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.
