4.2. Variant 2: J-SUB and J8/J12 Arrays
Unlike an array of J-TOP cabinets only with mixed configurations the
cabinets are lifted and attached to the array one by one.
For flown arrays of J-SUB and J8/J12 cabinets two J Flying frames must
be used.
CAUTION!
If the array contains J-SUB cabinets these must always
be positioned at the top of the column.
4.2.1. Preparations and order of assembly
1. Prepare the flying cables and link cables according to the number of
amplifier channels and cabinets used.
2. Decide where to fix the cable pick depending on single or dual hoist
suspension.
Preparation and suspension of the first frame
3. The Splay link of the first frame must be fitted in J-SUB position.
Check the position of the Splay link and alter the position if
necessary as described in section 3.4 Splay link position at the
Z5300 J Flying frameon page 12.
4. Depending on the chosen type of suspension (single or dual hoist set
up as described in section 3.5 Suspension of the Z5300 J Flying
frame on page 13) attach the J Load adapter to the center bar of
the J Flying frame.
5. Connect the hoist(s) to the Load adapter(s).
Attaching the secondary safety device
6. At this point of the set up we recommend to attach the secondary
safety device using the Z5303 J Safety chain set as described in
section 3.6 Secondary safety on page 15.
