Electrical Connection
CAUTION
The power cord and ac
transformer have a 3-wire
grounding-type plug with a
grounding pin. This is a safety
feature. Grounding of the unit is
vital to ensure safe operation.
Do not defeat the purpose of the
grounding plug by modifying it
or by using an adapter.
Prior to installation, use an outlet
tester or voltmeter to check the
ac receptacle for earth ground. If
the power source does not
provide a ground connection,
consult an electrician to
determine another method of
grounding the unit before
proceeding with the installation.
To power-up the DSU:
"
Procedure
1. Use a non-switched, 3-prong grounded ac wall
outlet capable of supplying the specified voltage
and current.
2. Label the circuit breaker that protects the wall
outlet and be sure it is set to ON.
3. At the rear of the DSU ( Figure 2-3 ), insert the
small end of the power cable into the power
receptacle.
If you have a table-top ac transformer, connect
the 3-prong plug to the ac outlet. If you have a
wall-mount ac transformer, connect the
ac transformer to the ac outlet.
CAUTION
Only use the power transformer
designed for the Model 3610
DSU. Using other transformers
may result in personal injury or
damage to the equipment.
The unit performs a power-up routine.
4. Reinstall the factory configuration options (use the
FacT configuration for a tributary or FacC for a
control).
5. Make any desired configuration changes in the
DSU, Diag (DSU, DBM, and Gen), DBM, Gen,
Bckup, and LPDA-2 option sets.
