WARNING

Risk of serious personal injury or damage to equipment and property! Always

observe the following:

• Use an appropriately rated over-current protection device in line with the

main battery connections to the power distribution unit

• Use an appropriately rated disconnect switch or circuit breaker in line with

the dc inputs to enable installation and service of the power distribution unit

with the dc source disconnected

• Shut off or disconnect all dc power sources before connecting or

disconnecting wiring

• Use wire and connectors rated for the maximum load current and size of

fuse or circuit breaker, and keep cable lengths as short as practical

• Carefully observe wiring polarity when making input and output connections

• Securely tighten all connections

• Do not attempt to service any internal parts. Refer all product service to an

authorized ICT Ltd. service facility

CAUTION

Risk of personal injury or damage to equipment! Always observe the following:

• Fuses may be HOT to touch. Disconnect power and allow to cool before

removing or replacing

• Wiring terminals may be HOT to touch. Disconnect power and allow to cool

before disconnecting load wires

• Install unit in a restricted access location (such as an equipment rack) to limit

unintentional contact with terminals and wiring. Keep sources of moisture

away from unit

• Do not block air inlet or outlet openings in the power distribution unit sides

NOTE:

Due to the fuse detection circuitry internal to the power distribution unit, it

may be possible to measure a voltage on the output terminal(s) even if that

output’s fuse is open (with no load connected). This is normal operation. The

detection circuitry is a high-impedance circuit, and while a voltage may be

present on the output terminal, it is purely a signal voltage and does not

support loading. Any load device connected to the output will immediately

pull this voltage to zero volts.
