4 Power and Grounding Requirements

4.1 Requirements for ground cables provided by the customer

• A wall circuit breaker or equivalent device with LOTO capability must be installed on the Main
Power. This device must be compatible with the power input specifications of the system.
Procurement, delivery and installation of this breaker is customer responsibility.
• The customer shall provide the ground wire between the EMI filter (for Fluoro UPS CE option
only), PDB (Power Distribution Box) and earth. Impedance of the ground wire to earth shall be
lower than 2 ohms (refer to direction 46–019668 for method of measurement).
• The ground wire to earth shall be a minimum of AWG 2/0 (UL) or 35 mm 2 (CE) or the same
size (100%) as feeder wires, which ever is larger.
•
The shield of any shielded cable coming from the distribution cannot replace the ground wire.

4.2 Requirements for power supply cables provided by the customer

The customer shall provide the power supply cables between the main transformer and the system:
• between the transformer and the PDB (Power Distribution Box),
•
between the transformer and the EMI filter (for Fluro UPS CE option only),
• between the EMI filter and the PDB (Power Distribution Box) (for Fluro UPS option only) (max
length = 3 m),
• between the PDB and the Jedi (max length = 24 m),
• between the PDB and the C1 cabinet (max length = 24 m),
•
between the PDB and the tube chiller (max length = 24 m),
• between the PDB and the Fluoro UPS (Fluoro UPS option).(max length = 24 m),
• between C1 and C2 cabinets (max length = 6 m)
The power supply cable between the main transformer and the PDB (Power Distribution Box) and
between the PDB and the Jedi shall be sized to insure proper voltage drop.
Table 6-2:

Ω
The power supply cables provided by the customer shall be sized according to the Illustrations
AC Interconnect without Fluoro UPS and AC Interconnect with Fluoro UPS in
Distribution.

4.3 Requirements for all power supply and ground cables provided by the customer

•
Power supply and ground cables shall be dedicated to the system. They must not be used to
supply other systems.
• Power supply and ground cables shall be kept separated from room system cables.
•
Power supply and ground cables must be connected to the same distribution panel. They must
run near one to the other.
