Degree of pollution 2
(please note the chapter Maintenance)
TwinSAFE Terminals must not be used under the following
operating conditions:
• under the influence of ionizing radiation (exceeding the
natural background radiation)
• in corrosive environments
• in an environment that leads to unacceptable soiling of the
bus terminal
