Preparing to Wire the Ex de Increased Safety Models
SHOCK HAZARD
- To avoid electrical shock hazards, do not connect wires when power is applied. Failure to observe this
warning may lead to serious injury or death.
This section has wiring instructions for the three increased safety models:
•
G-SND 24 Vdc
•
G-SND 120 Vac
•
G-SND 240 Vac
Ex de units are supplied with a six-pole, spring-tension clamp style terminal block. The maximum wire gauge is 4.0 mm
(12 AWG). The wire must be rated 85°C or higher. Use only stranded cable to terminate the sounder. The cross-sectional
area of the primary earth (ground) must equal the cross-sectional area of the phase conductor.
Cable termination should be in accordance with specifications applying to the application. It is recommended that all
cables and cores be fully identified. Use the appropriate cable gland for the application. Gland entry threads are M20-1.5
6H.
Conductive metalwork, including cable glands, must be a minimum of 5 mm away from the terminals.
