Caution: Check probe terminal connection carefully to be certain

lug will not short to packing gland or interfere with assem-

bly of amplifier housing to probe.

19. Proceed to Section 2.7, Wiring.

2.6

Electrostatic Discharge (ESD)

Handling Procedure

Magnetrol’s electronic instruments are manufactured to

the highest quality standards. These instruments utilize

electronic components which may be damaged by static

electricity present in most work environments. The

following steps are recommended to reduce the risk of

component failure due to electrostatic discharge:

1. Ship and store circuit boards in anti-static bags. If an

anti-static bag is not available, wrap board in aluminum

foil. Do not place boards on foam packing materials.

2. Use a grounding wrist strap when installing and

removing circuit boards. A grounded workstation is

also recommended.

3. Handle printed circuit boards only by the edges. Do not

touch components or connector pins.

4. Ensure that all electrical connections are completely made

and none are partial or floating. Ground all equipment to

a good, earth ground.

2.7

Wiring

2.7.1 Integral Mount Models

Light gauge (16 AWG or 18 AWG) stranded wire should

be used for connection of power and control circuits.

2.7.1.1 Relay Wiring

See Section 2.7.3, Relay Wiring Chart on page 10 for

different relay wiring options.

2.7.1.2 Power Wiring

1. Make sure power source is turned off.

2. Pull power supply wires through conduit connection.

3. Connect AC power to AC(+), AC(–) and GND terminals.

Connect DC power to DC(+) and GND terminals. Refer

to Section 3.4, Terminal Connections on page 21.

4. Dress the wires together neatly and securely with cable ties.

Be certain that adequate clearance exists for replacement of

housing cover.
