Important Safety Instructions
Damage requiring service
– Unplug the devices from the main AC power source and refer
servicing to qualified service personnel whenever any damage to the device has occurred,
such as:
- the power supply cable is damaged;
- an object has fallen on the device;
- the device has been dropped, or its enclosure has been damaged;
- the device does not operate normally when the user follows the operating instructions
correctly.
Electrostatic-sensitive device -
Use proper CMOS/MOS-FET handling precautions to avoid
electrostatic discharge. NOTE: Wear required grounded wrist straps and observe proper ESD
safety precautions when handling the electrostatic-sensitive printed circuit boards.
Grounding:
- Connect outdoor equipment to the unit's inputs only after this unit has had its ground
terminal connected properly to a ground source.
- Disconnect the unit's input connectors from outdoor equipment before disconnecting the
grounding terminal.
- Follow proper safety precautions such as grounding for any outdoor device connected to this
unit.
U.S.A. models only -
Section 810
of the
National Electrical Code, ANSI/NFPA No.70
, provides
information regarding proper grounding of the mount and supporting structure, size of
grounding conductors, location of discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
Installation location
- The unit is intended only for installation in a Restricted Access Location.
Outdoor signals -
The installation for outdoor signals, especially regarding clearance from
power and lightning conductors and transient protection, must be in accordance with
NEC725
and
NEC800 (CEC Rule 16-224
and
CEC Section 60)
.
Overvoltage
– Installation category (also called Overvoltage Category) specifies the level of
mains voltage surges that the equipment will be subjected to. The category depends upon the
location of the equipment, and on any external surge protection provided. Equipment in an
industrial environment, directly connected to major feeders/short branch circuits, is subjected
to Installation Category III. If this is the case, a reduction to Installation Category II is required.
This can be achieved by use of an isolating transformer with an earthed screen between
primary and secondary, or by fitting listed Surge Protective Devices (SPDs) from live to neutral
and from neutral to earth. Listed SPDs shall be designed for repeated limiting of transient
voltage surges, suitable rated for operating voltage and designated as follows:
- Type 2 (Permanently connected SPDs intended for installation on the load side of the service
equipment overcurrent device)
- Nominal Discharge Current (In) 20 kA min.
For example: FERRAZ SHAWMUT, STT2240SPG-CN, STT2BL240SPG-CN rated 120/240 VAC,
(In=20 kA)
Power disconnect
- An appropriate disconnect device shall be provided external to the
equipment.
Surge suppression
- Use proper surge suppression on your network video, power, audio, and
alarm cables.
