Reconfigure the iH system for your electrical supply (if necessary)
CAUTION
iH160/1000/1800 systems are supplied already configured for your electrical supply. The iH system cannot be
reconfigured between the low voltage (200 V to 230 V) and high voltage (380 V to 460 V) ranges.
Contact your supplier or Edwards if you wish to use the iH system with a power supply in a different voltage range to
that specified on the rating plate. To reconfigure the iH system within its standard voltage range, refer to
Figure 9
and ensure that the correct transformer primary tapping is selected using the following procedure:
Ensure power supplies to the iH system are disconnected.
Undo the screws (2) which secure the cover (1) to the Electrics Box (3) and remove the cover.
Ensure that the common cable (4) is correctly connected to the common terminal on the terminal-block (6).
Ensure that the voltages select cable (5) is connected to the correct voltage terminal of the terminal-block (6) for
your electrical supply.
Refit the cover (1) and secure with the two screws (2).
3.8.2
Reconfigure the iH system for your electrical supply (iH80/600 only)
If you want to use an iH80 or iH600 system with a different electrical supply, use the following procedure:
1. Refer to
Figure 10
. Undo and remove the six screws which secure the rear cover over the HCDP pump-motor, and
remove the rear cover.
2. Undo and remove the four screws which secure the cover to the pump-motor terminal-box.
3. Look at the links in the terminal-box (1):
z
For high voltage operations (380-415 V at 50 Hz or 460 V at 60 Hz), ensure that the links (2) are in the
positions shown in
Figure 10
.
z
For low voltage operations (200-208 V at 50 Hz or 200-230 V at 60 Hz), ensure that the links (2) are in the
positions shown in
Figure 10
.
4. Refit the cover to the pump-motor terminal-box and secure with four screws.
5. Refit the rear cover and secure with the six screws.
6. If you have iH600, continue at
Step 7
, otherwise continue at
Section 3.8.3
.
7. Undo and remove the four screws, which secure the electrics box to the rear of the iH system, then carefully
lower and support the module. Ensure that you do not disconnect, break or damage any of the cables connected
to the module.
8. Carry out steps
2
,
3
and
4
.
Refit the electrics box to the rear of the iH system and secure with the four screws: ensure that you do not trap any
of the cables connected to the electrics box.
