In-Rush current
When the equipment is turned on, a large in-rush current flows as the capacitor is
instantaneously charged and the transformer is excited. When any equipment is turned on, this
should not cause any voltage fluctuation that could adversely affect other equipment. Do not turn
on all equipment at the same time. Start equipment one by one.
Power may be switched to backup or AC line power if in-rush current activates the overload
protection circuit on power-up. After such an overload, select an uninterruptible power unit, with
automatic-recovery.

Cabling
Observe the following when cabling the power unit to the system equipment:
• Protect signal cables from induced noise.
• Protect signal cables from induced noise from high-voltage power lines.
• Separate the system power supply from other equipment power supplies using a power
distribution board.
• Provide a dedicated breaker for each power supply.
• Label the breakers with the name of the connected equipment.
• Install the breakers where they can be easily operated.
• The breaker, must not interrupt connection by wiring to protective grounding system.
• Install power supply cables and high-voltage power lines in metallic conduits as much as
possible.
• Use shielded cables if metallic conduits cannot be provided.
