USING THE PST SYSTEM
BEFORE POWER ON
–
A Check List
It is very important that you check the following operational points:
Ventilation
This terminal must NOT be operated in an environment with
restricted ventilation. There must be at least 25 mm air clearance around any
top or side ventilation holes with a free flow of air around the unit at ALL
times for the installation.
Operating Environment
The equipment must not be operated or stored in extremes of both
temperature and humidity/moisture.
(Operating range 0
°
C to + 35
°
C and up to 80% relative humidity –
non condensing max. wet bulb 26
°
C)
Power Supply
The operating voltage of the power supply should be checked to
confirm that it is set within the range of the local power supply. The power
cable, the power outlet and any power fusing arrangements must conform to
local safety regulations.

definitely observe the alerts in beginning of this manual. If the equipment is to
be powered off for more than few days, please always disconnect the battery
from the system. Reconnect it and turn on the system to recharge the battery
for 1 ~ 2 hours every 3 months for temperature lower than 30
°
C. Recharge for
1 ~ 2 hours every month for temperature over 30

battery condition) power failure if the power management option is installed.

there is a built in utility Power Manager that will indicate the UPS battery
status of the battery. When an installed UPS battery is found to be disabled,
please replace the used up UPS battery at power off as soon as possible.
