Connecting Power
The GR05 has a built in mains operated power supply unit. This converts and
conditions the mains voltage to the DC voltages required to power the circuits.
An additional DC power input is available on the rear panel expander/remote
connector. This lets you connect a backup power supply such as a battery unit
which automatically takes over in the event of a mains power failure. Check the
requirements of the installation regarding the specification of safety and power
systems.
Refer to the SAFETY WARNING ! and PRECAUTIONS on page 3 of this
guide. Also read the safety warnings printed on the rear of the unit.
Mains Voltage Setting
The factory set voltage setting is marked in this box. Do
not switch the unit on if this is not the same as your
local mains voltage. In this event please refer to your
dealer or service agent.
Mains Input Cable
The GR05 is supplied with a separate 1.8 metre long IEC
mains cable with fitted moulded mains plug suitable for
the supply in your area. If this is not the case please
refer to your dealer or service agent.
Mains Fuse
This fuse provides protection should the power unit fail.
Always replace this fuse with the correct type and
rating as specified on the rear panel.
Mains On/off Switch
This switch is rear panel mounted to prevent accidental
or illegal user operation. Press to switch the unit on or
off.
Battery Backup Input
The expander/remote connector includes 3 pins for
connection to an external dual rail DC power supply unit
or battery backup system. Input voltage range is +/- 12
to 15V DC:
pin13 = +V, pin12 = -V, pin25 = 0V
Should the mains power supply fail or be switched off
the backup supply will automatically take over. There is
no interruption to the operation of the unit.
Power Indicator
The front panel power indicator LED displays four power
conditions:
Off = No power applied
Green = Mains power on only
Red = Backup power on only
Yellow = Mains and backup power on
Earthing
Do not remove the earth connection from the mains
cable.
