operating or maintenance instructions.
The Lightning bolt triangle is used to alert the user
to the risk of electric shock.
SAFETY
1. It is important to read these instructions, and to follow them.
2. Keep this instruction manual in an accessible place.
3. Do not install this equipment near any heat sources such as radiators, heating
vents or other apparatus that produces heat.
4. WARNING: THIS APPARATUS MUST BE EARTHED.
5. The HLS-2B is designed to be permanently connected apparatus and must be
installed with all applicable installation regulations. A readily accessible all pole
mains disconnect device shall be incorporated in the building installation power
wiring.
6. The apparatus should not be exposed to dripping or splashing and should have
no objects used for storing liquids placed upon it.
7. Mount the HLS-2B with the wiring entering from the side of the unit. Position
cables in a neat manner, and tighten the P-Clips to ensure the cables are fully
restrained. The cables should be positioned in such a manner that any liquid
spilled on to them will not run into the unit. Cable access is via 3 cable entry
points on the end of the unit. If the installation cables do not fill the entry hole or
any hole isn’t used then the hole should be masked such that any gaps are
<4mm wide.
8. Do not mount the unit with the battery terminals facing downwards.
9. Refer all servicing and installation to qualified personnel.
WARNING: Isolate AC power externally before servicing or replacing fuses.
10.The amplifier generates some heat during normal operation and needs
adequate ventilation. It should not be fitted in a fully enclosed space.
11.The battery should not be exposed to heat, sunshine or fire.
The
has been designed as a high quality stand-alone induction loop driver
for use in small to medium size lifts, although the rugged construction may be
suited to other industrial applications.
The unit is designed to drive a loop constructed out of custom built metal bars,
which is a very low impedance. Ordinary wire can sometimes be used if it can be
installed inside the lift car, but care must be taken to ensure the loop satisfies the
unit’s load requirements.
All versions have:
#
two separate audio inputs,
#
230V or 115V AC power supply (factory set option)
#
transformer coupled loop output.
The standard unit has two low-Z speaker line level input.
All connections (except the ‘Protective Earth Terminal’) are via vibration-resistant
cage clamp terminals which are quick and easy to connect.
