-48 VDC to -40VDC
(operating range: -40.5 VDC to -72 VDC)
45 A maximum at 120 VAC
Accepts 2-14 AWG copper conductors. Actual size of the wire
needed is determined by the installer or local electrician.
Terminal block material rated at 150°C.
For multiple DC input power supplies, each DC input must be
protected by a dedicated two-pole circuit breaker or a fuse.
The circuit breaker or the fuse must be sized according to the
power supply input power rating and any local or national
electrical code requirements.
