Warning - dangerous voltages - the TimeLord
master clock must be disconnected from the mains
supply prior to removing the top cover.
Power Supply Connection
The TimeLord family of master clocks are fitted with universal
power supplies suitable for 110v - 240v ac operation. The
desktop version may be supplied for 230v AC, 110vAC or 12v DC
operation. Please specify appropriate end user location at
time of order to enable correct power adapter or connector
type to be supplied.
PSU order codes:
.AU - Australian style, 240v 50Hz ac.
.EU - European style, 230v 50Hz ac.
.UK - UK style, 230v 50Hz ac.
.US - US style, 110v 60Hz ac.
The TimeLord rackmount master clock is supplied with an IEC
style mains lead.
The TimeLord-Lite/T is supplied with an external 12v DC PSU.
If an alternative PSU is to be used, it should have a rating of
greater than 0.4A at 12v DC.
The master clock must be connected to the appropriate supply
after first verifying the correct voltage by reference to the
supply voltage label fixed to the rear of the clock (rackmount
versions) or on the external power supply (desktop).
A connection to the earth line must be made to ensure safe
operation and ensure compliance with EMC regulations.
To ensure conformance with EN60950:
(A) For installations where the TimeLord master clock
is to be permanently connected into the mains
power circuit, a readily accessible disconnect device
should be incorporated in the fixed wiring.
(B) For installations where the TimeLord master clock
is to be plugged into the mains power circuit, a
socketed outlet should be installed near the
equipment and should be easily accessible.
All installation work should be performed in accordance
with the Sixteenth Edition of the IEE Wiring Regulations.
Battery backup.
Expandable TimeLords are fitted with a Lithium battery which will
maintain the internal time count for a period normally in excess of
1 year if the mains supply is interrupted.
The TimeLord-Lite is fitted with an automatically recharging battery
which will, when fully charged, maintain the internal time
count for a period in excess of 50 hours if the mains supply is
interrupted.
Fuses and Output protection.
The TimeLord circuit board makes use of advanced automatically
resettable fuse technology so that it is protected under fault
conditions.
The universal power supply within the TimeLord uses a
20mm fuse rated at 2 Amps 250V. Please note that this fuse is
not a user serviceable part.
External Connections
The external connections located on the rear of the TimeLord
provide the following inputs and outputs:
