(1) Carefully consider the leakage current when a leakage
circuit breaker is installed on the input side.
The maximum leakage current of the UPS is 3mA.
(2) Keep the UPS at least 1 m (about 40 inches) away from
CRT displays. Other devices which may be sensitive to
magnetic flux should be kept away from the UPS,
as it emits a slight amount of magnetic flux.
(3) The UPS employs a fan for forced-air cooling. Provide a clearance specified in §6.2 “Installation
Space Check” at the front and back of the UPS to permit free airflow at the air intake and exhaust
vents.
(4) When the AC input power is single-wire grounded, always connect the ground phase to the S
terminal (phase) side on the UPS.
(5) As far as possible, do not ground the output (load) side. If you must make a single-wire grounded
connection, always connect the ground phase to the V terminal (phase) side on the UPS. (This is to
prevent short-circuiting by the ground.)

(1) Never short-circuit the output terminals.
Doing so causes protective functions to activate or fuses to blow, preventing output.
(2) Unsuitable load devices
Do not connect laser printers, plain paper fax machines, copy machines, or overhead projectors as
load devices. Such devices typically include heating elements that draw high current. This may cause
an overload that could prevent battery backup operation when an outage occurs, and could damage
the UPS.
(3) Power supply environment
If the UPS is used in an environment subject to long and frequent power outages (more than once a
week), the batteries may not receive sufficient charge, which could result in foreshortened battery
life and premature battery failure
(4) If the UPS is not operated for a long period, the batteries may require recharging. If the batteries in
the UPS are left uncharged, their service life will be greatly foreshortened. Recharge (refresh charge)
in accordance with the UPS storage environment as shown in the table below.
Storage Temperature

Operation
25°C
Once every 6 months At least 20 hours
30°C
Once every 4 months At least 20 hours
40°C
Once every 2 months At least 20 hours
(5) Insulation testing
Before testing indoor wiring insulation, shut down the UPS and disconnect the input and output
cables. Conducting an insulation test with the UPS connected may damage electronic components
such as the built-in arrester.
(6) Rack support rails (not supplied) are required to mount the UPS on a rack. For details, contact your
supplier or Sanyo Denki representative.
