General Installation
Internal Modem
When the TopKAT system is equipped with the optional internal modem, the Port 3
communication is routed through the modem in place of being wired at the DC Junction box.
Jumper K2 should be removed. Refer to
for the location of
jumpers K1 and K2. The phone line for the internal modem can be installed in the DC conduit.
If you are installing the phone line in a DC conduit, the cable must be two twisted-pair
shielded cables as specified in
on
and the shield
drain wire must be connected to the system AC ground. Check with your local phone company
for proper installation of the phone line.
If you order your TopKAT system with an optional internal modem, the modem is mounted
within the TopKAT system at the factory and power for the modem is supplied by the
TopKAT system. The 2400 baud modem is designed for 300, 1200, or 2400 baud, full duplex,
asynchronous communication. The 33600 baud modem is designed for 1200, 2400, or 9600
baud, full duplex, asynchronous communication. This modem meets or exceeds the direct
connection registration requirements of the FCC rules. The modem will connect directly
through a phone line supplied by the phone company. The customer is required to order this
phone line and have it installed.
To order this equipment from the phone company, specify:
1
The registration number of 6BHUSA-24793-DT-E.
2
The data transmission rate of 300 baud, 1200 baud, 2400 baud, or 9600 baud.
3
The Bell equivalent of 103J/212A.
Power Conditioner
When used, a UL-listed power conditioner helps provide clean power to the TopKAT system.
Poor power conditions are a key cause to system malfunction or failure. The power
conditioner provides transient and common mode protection for the TopKAT system,
although it cannot totally compensate for extremely poor power conditions. The power
conditioner must be located in an area protected from direct contact with the weather
(typically near the system circuit breakers) and should be no further than 50 feet from the
TopKAT system for optimum protection. It must not be used over a hazardous location.
When used with a TopKAT system that is installed on a 9800 or ASTRA, the Micro Feed line
from the pump/dispenser is routed through the power conditioner and then to the breaker. With
a mechanical installation, the TopKAT system is directly connected to the power conditioner
and then to the breaker. The power conditioner is designed for an operating temperature range
of -20
°
C to 48
°
C.
