• Applying a voltage greater than the limits listed below may damage the input section. For
frequencies above 1 kHz, damage may occur even if the voltage is less than the limits
listed below.
Maximum input voltage between H and L input terminals when the frequency is 1 kHz or
less
1
42 V (DC + ACpeak)
Maximum allowable common mode voltage between the H or L input terminal and the
ground when the frequency is 1 kHz or less
2
42V (DC + ACpeak) (CAT II, 30 Vrms)
• Wire all the L input terminals for all the sub channels on the same module to the same
potential. The L input terminals of the sub channels are all connected. Because the L
input terminals are electrically connected inside the DL850/DL850V, connecting different
potentials to them could result in short circuiting and damage to the 16-CH voltage input
module.

• When you release or lock the terminal block release levers, be careful not to injure yourself
on the levers’ protrusions.
CAUTION
When you attach the terminal block, if you try to attach it upside down, you may damage the
terminal block and the module. Check the vertical orientation of the block before you install it.
