INSTALLATION
Caution:
In many cases, the Reversal Switch and DC Power Supply will be pre-installed by
GMW into a 19” EIA equipment rack. If it is not, care should be taken during rack mounting to
avoid personal injury or damage to the equipment.
3.1 - Unpacking Instructions and Damage Inspection
3.1.1 - Systems Shipped with a GMW Supplied Rack:
1. Remove all eight of the lag bolts located at the lower edge of all the side panels of the
crate top cover.
2. Gently rock the crate top cover to work it loose from the shipping crate base.
3. Use one person on each side of the shipping crate grip the side panels of the crate top
cover. Lift the crate top cover high enough to clear top of the rack, walk the cover
sideways to a clear area and place it upon the floor.
4. Inspect the rack and its contents to ensure that no damage has occurred during
shipment. If any damage is evident report the damage in detail to the shipper for
claim and simultaneously notify GMW in case an assessment of the damage must be
made. If no damage is found, proceed with the unpacking and installation.
5. Cut the straps that secure the rack to the pallet base.
6. Remove the wood block at the bottom front edge of the rack.
7. Carefully slide the rack forward and off of the pallet base.
8. Unpack any other system components as per their instruction manuals.
3.1.2 - Systems Shipped without a GMW Supplied Rack:
1. Open the outer shipping carton by cutting the packing tape along the joints.
2. Remove the inner shipping carton by carefully lifting it out.
3. Open the inner shipping carton by cutting the packing tape along the joints.
4. Carefully lift the reversal switch clear of the shipping carton.
5. Inspect the reversal switch for any damage.
6. Retain all packing materials for future shipping needs.
3.2 - Rack Mounting
When rack mounting the 5971-160 Reversal Switch it is important to note that the vertical
mounting flanges alone are not strong enough to support the weight of the Reversal Switch.
Support angles on each side, beneath the 5971-160, must also be used. Failure to use adequate
support angles will result in equipment damage.
Take care when selecting a rack that it has enough depth to completely house the Reversal
Switch and DC Supply. The RC-351930 Bench Height Rack offered by GMW has an internal
depth of 762mm (30”). Typical installations would put the DC Supply at the bottom of the rack,
with the Reversal Switch just above, thus keeping the center of gravity as low as possible in the
rack. Other instrumentation may then be installed in to the upper sections of the rack.
Note:
Telco style racks are NOT appropriate for the Reversal Switch and DC Supply.
