TRAPS
For this section, refer to the Switches and Straps portion of
the Installation section of the TL1 Pointmaster practice.
Ensure that the proper cards are also inserted into the Dantel
and are in the correct slots.
Take all ESD precautions appropriate:
♦
Install or remove modules from the shelf only when the
power is off. If you install a module in the shelf with the
power on, the internal circuitry may suffer damage and the
product warranty will be void.
♦
Remove and install circuit boards only in a static-safe envi-
ronment (use antistatic wrist straps, smocks, footwear, etc.).
♦
Keep circuit boards in their antistatic bags when they are not
in use.
♦
Do not ship or store circuit boards near strong electrostatic,
electromagnetic, magnetic, or radioactive fields.
♦

safety precautions, refer to Bellcore

Power Supply Card
1.
On the Power Supply Module, set strap J7 across pins 1 and 2.
2.
On the RS-232 subassembly (located on the Power Supply card), set
the strap X1 across pins 2 and 3. This will be the same as the ON
position indicated on the card, and sets the DCD active.
3.
On the same RS-232 subassembly, set strap X2 across pins 2 and 3.
This sets the CTS active.
4.
Power Supply module set-up complete. Continue with CPU Mod-
ule.
CPU Module
5.
On the CPU Module, set the strap J3 across pins 2 and 3. This
enables the battery backup.
6.
CPU module set-up complete. Continue with power connections.
Power Connection
7.
Prior to connecting power, verify the polarity and wiring. Refer to
the Wiring portion of the Installation section of the TL1
Pointmaster practice. Verify:
♦
-48VDC connected to screw position 1
♦
Battery return connected to screw position 3 on the front of
the Dantel unit (next to the reset button)
♦
Frame ground connected to the top of the Dantel chassis
(location is marked)
