SPS 4001B
ELECTRICAL
CONNECTIONS
2-4
All wiring must conform to local and national codes. Use the following
procedure to connect an SPS 4001B to an Oxymitter 4000.
Disconnect and lock out power before connecting the unit to the power supply. Failure to
lock out power could result in serious injury or death.
Install all protective equipment covers and safety ground leads after installation. Failure to
install covers and ground leads could result in serious injury or death.
To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation
of this equipment, connection to the main electrical power supply must be made through a
circuit breaker (min 10 A) in close proximity and marked for this equipment which will
disconnect all current-carrying conductors during a fault situation. This circuit breaker
should also include a mechanically operated isolating switch. If not, then another external
means of disconnecting the supply from the equipment should be located close by. Circuit
breakers or switches must comply with recognized standards such as IEC 947.
NOTE
Ensure the Oxymitter 4000 is set up to handshake with the sequencer by
configuring the logic I/O to mode 8. Refer to the Oxymitter 4000 Oxygen
Transmitter Instruction Manual for more information.
NOTE
To maintain proper earth grounding, ensure a positive connection exists
between the ground lug and earth. Install this wire or ground lug first.
1. Loosen the SPS 4001B cover screws and open the cover.
2. Route the line voltage cable into the enclosure through the rear cable
grip. Ensure adequate wire length to connect the line voltage leads per
Figure 2-2, then tighten the cable grip nut.
3. Connect the incoming 90 to 250 VAC ±10%, 50/60 Hz line voltage leads
to the terminal strip and ground lug as indicated in Figure 2-2.
4. Route the signal wiring cable through the front cable grip. Ensure
adequate wire length to connect all signal wires per Figure 2-2, then
tighten the cable grip nut. Use shielded twisted pair wiring. Terminate
the shield at the SPS 4001B.
