Feed the fastening strap
through the back slot
from the outside to the
inside.
Then feed the fastening
strap around the con-
tainer and lash around
the front of the container
in the opposite direction
(see figures).
Please remove the fol-
lowing components in-
cluded in delivery:
• Acid dosing pump
• Resealable bag la-
belled package 6
Package 6: Pump bracket
(1x), nut M4 (4x), gasket
(4x), lock washer (4x),
screws M4x10 (2x)
Then start the individual
assembly steps.
Mount the pump to the
pump bracket before se-
curing it to the container
bracket. This will make
the pump easier to in-
stall.
To do so, mount the
pump to the pump
bracket using the desig-
nated fastening points.
Use the installation ma-
terials from the reseal-
able bag (package 6: nut
M4 (4x), gasket (4x), lock
washer (4x), screws
M4x10 (2x)).
Secure the installation
material with a torque of
2.9 Nm.

4.7 Mounting the Dosing Pump to the Housing

4.8 Electrical connections

The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
An additional, or integrated in the separator, overcurrent
device is required. All feeders except the ELCB must have over-
current devices, e.g. circuit breakers or fuses. This should be
next to each other, have the same rating, and not be integ-
rated in the neutral wire of multi-phase equipment.
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
CAUTION
Equipment damage
Cables damaged
Do not damage the cable during installation. Install a strain
relief for the cable connection. Secure the cable against twist-
ing and loosening. Please note the temperature resistance of
the cables (> 100 °C/212 °F).
We recommend equipping the power and voltage supply with
ELCB.
The ELCB (tripping current 30 mA) must shut off the load
within the prescribed period (200 ms at 115 VAC, 40 ms at
230 VAC). It must be suitable for the maximum load.
Attach the pump bracket
to the designated
threaded bolt on the con-
tainer bracket. Again use
the included installation
materials in the reseal-
able bag (package 6).
Secure the installation
materials with a torque
of 2.9 Nm.
