Installing the Rack Mount

Use screws provided with rack system. Refer to the rack user documentation for instructions.

Installer should ensure that all building codes are followed when connecting the power supplies to an AC power source.

Secure mounting brackets to both sides of top tray with four M5 screws (two on each side). For 4-Slot cradles, position the flange for horizontal installation. For 4-Slot Battery Chargers, position the flange for 25° installation.

Flange Horizontal Position (4-Slot Cradles)

1	Flange
2	Fifth screw hole

Flange 25° Position (4-Slot Battery Chargers)

1	Top screw hole
2	Flange

Install the mounting bracket with 4-Slot cradle at a maximum height of four feet from the ground. Install the mounting bracket with 4-Slot Battery Charger at a maximum height of three feet from the ground.

Distance between two horizontal mounted brackets should be at least 14” apart (from top of one flange to the top of the next flange).

Distance between a horizontal mounted bracket and a 25° mounted bracket should be at least 16.25” apart (from top of one flange to the top of the next flange).

There should be enough clearance (2.75”) between the top of the device and the bottom of the mounting bracket above.

Install two rack system screws for top of mounting brackets. The screw heads should protrude halfway from the rail.

1	Rack screw
2	Rack screw

Align the mounting bracket’s top mounting key holes with the screws.

Place the brackets on the screws.
