SAFETY
1.0 Installation.
Unless otherwise stated TSL equipment may be installed at any angle or position within an operating
temperature range of 5° ~ 30° C .
The RJ45 connector is for use only with an Ethernet 10/100 system.
All TSL equipment conforms to the EC Low Voltage Directive:
EC Low Voltage Directive (73/23/EEC)(OJ L76 26.3.73)(LVD).
Amendment: (93/68/EEC) (OJ L220 30.8.93).
CAUTION:
Always disconnect equipment connected to a powered MDU before performing any maintenance.
Potentially hazardous voltages are present even after the operation or removal of a fuse, unless the front
panel circuit breaker is set to OFF.
Earthing/Grounding
In all cases, the frame of the equipment must be earthed on installation. Connection to an earthed strip
running the length of the frame is ideal.
The earth pin on the mains inlet connector is connected to the metal frame of the equipment, to 0 volts on the
internal DC PSU and to signal ground, unless otherwise stated. All metal panels are bonded together. Rack
mounted equipment must be earthed (grounded).
Mounting
Careful consideration of the equipment location and mounting in racks must be made. In particular,
consideration must be given to the stability of free-standing racks by mounting heavy equipment low in the
rack. The rear of the unit should be supported in the rack.
Power
This equipment is designed for installation in any position in a rack.
Consideration must be given to the supply circuit loading and switch on/fault surges that will affect overcurrent
protection trips and switches etc.
Check that the fuse rating is correct for the local power (mains) supply. Replacement fuses must be of the
same rating and type for continued protection against fire risk.
The equipment rating is shown on the rear panel.
No power supply cord is provided with this equipment but the inlet connector is.
Do not switch on until all connections are made.
Ventilation
Due consideration for cooling requirements must be given when mounting the equipment. The equipment
contains an internal temperature sensor.
General
If equipment is installed in a closed unit, consideration must be given to providing forced air cooling in order
that the maximum recommended temperature is not exceeded.
