FC/BCD-2800 F & I Guide
Now the vacuum cubicle can be placed. To do so:
1. Using a forklift, lower the vacuum cubicle to the floor near the spot where it is to be
permanently located. Figure 3-4 shows the precise locations of the vacuum cubicle’s
casters, leveling feet, and seismic brackets. Referring to Figure 3-2, verify that there
are adequate clearances for the other equipment that will be installed nearby. Take
care to allow enough space so that all doors or maintenance panels can be opened
fully. If you are installing the vacuum cubicle through a clean-room wall, make sure
that that wall does not obstruct the opening of the vacuum cubicle’s doors and
maintenance panels or prevent them from opening all the way.
2. Roll the vacuum cubicle on its casters to its permanent position.
3. Level the cubicle as necessary. Some systems have leveling legs that can be
screwed down to accomplish this task.
3.2.3
Positioning the Operator Station
The operator station will normally be placed immediately to the right of the vacuum
cubicle, as shown in Figure 3-2. The operator must have ready access to the system
controls and be able to open and close the bell jar lid in an unobstructed fashion.
3.2.4
Installing the Power Distribution Box (PDB)
The PDB is normally mounted on a nearby wall. To ensure unobstructed access as
cables are being fed through the bottom of the box, It should be mounted at least 12
inches (305 mm) above any obstructions. The recommended distance from the floor to
the bottom of the box is 32 inches (815 mm). Figure 3-3 shows the PDB’s dimensions
and its mounting hole locations. Mounting hardware for the PDB is customer supplied.
On systems supplied with 208-V ac power, the PDB will weigh approximately 176 lbs. (80
kg). On systems supplied with 400-V ac power, a transformer will be included in the PBD,
increasing its weight to approximately 300 lbs. (136 kg). Such systems also include a
step-down transformer external to the PDB. Perform the following procedure when
installing this transformer:
1. Remove the step-down transformer from its packaging.
2. Place the transformer on the floor in its mounting location, which must be within 6 feet
of the PDB. If required to do so by local codes, secure the transformer to the floor,
using customer-supplied hardware.
3. Connect power Drop #1 to the input of the transformer.
4. Using the Temescal-supplied cables, connect the transformer’s output to the input for
Drop #1 in the power distribution box.
In nominal 208 V ac installations, connect both Drop #1 and Drop #2 to the PDB, as
shown in Figure 3-6. In nominal 400 V ac installations, connect power Drop #2 directly to
the PDB (see Figure 3-7). Before the facility power is actually connected to the PDB,
make sure the main power switch on the box is locked in the OFF position. That switch
must remain locked in that position until the system is ready to be energized by (or under
the supervision of) the Temescal service representative.
NOTE: Do NOT energize the system or any of its components at this time.
3.2.5
Installing the E-Beam Power Supply
1. Install power Drop #2 and connect it to the power distribution box, but do not connect
the HV power supply to that drop. The Temescal service representative will oversee
connection of the power supply to Drop #2.
