Safety precaution for Maintenance and Troubleshooting

WARNING

Do not disconnect

while circuit is live

unless location is known to be nonhazardous.

DON’T

Live part of electric circuit or a high temperature department can cause

explosion

.

Do not modify or disassemble

the enclosure.

DON’T

Strength degradation and defects of enclosure can cause

explosion

.

Do not use parts of other products

.

DON’T

Protective performance degradation for hazardous location can cause

explosion

.

Do not live circuits

While assembly of all components is not over.

DON’T

Protective performance degradation for hazardous location can cause

explosion

.

Install per the National Electrical Code for the US (NEC, ANSI/NFPA 70) and the
Canadian Electrical code for Canada (CEC, CAN/CSA-C22.1) and the drawing
Appendix 1.

DO

Unsuitable conduit connections for hazardous location can cause

explosion

.

CAUTION

Do not conduct wiring work when
power is applied.

Do not touch the GF630/LF600F,
GF630/LF610F and GF632 main body
when high temperature fluid is being
measured.

DON’T

Wiring while power is applied
can cause electric shock.

DON’T

The fluid raises the main body
temperature and can cause burns.
