Table 2-3 Procedure for Mounting Recorder with NEMA4 or Heavy Duty Door
Step Action
1
Place the panel gasket onto the rear flange of the recorder case.
2
Install four #8-32 screws on each of the three mounting brackets so the ends of the screw
threads are flush with the face of the bracket.
NOTE: Screw heads to be flange side of brackets.
3
Insert the case with gasket into the panel opening.
4
Install one left hand and one right hand bracket with 1/4 x 3/8 long bolts and lockwashers on
each side of the case.
NOTE: The notch on each bracket should be facing upward towards the top of the unit.
Do not tighten the hex bolts at this time.
5
Install the remaining right hand bracket on the top with the 1/4 x 3/4 long bolt and lockwasher.
Do not tighten the bolt at this time.
6
Place a screwdriver blade on the notch of each bracket and firmly tap so that each bracket
firmly mates the case with gasket to the panel.
NOTE: Keep brackets parallel to case. Tighten the three 1/4 hex bolts to hold the brackets in
place.
7
Start to tighten the #8-32 x 1/2 screws on the right side bracket. Alternate screws at opposite
ends until all four screws have a minimum of 10 lb-in of torque applied. Do the same to both
the left side and top brackets.
When completed all twelve screws should have a minimum of 10 lb-in of torque applied. This
assures the case and panel gasket are adequately sealed against the panel.
