3.7 Installation Instructions
To install the power supply, follow these steps:
1. Select the mounting position of the MIC PSU so that the PSU cannot be interfered with
either intentionally or accidentally. Bosch recommends using a lockable cabinet.
2. Loosen the four (4) captive Phillips head screws on the top of the lid of the power supply
enclosure (item 11, Figure 3.1). Lift the lid and set it upside down next to the enclosure.
CAUTION!
Installation must be made by qualified personnel and conform to ANSI/NFPA 70 (the National
Electrical Code
®
(NEC)), Canadian Electrical Code, Part I (also called CE Code or CSA C22.1),
and all applicable local codes. Bosch Security Systems, Inc. accepts no liability for any
damages or losses caused by incorrect or improper installation.
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 is 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 for installation applications must be
routed through a permanently earthed metal conduit.
CAUTION!
– Do not connect MIC IR units to a MIC PSU with the heater option enabled as this can
result in damage to the cameras. Ensure that an IR power supply is used with a MIC IR
camera unit. Heaters are available for MIC612 cameras only.
– Except for the Earth Link, heater links (MIC612), and applicable fuse, the MIC PSUs have
no user-adjustable parts. MIC cameras have no user-serviceable parts.
– Bosch recommends using an uninterruptible power supply (UPS) in connection with a
MIC camera/PSU installation.
– MIC PSU enclosures are not EXD rated and must be replaced with a certified enclosure if
installed within a hazardous area.
NOTICE!
To maintain the IP (protection) rating of the power supply enclosure, install only listed or
recognized conduit hubs or fittings with the same environmental rating as the enclosure in
compliance with the installation instruction of the hub or fitting.
