Installing the Surveillance cabinet
Pre-installation checklist
1.
Make sure that you have the correct camera and accessories for the installation in your
environment.
2.
Determine the location and distance for the unit based on its voltage and current
consumption. Prepare the wires and connections that are necessary to connect your
camera.
3.
You can route the main power supply through an intermediate unit (type PA1 or PA2)
before connecting the power to a PA0 type unit. Refer to Cable and wire standards for
wiring information and distances. See also Routing power through intermediate unit, page
14.
4.
Use only UL listed liquid tight strain reliefs for conduits to the unit to ensure that water
cannot enter the unit. Use water tight conduits and fittings to meet NEMA 4 standards.
!
Caution!
Select a rigid mounting location to prevent too much vibration to the camera.
!
Warning!
Power and I/O cabling must be routed separately inside different permanently earthed metal
conduits.
!
Warning!
Install external interconnecting cables in accordance to NEC, ANSI/NFPA70 (for US
