4. cable terminal HD1. Removing this shield also gives access to the
blanking plug to allow a suitable conduit or the cable gland to be fitted.
5. If using a conduit for the power cord, remove the blanking plug and install
a suitable conduit in its place. Secure as recommended by the conduit
manufacturer.
6. If using a power cord without a conduit, remove the blanking plug and fit
the 1/2-in. NPT cable gland instead as depicted below. Please note it is
easier to fit the cord through the gland outside of the enclosure then attach
the cable gland to the enclosure.
7. Carefully connect the Live and Neutral cores to the correct HD1 screw
terminals as shown below and also printed on the PCB.
Live HD1-L
Neutral HD1-N
Earth HD1-3
8. Crimp a 6 mm ring terminal (supplied) to the earth core on the power cord
using copper washers. Securely bolt this to the earth termination post with
the lid and PCB earth wires. Tighten the cable gland to secure and seal
the power cord.
9. Reattach the mains head-end shield taking care to avoid pinching the
cables and securely screw down.
10. Feed the shielded composite cable through the metal M16 gland; then
connect the shielded composite cable to the screw terminal HD3 as
printed on the PCB. When completed tighten the cable gland to firmly grip
the shielded cable.
11. Connect a tamper switch to HD2, if necessary.
12. Feed the coax cable through the cable gland and crimp the end with a
BNC connector then connect the coax video cable to the CN1 socket.
13. Use CN2 for additional add-on cards such as the 8-input alarm card or the
Bi-phase card.
14. Crimp or screw telemetry connections to terminal HD4 or HD5 to connect
the MIC camera to the control room.
15. When wiring is complete, apply power and check the all four (4) LEDs are
lit.
• LED1 – 18 VAC power on to camera
• LED2 – 18 VAC power on to camera
• LED4 – Power on for optional heater
• LED5 – Power on for optional heater
16. Re-attach the enclosure lid and screw it down until tight.
17. For installation of the MIC-WKT-KIT, MIC-ALM or MIC-BP-4 Bi-phase card
please refer to the respective manuals.
