2.0 Cabinet Installation
WARNING: Please read this section completely before commencing installation.
Prior to commencing installation of the control panel, ensure that adequate precautions are
taken against static damage to the sensitive electronic components on the control board. You
should discharge any static electricity you may have accumulated by touching a convenient
earthed object, e.g. an unpainted copper radiator pipe. You should repeat the process at
regular intervals during the installation process, especially if you are required to walk over
carpets.
The panel must be powered down before removing or replacing any card or module. Failure
to observe this may cause damage to the loop cards and the motherboard.
When changing any plug-in cards, observe anti-static precautions. Ensure that all power is
removed from the system. Failure to do so may result in damage to the cards or panel.
The panel must be located in a clean, dry position which is not subject to shock or vibration
and at least 2 metres away from pager systems or any other radio transmitting equipment.
The maximum temperature range is 0ºC - 40ºC; maximum humidity is 95%.
This equipment contains dangerous voltages. To prevent electric shock to unqualified
personnel ensure that the door is locked at all times when the panel is left unattended. Do
not leave the key to open the panel door with unqualified personnel. There are no user-
serviceable parts inside.
IMPORTANT NOTES ON BATTERIES:
DANGER: Batteries are electrically live at all times, take great care never to short circuit the
battery terminals.
DANGER: A lithium “coin cell” is fitted to the motherboard PCB. There is a danger of
explosion if this battery is incorrectly replaced. Replace only with same or equivalent type
recommended by the manufacturer. Dispose of used batteries according to the
manufacturer’s instructions. The replacement of this battery must be carried out by trained
service personnel only.
WARNING: Batteries are often heavy, take great care when lifting and transporting
batteries. For weights above 24 kilos, lifting aids should be used.
WARNING: Do not attempt to remove battery lid or tamper with the battery internal
workings. Electrolyte is a highly corrosive substance, and presents significant danger to
yourself and to anything else it touches. In case of accidental skin or eye contact, flush the
affected area with plenty of clean, fresh water and seek immediate medical attention
.
VRLA batteries are “low maintenance” requiring no electrolyte top-up or measurement of
specific gravity.
WARNING: If required, clean the case with a cloth that has been soaked or dampened with
distilled water. Do not
use organic solvents (such as petrol, paint thinner, benzene or mineral
spirits) and other materials can substantially weaken the case.
WARNING: Avoid operating temperatures outside the range of -15
°
C/5
°
F to +50°C/122°F
for float/standby applications.
