WARNING:
 
  Warnings contain directions that you must follow for your 
 
personal safety. Follow all instructions carefully.
 
Please read carefully and thoroughly the following information before 
 
installing the AccessBuilder 500:
 
Exceptional care must be taken during installation and removal of the unit.
 
If the power supply plug is unsuitable and you have to replace it, you 
 
may find other codings for the respective connections. Connect the 
 
power supply wires from the unit according to the following scheme:
 
Brown wire to the Live (Line) plug terminal which may be marked 
 
with the letter L or colored red.
 
Blue wire to the Neutral plug terminal which may be marked with 
 
the letter N or colored black.
 
Yellow/green wire to the Earth (Ground) plug terminal which may 
 
be marked with the letter E, or the earth symbol or colored 
 
green/yellow. Do not connect the earth wire to any other pin.
 
The safety status of the interconnection port on this equipment are as 
 
follows:
 
Ports identified by the labels VOICE and ISDN = TNV
 
Ports identified by the labels MANAGER, 10BASET, AUI and WAN = SELV
 
TNV (telecoms network voltage) is a circuit which under normal 
 
operating conditions carries telecommunication signals.
 
SELV (safety extra low voltage) is a secondary circuit which is designed 
 
and protected so that under normal and single-fault conditions, the 
 
voltage between any two accessible parts does not exceed a safe value 
 
(42.2 V peak or 60 V DC).
 
Only connect apparatus complying with the relevant interface 
 
requirements to the ports on this unit.
