Siemens SINUMERIK 840D sl Equipment Manual

Rules for handling backup batteries
WARNING
Incorrect handling of backup batteries can lead to a risk of ignition, explosion and
combustion
The stipulations of DIN EN 60086-4, in particular regarding avoidance of mechanical or
electrical tampering of any kind, must be complied with.
• Do not open a battery. Replace a faulty battery only with the same type.
• Only purchase the batteries through Siemens (see Table 2-3 Ordering data for spare parts /
accessories (Page 22)).
• Always try to return low batteries to the manufacturer or deliver these to a registered
recycling company.
4.2.2 Operating conditions
The components of the SINUMERIK 840D sl system are intended for a weatherproof, 󹪝xed
location. The documented environmental conditions apply to the climate in the immediate
vicinity of the units and to the entry of the cooling air. They exceed the requirements according
to EN 60204-1, EN 61800-2, EN 61131-2 and IEC 62477-1.
