Control wiring for features and options should be connected at the interface terminal blocks located inside the
xStorage 400.
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required. All conduit components and installation methods must be weatherproof.
Read and understand the following notes while planning and performing the installation:
• Use Class 1 wiring methods (as defined by the NEC) for interface wiring from 30V to 600V. The wire
should be rated for 600V, 1A minimum. 12 AWG maximum wire size.
• Use Class 2 wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire should be
rated for 24V, 1A minimum. When Class 2 circuit wiring must be mixed with Class 1 wiring, use Class 1
wire and wiring methods.
• Use twisted-pair wires for each input and return or common.
• All interface wiring and conduit is to be supplied by the installer.
• When installing external interface wiring to the xStorage 400 interface terminals, weatherproof conduit
must be installed between each device and the xStorage 400 enclosure.
• Install the interface wiring in separate weatherproof conduit from the power wiring.
