Electrical Connections

Electrical Shock Hazard – All input and output wiring should be installed in such a manner that access to bare copper is
prohibited during normal operation .
ƒ IcoTek KEL-DPZ 24/26 and KEL-ER 24/10 multi-membrane cable entry plates are provided on the bottom and right
side of the enclosure for up to 26 cables with 5 - 10.2mm cable diameter.
ƒ On the left side of the enclosure, cable entries are provided for the ethernet connection.
ƒ Figure 9 (board view) and Figure 10 (schematic view) show the power connections on the board.
Power Connection
The Sample Sequencer 6 uses a universal power supply that accepts an input voltage range of 85-305 VAC and
frequency of 47-440 Hz. A power supply lead of 12-24 AWG (4-0.25 mm2) copper wire is recommended.
ƒ Connect the sample sequencer to an electrical outlet or outlet strip with surge suppression and filtering. Using this
method, the plug serves as the disconnect device.
ƒ A 12-24 AWG, 60°C, VW-1, 600V, type SJT cord is recommended for non-detachable connections.
ƒ For permanent connections, use a flexible SOW cable or better. Sizing must be in accordance to the CEC.
ƒ A suitable external over-current protection device such as a fuse (Class CC, 2A, Time delay) or circuit breaker (C trip
curve, 2 A) is recommended for both the hot (L) and neutral (N) leads.
The mains and output terminal are rated within the following condition:
ƒ Mains terminals rated up to 300V, 17.5A, 12-30 AWG, PA insulating material, Inflammability class V0, Type: Plug, 8
position, and screw connection.
ƒ Output terminals rated up to 300V, 17.5A, 12-30 AWG, PA insulating material, Inflammability class V0, Type: Plug, 8
position, and screw connection.
For permanently connected installations:
ƒ A switch or circuit breaker shall be included in the building installation.
ƒ It shall be in close proximity to the equipment and within easy reach of the operator.
ƒ It shall be marked as the disconnecting device for the equipment.
The cord and plug shall comply with the following standards:
