9 clamps are required for connection of the voltage
supply. You can use the free clamps to supply further devices
with voltage.
The contact load rating amounts to max. 4A.
