2. INSTALLATION PROCEDURE EO18-13005
2.1 CONECTING THE TRST-A10 TO THE POS TERMINAL
2. INSTALLATION PROCEDURE
WARNING!
1. Turn the POS terminal OFF before connecting the TRST-A10 printer.
2. Plug the TRST-A10 power cord into the AC outlet on the wall for power supply. Do not obtain the
AC power from the AC outlet of the POS terminal such as ST-A10, ST-7000, etc., because the
rush current at the TRST-A10 power on may exceed the rating of the power switch of the POS
terminal. Failure to do this may shorten the life of the power switch of the POS terminal.
2.1 CONNECTING THE TRST-A10 TO THE POS TERMINAL
CAUTION!
1. Use a locally purchased power cord which meets the standard.
2. Firmly plug the AC adapter cable and the power cord.
1) Turn the printer power OFF.
2) Insert the power cord into the AC inlet.

2.2 CONNECTING THE DRAWER
2.2 CONNECTING THE DRAWER
WARNING!
1. The solenoid included in the drawer to be connected should have the minimum of 36 ohm
resistance. Under-specified solenoid may cause a machine failure.
2. The output current of the drawer should not exceed 0.8A, as there is a risk of a machine
failure.
3. The drawer interface connector is exclusively for connecting a drawer. Do not connect a
phone line or any other cables than the specified drawer cable. Doing so may cause a
failure of the phone line and the printer.
Connectable drawers must meet the following conditions.
• The drawer which includes the Drawer Drive Circuit (DC 24V specification).
• The drawer which has 6-pin modular connector.
