Installation Warnings and Prerequisites
Danger!
ELECTRICAL SHOCK HAZARD
To reduce the risk of electrical shock, disconnect power before opening or working on any
power supply unit. Power must be disconnected before replacing any fuse in the MIC PSU.
Power supply units have power supplied whenever the power cord is inserted into the power
source.
MIC PSUs have a separate internal shield covering the power cable input terminal block
(HD1). Only suitably qualified persons should remove this shield and connect the mains power
cable. The shield MUST be re-installed and fully secured before connecting the power.
The power supply cable shall have conductors of a maximum size of 12 AWG.
Branch circuit protection incorporating a 15 A, 2-pole, listed circuit breaker or branch rated
fuses are required. A readily accessible 2-pole disconnect device with a contact separation of
at least 3mm must be incorporated externally to the equipment.
!
Warning!
To meet UL standards and ratings, all external wires (power and I/O cabling) for installation
applications to the device must be routed separately through different permanently earthed
metal conduits (not supplied).
Notice!
Use only UL-listed liquid tight strain reliefs for conduits to the power supply box to ensure
that water cannot enter the box. You must use watertight conduits and fittings to meet NEMA
6P or to maintain IP68 standards.
Notice!
MIC PSU enclosures are not EXD rated and must be replaced with a certified enclosure if
installed within a hazardous area.
!
Caution!
Except for the Earth Link, heater links, and applicable fuses, the MIC PSUs have no user-
adjustable parts. MIC cameras have no user-serviceable parts.
