Installing the Device
2.5.1Connecting High AC/DC Power
PS1 terminals. High voltage wiring is always made to the upper Hi terminal
block and low voltage (24/48 V) wiring is always made to the lower Lo terminal
block.
• Use minimum #16 gage wiring when connecting terminal blocks.
• The maximum wire length between the terminal block and power source must
not exceed 6 m (20 ft) for 24 V power supplies or 18 m (60 ft) for 48 V power
supplies.
• A circuit breaker rated no higher than 20 A must be installed between the device
and the supply mains.
• Whenever possible, use a separate circuit breaker for each power supply.
• For maximum redundancy in a dual power supply configuration, use two
independent power sources.
• A socket outlet/disconnect device must be installed near the device and be easily
accessible.
• Equipment must be installed according to applicable local wiring codes and
standards.
2.5.1 Connecting High AC/DC Power
To connect a high AC/DC power supply to the device, do the following:
DANGER
Electrocution hazard – risk of death, serious personal injury and/or damage to
the device
Make sure the supplied cover is always installed over high voltage screw-type
terminal blocks.
NOTICE
Electrical hazard – risk of damage to equipment
Do not connect AC power cables to a DC power supply terminal block. Damage to
the power supply may occur.
Note
The screw-type terminal block is installed using Phillips screws and compression
plates, allowing either bare wire connections or crimped terminal lugs. Use #6 size
ring lugs for secure, reliable screws, which must be removed to make connections.
