LR18i ground stacking

The maximum allowed number of cabinets in ground stacked mode with GRD18i is six.

Make sure that the array is assembled on a flat and stable surface

Required tools: Allan key wrench 5mm, thin 13mm wrench, long 13mm combination wrench and torque wrench 5-20Nm.

Place the GRD18i(1) on a flat and stable surface. Begin with the first cabinet. Use the supplied locating bolts and black locking nuts for the front couplers(2).

Align the A/B hole with the "A" hole in the angle frame(5) with the collar bolt(6) and the 0,5°/hole GRD18i to the 0° or -2,7° on GRD18i. Pin the long M8 bolt and

slide the black bushing onto the bolt end. Lock the connection with the black locking nut.

Make the first inter-cabinet connection. Align the front coupler holes and pin with the locating bolt and locking nuts. Due to the tight space, a thin wrench is

preferred. A "long nose plier" can also be used, to align and screw the nut onto the locating bolt->15Nm.

Make the correct angle connection. These are stated on the angle frame. use the collar bolts(6) for the angle connection. Tighten up the bolt connections-

>15Nm . Repeat these steps for the remaining cabinets.

When the assembled array has been raised, check all bolt connections.
