Connecting Power
Once you have read and understand the requirements on
the previous page, follow these steps to connect power to
the TracNet system.
1.
Disconnect vessel power and be sure the vessel is
properly grounded in accordance with marine
standards.
2.
Connect the supplied ground wire from the ground
stud on the rear panel of the BDU to ship’s common
ground (see Figure 27).
3.
Connect the supplied AC power cord to the BDU.
4.
Plug the BDU power cord into the vessel’s 100-240
VAC supply.
Note:
Consider installing an uninterruptible power supply
(UPS) to avoid service interruptions during power outages
and transitions to/from shore power.
5.
Check for proper grounding by using a multimeter to
measure the AC and DC voltages between the ground
stud on the rear of the BDU and ship’s ground. The
measured voltage should be less than
2 VAC and 2 VDC.
A higher voltage indicates a
dangerous floating ground condition.
6.
Repeat the previous step with the BDU powered on,
looking for the same measured result.

WARNING
Failure to ground the BDU properly to ship’s
ground will cause an unsafe floating ground
condition, risking damage to the antenna
and electric shock, potentially resulting in
DEATH.
In a floating ground condition, the
difference between the equipment's chassis
ground and the vessel’s ground can measure
well over 100 volts, when it normally should
not exceed 2 volts. Therefore, always measure
the difference in potential between chassis
ground and ship’s ground to make certain that
there is no dangerous floating ground
condition, even if the ground pin of the vessel’s
AC power plug appears to be intact.
WARNING
If you measure 2 volts or greater between
the ground stud on the rear of the BDU and
ship’s ground, notify the ship’s electrician
or authorized vessel representative
immediately. This is a dangerous condition.
Do not touch the BDU rear panel or connect
anything to it until the problem is fixed.
