When connecting in series, make sure you comply with the wiring technology require-

ments (DIN EN 60204-1) and manipulation protection requirements (EN ISO 14119).

Guidelines for cable length

The max. cable length depends on the voltage drop at the safety switches. The level of
voltage drop is determined by the:
Cable resistance
}
Current of the device and the current load of the outputs

INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with a
wide-range power supply or in AC device versions have internal potential
isolation and are not suitable as evaluation devices.
