Installing the NC-2000 Patient Unit
1. Connect the first 5 wires to terminal CN16, a 5-position screw down block. There are 4
live outputs and a common return for the brown wire (see Figure 14).
Figure 14 NC-4LED connections on terminal CN16
NC-4LED electrical ratings:
•
24 VDC @ 40 mA per LED (total of 160 mA for all 4 LEDs)
Note:
Do not overtighten the screw terminals.
Note:
When calculating the power requirements for the Patient Unit, you must include
the power requirements for the dome lights.
For example, with NC-4LED, the following input currents are drawn by the
Patient Unit (at 24 VDC output):
•
Patient Unit maximum current: 25 mA
•
NC-4LED: 160 mA
In this example, use a power supply rated at 200 mA or more.
Note:
See section 3.8, Power, on page 27 for more information on power connections.
