2.16 Equipment rating warning
CAUTION
Damage of the device
The PSD is rated at IP67 and an operating temperature range of -20°C to +60°C; do not use the PSD for
conditions beyond these limits.
The PSD battery cannot be charged if its temperature exceeds 40°C.
The MSD is rated at IP30 and a temperature range of -20°C to +60°C, up to 90% non-condensing RH; for
environments harsher than this, use an appropriate secondary enclosure.
Exceeding these ratings could compromise the unit’s ability to stop your machine, which in turn could result in
loss of ability to stop an impending emergency situation and may lead to injury or death.
2.17 Equipment Installation
CAUTION
The choice of connection will be determined by the safety level required for the target application and machine.
To achieve SIL3 capable safety levels, a dual channel connection approach will be required and is
recommended, but single channels are optional for lower safety levels and are also illustrated.
Additionally, it must be remembered that the Ethernet port is not safety-critical, only informational, therefore the
functionality of the green button on the PSD should not be used for safety-critical functionality such as
restarting the machine.
Use of the green button for safety-critical functions could result in unexpected actuation of function and may
lead to injury or death.
2.18 Configuration Changes
WARNING
Users should ensure that whenever a configuration change is made or an additional PSD or MSD is configured
for a system, that the system is tested thoroughly for correct operation before being put into operation.
