GLC2300-LG41-24V (UL Registration Model: 2980070-11)

GLC2300-TC41-24V (UL Registration Model: 2980070-12)

Installation Precautions

If the GLC is mounted so as to cool itself naturally, please mount it on a vertical
panel.  Also, insure that the GLC is mounted at least 100 mm away from any other
adjacent structures or machine parts.  If these conditions are not met, the heat gener-
ated by the GLC's internal components may cause it to fail to meet UL standards.

UL1604 - Compliance and Handling Cautions

1. Power and input/output wiring must be in accordance with Class I, Division 2

wiring methods - Article 501-4(b) of the National Electrical Code, NFPA 70

Electrical Code for units installed within Canada.

2. Suitable for use in Class I, Division 2, Groups A, B, C, and D Hazardous Loca-

tions.

3. WARNING: Explosion hazard

- substitution of components may impair com-

pliance to Class I, Division 2.

4. WARNING: Explosion hazard

- when in hazardous locations, turn the power

OFF before replacing or wiring modules.

5. WARNING: Explosion hazard

- confirm that the power supply has been turned

OFF before disconnecting equipment, or
confirm that the location is not subject to the
