Specific Conditions for Safe Use (X):
1. The enclosure contains aluminum and is considered to present a potential risk of
ignition by impact or friction. When installed as EPL Ga, care must be taken during
installation and use to prevent impact or friction.
2. Non-metallic surfaces and the surface of the painted housing may, under certain
extreme conditions, generate an ignition-capable level of electrostatic. Appropriate
measures must be taken to prevent electrostatic discharge.
3. Using the box provided on the nameplate, the User shall permanently mark the
type of protection chosen for the specific installation. Once the type of protection
has been marked it shall not be changed.
4. When installed as Ex ib Ga/Gb, the partition wall materials separating EPL Ga from
EPL Gb are constructed of different materials depending on the antenna option.
Please refer to Control Drawing D9240040-917 for the material type of each
antenna. The material shall not be subject to environmental conditions which might
adversely affect the partition wall.
