INSTALLING THE AT30

1.8. MAKING THE DC OUTPUT CONNECTIONS
Follow these steps to connect the battery to the AT30:
1. Size the dc wiring to minimize voltage drop. The acceptable wire size
depends on your installation. As a guideline, the voltage drop should not
exceed 1% of nominal output voltage at full current.
2. Size the dc output wiring per your battery manufacturer's specifications and
local codes for the rating of the batteries and/or load.
3. The AT30 is factory wired to regulate the output voltage at the output
terminals. If the total voltage drop is greater than 1% (e.g., 1.3V for a 130
Vdc system), remote sense wiring is recommended, see Section 1.9.
4. All specific requirements of your facility take precedence over these
instructions.
5. Do not run the external dc power wiring through the same conduit of the
battery charger enclosure as the external ac power wiring.
PROCEDURE
1. Use a dc disconnect switch or circuit breaker between the AT30 and dc bus.
This device should have lockout capability to allow the AT30 to be
disconnected from the dc bus for maintenance.
2. Remove the safety cover (if supplied).
3. Run the dc wiring to terminals TB1(+) and TB1(-) on the I/O panel board in
the enclosure.
4. For your convenience, all AT30 Series battery chargers are supplied with
CU-AL dc output compression lugs. Style-5018 enclosure dc output lugs
accept #14-1/0 AWG wire. Style-5030 and Style-163 enclosure dc output
lugs accept #6 AWG - 350 MCM wire. To make these connections, strip the
insulation 0.5in / 12.7mm on the incoming ac wires and connect the wires to
the appropriate lugs as shown on the next page.
5. Using a flat-head screwdriver, securely tighten the compression screws on
the lugs to 35-50 in-lb / 4.0-5.7 Nm.
6. Reinstall the safety cover (if supplied) after you have made and checked all
connections.
NOTES
1. The dc output terminal hardware fastens other components mounted to the
I/O panel. Be careful not to disconect any other component leads.
2. Always use a proper ground.
3. Use copper or aluminum conductors only.
4. Refer to images on the following page for I/O panel layout.
