7.3 Electrical Installation
WARNING
Risk from electric shock!
Electrostatic charges can inflict fatal injuries.
Customised installations:
The use of external product tanks
equipped with supplementary mechanical ventilation and/or
liquid transfer pumps may create risk of electrostatic shock.
The design of storage and transfer systems should be risk
assessed by a competent person.
Additional earth bonding arrangements may be required in
accordance with local electrical codes.
All electrical work must be carried out by a trained electrician.
7.3.1. Wiring the PSU cabinet and EASYCHLORGEN control
panel
Precondition for action:
PSU cabinet and EASYCHLORGEN located correctly
Identify system model/type
Perform the following working steps:
1.
Wire in accordance with the wiring diagrams detailed later in
this section for the corresponding model ensuring that the
electrical installation is suitable for the voltage and kW rating
of the unit, as indicated on the machine identification plate.
Refer to Technical Data section 5.1 and 5.2.
2.
Connect a mains 3-phase AC + Neutral power supply to the
PSU cabinet isolator connection block. A cable, conduit or
electrical trunking connection will need to be carried out by
an electrician for suitable entry of the electrical supply
through the lower section of the PSU cabinet panel as
detailed in 4.2.3.
3.
Earth the device in accordance with local regulations.
4.
Interconnect the 115VAC power supply cable from the PSU
cabinet to the EASYCHLORGEN control panel mains power
isolator connection. A 2C+E cable is factory fitted at the
PSU cabinet for this purpose and may be replaced to
comply with local regulatory requirements.
5.
Interconnect the 3-phase AC power supply from the PSU
cabinet to the EASYCHLORGEN air blower rotary isolator.
A 3C+E cable is factory fitted for this purpose and may be
replaced to comply with local regulatory requirements.
6.
Interconnect the multi-core signal cable from the PSU
cabinet to the EASYCHLORGEN control panel. A multi-core
cable is factory fitted for this purpose and may be replaced
to comply with local regulatory requirements.
7.
Interconnect the 2-wire screened signal cable pre-wired at
the EASYCHLORGEN control panel to the corresponding
terminals at the PSU cabinet. A screened cable is factory
fitted for this purpose and may be replaced to comply with
local regulatory requirements.
IMPORTANT!
Only earth
the signal cable screen at the EASYCHLORGEN control
panel and NOT at the PSU cabinet.
8.
Interconnect the M12 yellow cable assembly to the
EASYCHLORGEN control panel and the hydrogen gas
detector. An M20 connection point on the underside of the
control panel is provided for this cable route.
9.
Connect the external product tank stop level switch cable
assembly to the EASYCHLORGEN control panel. An M20
connection point on the underside of the control panel is
provided for this cable route.
10.
Interconnect any auxiliary wiring (for devices supplied
outside the scope of the standard system) using the spare
cable glands provided.
11.
IMPORTANT!
Inside the PSU cabinet, locate the isolating
power transformer, ref. XF-1. This transformer allows a
wide range of 3 phase supplies to be accommodated and
provide a fixed 115VAC single phase supply to the
EASYCHLORGEN Control Panel.
Connect the voltage
setting LINK WIRE/S according to the local 3Ø supply
voltage as detailed in the table below. Failure to select
the correct linkage may result in permanent damage to
the EASYCHLORGEN control panel PCB!
DANGER!
Mortal danger from electric shock!
Live parts can inflict fatal injuries.
Disconnect from the electricity supply before working on
any equipment and secure all devices to prevent it from being
switched on again.
