3. According to IEC 60204-1, paragraph 5.3.2, the plug on the main supply cable is
known as the “supply disconnecting device.” To comply with this regulation the
unit must be connected to the main power supply by means of this plug-socket
combination.
Before connecting the main power cable, make sure that the supply voltage
matches the specifications on the nameplate on the back of the cabinet.
4.
See figure 8. Fit the cooling water supply to the inlet and outlet water tailpieces.
Make sure that the water supply is connected to the inlet and the water return to
the outlet.
5.
Check that the cooling water circuit is ready for use (pumps turned on, external
valves open, etc.) and that the inlet water temperature is below 35°C/95°F.
6.
See figure 8. If the external control unit (ECU) is in use, connect it to the signal
plug socket(s), X9 and/or X9.1, at the rear of the converter. For Twin versions,
the signal plug sockets for HHT 2 are X10 and/or X10.1.
7.
When using an ECU, make sure that the LOCAL/REMOTE selector is in the
correct position, i.e., at REMOTE. Otherwise, it should be positioned at LOCAL.
