2-3 HEATER POWER SUPPLY INSTALLATION

The Rosemount encode sheets (Prod-

uct Ordering Matrix) allow a customer

to order either the hazardous area ver-

sion of the HPS 3000 or the non-

hazardous area version. The hazard-

ous area version has the symbol

"EExd" on the apparatus nameplate.

The non-hazardous area version does

not. Ensure that if you have received

the non-hazardous version that you do

not install it in a potentially explosive

atmosphere. This also applies to the

hazardous/non-hazardous version of

the IFT 3000.

Before HPS installation, consult Safety

Data Sheet 1M03243.

a. Mechanical Installation

The outline drawing of the CENELEC ap-

proved heater power supply enclosure in

Figure 2-12, shows mounting centers and

clearances. The CENELEC approved en-

closure is designed to be mounted on a wall

or bulkhead. The heater power supply

should be installed no further than 45 m

(150 ft) from the probe. The heater power

supply must be located in a location free

from significant ambient temperature

changes and electrical noise. Ambient tem-

perature must be between 0° to 60°C (32°

to 140°F).

b. Electrical Connections

1. Electrical connections should be made

as described in the electrical installa-

tion diagram, Figure 2-13. The wiring

terminals are divided into two layers:

the bottom (FROM PROBE) terminals

should be connected first, the top

(FROM ELECTRONICS) terminals

should be connected last (Figure 2-14).

Each terminal strip has a protective

cover which must be removed when

making connections. To remove the

terminal covers, remove two slotted

screws holding cover in place. Always

reinstall terminal covers after making

connections.

2. Power Input: 120, 220 or 240 Vac. For

120 Vac usage, install jumpers JM4

and JM1 and remove JM5 if installed.

For 220 or 240 Vac usage, install

jumper JM5 and remove JM1 and JM4

if installed (see label, Figure 2-15).

If you reconfigure the equipment for a

line voltage other than the one marked

on the serial label and the mains filter

of the power supply then you should

change the marking on the serial label

and the mains filter to state the new

line voltage.

NOTE

Fuse specifications are shown in

Figure 2-14.
