Caution:
NEVER look into optical fibres or optical output connections. Always use optical
power meters to determine operation or signal level.
Caution:
Testing may leave capacitors charged to dangerous voltage levels. Discharge
capacitors by rediucing test voltages to zero before disconnecting test leads.
Caution:
Before cleaning the equipment, ensure that no connections are energised. Use a
lint free cloth dampened with clean water.
Note:
Contact fingers of test plugs are normally protected by petroleum jelly, which should not be removed.
3.3 UL/CSA/CUL REQUIREMENTS
The information in this section is applicable only to equipment carrying UL/CSA/CUL markings.
Caution:
Equipment intended for rack or panel mounting is for use on a flat surface of a
Type 1 enclosure, as defined by Underwriters Laboratories (UL).
Caution:
To maintain compliance with UL and CSA/CUL, install the equipment using UL/
CSA-recognised parts for: cables, protective fuses, fuse holders and circuit
breakers, insulation crimp terminals, and replacement internal batteries.
3.4 FUSING REQUIREMENTS
Caution:
Where UL/CSA listing of the equipment is required for external fuse protection, a
UL or CSA Listed fuse must be used for the auxiliary supply. The listed
protective fuse type is: Class J time delay fuse, with a maximum current rating
of 15 A and a minimum DC rating of 250 V dc (for example type AJT15).
