INSTALLATION
Caution:
The 231HC Amplifier’s mass is approximately 47 kg (100 lbs). In many cases, the
Amplifier 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 shipping crate by removing the spring clips along the crate top panel.
2. Cut the straps that secure the amplifier into the shipping crate.
3. Using two people, carefully lift the amplifier clear of the shipping crate. Handles
have been provided on the front as well as the rear of the amplifier case for this.
Always lift the amplifier by all four handles.
4. Inspect the amplifier 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 assessment of the damage must be made. If no
damage is found, proceed with the installation.
5. Unpack any other system components as per their instruction manuals.
3.2 - Rack Mounting
When rack mounting the 231HC Amplifier it is important to note that the vertical mounting
flanges alone are not strong enough to support the weight of the amplifier, and support angles on
each side, beneath the 231HC, 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 Amplifier and
DC Supply. The RC-351930 Bench Height Rack offered by GMW has an internal depth of
762mm. Typical installations would put the DC Supply at the bottom of the rack, with the
Amplifier 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 Amplifier and DC Supply.
